Dosing: Adult

Dosage guidance:

Dosing: For patients with respiratory disease, initiate therapy at the lowest dose (Ref).

Cough, chronic refractory

Cough, chronic refractory (alternative agent) (off-label use): Immediate release: Oral: Initial: 75 mg once daily; may increase gradually over the first week in increments of 75 mg/day based on response and tolerability up to a maximum of 300 mg/day in 3 divided doses (eg, 75 mg in morning and midday with 150 mg in the evening) (Ref).

Fibromyalgia

Fibromyalgia (alternative agent): Note: For patients who do not respond to or tolerate preferred agents (Ref).

Immediate release: Oral: Initial: 75 mg twice daily; may increase to 150 mg twice daily within 1 week based on response and tolerability; maximum dose: 450 mg/day (Ref). Note: Some experts suggest lower initial doses of 25 to 50 mg at bedtime; some patients may respond to maintenance doses <300 mg/day (Ref).

Generalized anxiety disorder

Generalized anxiety disorder (alternative agent) (off-label use): Note: Monotherapy or adjunctive therapy for patients who do not tolerate or respond to preferred agents (Ref).

Immediate release: Oral: Initial: 150 mg/day in 2 to 3 divided doses; may increase based on response and tolerability at weekly intervals in increments of 150 mg/day up to a usual dose of 300 mg/day. May further increase up to 600 mg/day (Ref); however, additional benefit of doses >300 mg/day is uncertain (Ref). Note: Some experts suggest a lower initial dose of 50 mg/day, with an even lower starting dose of 25 mg/day for patients who are sensitive to side effects (Ref).

Neuropathic pain

Neuropathic pain:

General dosing recommendations: Immediate release: Oral: Initial: 25 mg once daily or 50 to 150 mg/day in 2 to 3 divided doses; may increase in increments of 25 to 150 mg/day at weekly intervals based on response and tolerability up to a usual dose of 300 to 600 mg/day in 2 to 3 divided doses (Ref).

Cancer-associated neuropathy (monotherapy or combination therapy) (off-label use): Oral: Immediate release: Initial: 50 to 75 mg twice daily; increase over 1 to 2 weeks based on response and tolerability up to 300 mg twice daily (Ref).

Critically ill ICU patients (monotherapy or combination therapy) (off-label use):

Note: For critically ill patients with neuropathic pain, pregabalin may be a useful component of multimodal pain control (Ref).

Oral: Initial: 75 mg once or twice daily; maintenance dose: 150 to 300 mg twice daily (Ref).

Diabetic neuropathy:

Immediate release: Oral: Initial: 75 to 150 mg/day in 2 to 3 divided doses; may increase daily dose in 75 mg increments every ≥3 days based on response and tolerability up to a maximum dose of 300 to 450 mg/day (Ref). Higher doses up to 600 mg/day may have greater adverse effects without additional benefit (Ref).

Extended release: Oral: Initial: 165 mg once daily; may increase within 1 week based on response and tolerability up to maximum dose of 330 mg once daily.

Postherpetic neuralgia:

Immediate release: Oral: Initial: 150 mg/day in divided doses (75 mg twice daily or 50 mg 3 times daily); may increase to 300 mg/day within 1 week based on response and tolerability; after 2 to 4 weeks, may further increase up to the maximum dose of 600 mg/day.

Extended release: Oral: Initial: 165 mg once daily; may increase to 330 mg once daily within 1 week based on response and tolerability; after 2 to 4 weeks, may further increase up to the maximum dose of 660 mg/day.

Spinal cord injury-associated neuropathic pain: Immediate release: Oral: Initial: 75 mg twice daily; may increase within 1 week based on response and tolerability to 150 mg twice daily; after 2 to 3 weeks, may further increase up to a maximum of 600 mg/day.

Panic disorder

Panic disorder (augmentation) (alternative agent):

Note: Reserve for augmentation of selective serotonin reuptake inhibitor/serotonin and norepinephrine reuptake inhibitor in patients who need rapid symptom relief or who only experience partial relief of symptoms on antidepressant monotherapy (Ref).

Oral: Initial: 50 mg/day; increase daily dose based on response and tolerability in 75 mg increments to a total daily dose of 300 mg/day, in divided doses (Ref).

Pruritus, chronic

Pruritus, chronic (alternative agent) (off-label use): Note: For patients with pruritus resistant to preferred therapies (Ref).

Neuropathic (eg, brachioradial pruritus, notalgia paresthetica) or malignancy related: Based on limited data: Immediate release: Oral: Initial: 75 mg twice daily; may increase based on response and tolerability up to 150 to 300 mg/day in 2 to 3 divided doses (Ref). Higher doses up to 600 mg/day have been used in oncology populations (Ref).

Uremic: Immediate release: Oral: Variable dosing has been used and includes: 50 mg every other day given after dialysis on hemodialysis days (Ref) or 25 mg daily (Ref), each increased based on response and tolerability to 50 or 75 mg daily. 75 mg twice weekly given after dialysis on hemodialysis days also appears effective (Ref).

Restless legs syndrome

Restless legs syndrome (off-label use): Immediate release: Oral: Initial: 50 to 75 mg once daily, 1 to 3 hours before bedtime; gradually increase (eg, in increments of 75 to 150 mg) every 5 to 7 days based on response and tolerability to a usual effective dose of 150 to 450 mg/day (Ref).

Immediate release: Oral: Initial: 100 mg 3 times daily; may increase over 1 week in increments of 150 mg/day based on response and tolerability up to 600 mg/day (Ref).

Vasomotor symptoms associated with menopause

Vasomotor symptoms associated with menopause (alternative agent) (off-label use): Note: Used as a nonhormonal alternative in patients unable or unwilling to take preferred agents (Ref). Some experts prefer gabapentin over pregabalin as an alternative agent because of greater available evidence (Ref).

Immediate release: Oral: Initial: 50 mg once daily at bedtime; may increase at weekly intervals based on response and tolerability to 50 mg twice daily, and then up to 75 mg twice daily; may further increase up to 150 mg twice daily (Ref).

Dosing conversion from immediate-release oral formulations to extended-release oral formulation: Note: On the day of the switch, administer morning dose of immediate-release product as prescribed, and initiate extended-release therapy after the evening meal.

Immediate-release total daily dose of 75 mg is equivalent to extended-release dose of 82.5 mg once daily

Immediate-release total daily dose of 150 mg is equivalent to extended-release dose of 165 mg once daily

Immediate-release total daily dose of 225 mg is equivalent to extended-release dose of 247.5 mg once daily

Immediate-release total daily dose of 300 mg is equivalent to extended-release dose of 330 mg once daily

Immediate-release total daily dose of 450 mg is equivalent to extended-release dose of 495 mg once daily

Immediate-release total daily dose of 600 mg is equivalent to extended-release dose of 660 mg once daily

Discontinuation of therapy: According to the manufacturer, in patients receiving pregabalin chronically, pregabalin should be withdrawn gradually over ≥1 week unless safety concerns require a more rapid withdrawal to minimize the potential of increased seizure frequency (in patients with epilepsy) or other withdrawal symptoms (eg, agitation, confusion, delirium, delusions, GI symptoms, mood changes, sweating, withdrawal seizures). For patients with epilepsy, some experts recommend discontinuing over 3 to 4 months (Ref).

Missed dose: Oral, extended release: If evening meal dose is missed, administer before bedtime following a snack. If missed before bedtime, administer in the morning with a meal. If missed in the morning, wait until the evening meal to take the next scheduled dose.

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Augmented renal clearance (measured urinary CrCl ≥130 mL/minute/1.73 m2): Augmented renal clearance (ARC) is a condition that occurs in certain critically ill patients without organ dysfunction and with normal serum creatinine concentrations. Young patients (<55 years of age) admitted post trauma or major surgery are at highest risk for ARC, as well as those with sepsis, burns, or hematologic malignancies. An 8- to 24-hour measured urinary CrCl is necessary to identify these patients (Ref).

Immediate release: No dosage adjustment necessary; however, may consider increasing dose by 25% if poor response followed by a return to normal dosing as CrCl returns to baseline (Ref).

Extended release: Use not recommended (Ref).

Hemodialysis, intermittent (thrice weekly): Dialyzable (50% to 60%) (Ref):

Note: In a large observational cohort study, pregabalin use in hemodialysis was associated with up to a 51% and 68% higher risk of altered mental status and falls, respectively, compared to no use (Ref). This association was statistically significant, even in dose ranges of ≤100 mg/day. Use pregabalin cautiously in hemodialysis patients at the lowest effective dose with close monitoring (Ref).

Immediate release:

Daily dosing: Initial: 25 mg once daily, may titrate gradually based on tolerability and response to a maximum of 75 mg daily; administer after hemodialysis on dialysis days. A supplemental dose is not needed unless the usual daily dose is administered prior to the dialysis session; if this occurs, a supplementary posthemodialysis dose (50% to 100% of the usual daily dose) may be considered (Ref).

Three times weekly (posthemodialysis) dosing: 25 to 75 mg administered 3 times weekly after hemodialysis on dialysis days has been found to be effective for peripheral neuropathy and uremic pruritus (Ref).

Extended release: Use not recommended.

Peritoneal dialysis:

Immediate release: Initial: 25 mg once daily, may titrate gradually based on tolerability and response to a maximum of 75 mg once daily (Ref). Use cautiously at the lowest effective dose with close monitoring for adverse effects (Ref).

Extended release: Use not recommended (Ref).

CRRT: Drug clearance is dependent on the effluent flow rate, filter type, and method of renal replacement. Recommendations are based on high-flux dialyzers and effluent flow rates of 20 to 25 mL/kg/hour (or ~1,500 to 3,000 mL/hour) unless otherwise noted. Appropriate dosing requires consideration of adequate drug concentrations (eg, site of action is CNS) and indication (eg, antiseizure, analgesic). Close monitoring of response and adverse reactions (eg, confusion, myoclonus, altered mental status) due to drug accumulation is important.

Note: Although not studied in patients receiving CRRT, significant removal of pregabalin is expected based on pharmacokinetic properties (eg, small Vd, low protein binding) (Ref).

Immediate release: Initial: 50 to 75 mg/day in 1 to 2 divided doses; titrate gradually based on tolerability and response up to a maximum of 300 mg/day in 2 to 3 divided doses (Ref).

Extended release: Use not recommended (Ref).

PIRRT (eg, sustained low-efficiency diafiltration): Drug clearance is dependent on the effluent flow rate, filter type, and method of renal replacement. Appropriate dosing requires consideration of adequate drug concentrations (eg, site of action is CNS) and indication (eg, antiseizure, analgesic). Close monitoring of response and adverse reactions (eg, confusion, myoclonus, altered mental status) due to drug accumulation is important.

Note: Although not studied in patients receiving PIRRT, significant removal of pregabalin is expected based on pharmacokinetic properties (eg, small Vd, low protein binding) (Ref).

Immediate release:

PIRRT days: Initial: 50 to 75 mg/day in 1 to 2 divided doses; titrate gradually based on tolerability and response up to a maximum of 300 mg/day in 2 to 3 divided doses (Ref).

Non-PIRRT days: 25 to 75 mg once daily (Ref).

Extended release: Use not recommended (Ref).

Dosing: Hepatic Impairment: Adult

There are no dosage adjustments provided in the manufacturer's labeling. However, no adjustment is expected since undergoes minimal hepatic metabolism.

Dosing: Older Adult

Initiate therapy at the lowest dose (Ref). Refer to adult dosing; use with caution. In the management of restless legs syndrome, a starting dose of 50 mg once daily in patients >65 years has been recommended (Ref).

Dosing: Pediatric

(For additional information see "Pregabalin: Pediatric drug information")

Dosage guidance:

Dosing: When discontinuing, taper off gradually over at least 1 week.

Seizures, partial onset; adjunctive therapy

Seizures, partial onset; adjunctive therapy: Immediate release:

Infants and Children <4 years weighing <30 kg: Oral: Initial dose: 3.5 mg/kg/day in 3 divided doses; dose may be increased weekly based on clinical response and tolerability; maximum daily dose: 14 mg/kg/day.

Children ≥4 years and Adolescents <17 years:

<30 kg: Oral: Initial dose: 3.5 mg/kg/day in 2 or 3 divided doses; dose may be increased weekly based on clinical response and tolerability; maximum daily dose: 14 mg/kg/day.

≥30 kg: Oral: Initial dose: 2.5 mg/kg/day in 2 or 3 divided doses; dose may be increased weekly based on clinical response and tolerability; maximum daily dose: 10 mg/kg/day not to exceed 600 mg/day.

Adolescents ≥17 years: Oral: Initial dose: 150 mg daily in 2 or 3 divided doses; may be increased weekly based on tolerability and effect; maximum daily dose: 600 mg/day.

Fibromyalgia

Fibromyalgia: Limited data available: Immediate release: Children ≥12 years and Adolescents: Oral: Initial: 37.5 mg twice daily for 1 week, then titrate based on clinical response and tolerability to 150 to 450 mg/day in 2 divided doses; maximum daily dose: 450 mg/day. Dosing based on a multi-center, double-blind, placebo-controlled trial (15 weeks) and secondary open-label continuation trial (6 months) (n=107; pregabalin n=54; age range: 12 to 17 years); total daily doses were titrated weekly to an individually optimized dose of 150 mg/day, 300 mg/day, or 450 mg/day; maximum daily dose: 450 mg/day; mean dose during maintenance phase of double-blind study was 244.5 mg/day and in the open label trial it was 254.3 mg/day. Although the primary endpoint of change in mean pain scores from baseline to week 15 was not statistically significant, there was a trend toward improvement in the pregabalin group. Change in weekly mean pain scores was significantly greater with pregabalin compared to placebo for 10 of the 15 weeks; the patient global impression of change was also significantly improved in patients receiving pregabalin (53.1%) compared to placebo (29.5%). The authors reported a large placebo effect, particularly at non-US study centers; however, significance of this is unknown (Ref).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Pediatric

Immediate release: There are no pediatric-specific dosage adjustments provided in manufacturer's labeling (has not been studied); based on experience in adult patients, dosing adjustment may be necessary.

Dosing: Hepatic Impairment: Pediatric

Immediate release: There are no dosage adjustments provided in the manufacturer's labeling; however, no adjustment is expected since pregabalin undergoes minimal hepatic metabolism.

Adverse Reactions (Significant): Considerations
CNS and respiratory depression

Dose-dependent CNS depression may occur and present as somnolence, dizziness, and/or drowsiness. In addition, serious, life-threatening, and fatal respiratory depression may occur; most cases occurred with concomitant use of CNS depressants (especially opioids) in the setting of underlying respiratory impairment or in the elderly (Ref). CNS depression may impair physical or mental abilities and result in accidental injury, including falls.

Mechanism: Dose-related; related to pharmacologic action (ie, structurally related to GABA).

Onset: Varied; timing impacted by concomitant use of medications known to cause CNS depression (eg, opioids) (Ref).

Risk factors:

• Concomitant use of alcohol or other CNS depressants (eg, opioids, benzodiazepines, antidepressants, antihistamines) (Ref)

• Patients with underlying respiratory impairment (Ref)

• Elderly patients (Ref)

Hypersensitivity reactions (delayed)

Isolated cases of delayed hypersensitivity reactions have been reported ranging from maculopapular rashes to severe cutaneous adverse reactions (SCARs), namely drug reaction with eosinophilia and systemic symptoms (DRESS syndrome), Stevens-Johnson syndrome, and toxic epidermal necrolysis (Ref).

Mechanism: Non-dose-related; immunologic. Delayed hypersensitivity reactions are mediated by T-cells or antibodies other than IgE (eg, IgG-mediated, such as some cytopenias) (Ref). SCARs are delayed type IV hypersensitivity reactions involving a T-cell mediated drug-specific immune response (Ref).

Onset: Varied. Type IV reactions are delayed hypersensitivity reactions that typically occur days to weeks after drug exposure, but may occur more rapidly (usually within 1 to 4 days) upon reexposure (Ref).

Risk factors:

Prior history of delayed hypersensitivity reaction to pregabalin. Note: It is unknown whether cross-reactivity exists between gabapentin and pregabalin, given their similar structures. Gabapentinoids are usually considered safe agents for patients with a previous history of drug allergies to other antiseizure medications (Ref).

Peripheral edema

Peripheral edema may occur in patients with or without a prior history of heart failure (Ref). In patients with a prior history of heart failure, peripheral edema may result in acute decompensated heart failure (Ref).

Mechanism: Dose-related; related to pharmacologic action. Exact mechanism not fully established; a possible mechanism may be antagonism of the L-type calcium channels which results in vasodilation of mesenteric resistance arteries. The resultant increased intracapillary hydrostatic pressure leads to increased fluid in the interstitium and peripheral edema (Ref).

Onset: Varied. Onset of symptoms within days of initiation has been described (Ref); whereas, other reports describe onset of symptoms after months of therapy (Ref).

Risk factors:

• Concomitant use of thiazolidinedione antidiabetic agents, particularly in patients with prior cardiovascular disease

• Concomitant use of drugs that may increase risk of peripheral edema

• Preexisting heart failure (NYHA Class III or IV) (cautious use recommended due to limited data in this patient population)

Suicidal ideation and tendencies

Pooled analysis of trials involving various antiseizure medications (regardless of indication) showed an increased risk of suicidal ideation and suicidal tendencies.

Mechanism: Non-dose-related; exact mechanism is not established. Theories include lowering of the threshold for manifesting psychiatric symptoms in patients susceptible to psychiatric disorders or antiseizure-induced disinhibition and impulsiveness thereby influencing and promoting suicidal acts (Ref).

Onset: As early as 1 week after initiation of antiseizure drugs, including gabapentin

Risk factors:

• Preexisting risk factors for suicidal thoughts and behaviors (including epilepsy)

• Prior history of psychiatric disorders or aggressive behaviors (Ref)

Visual disturbances

Blurred vision, decreased visual acuity, amblyopia, diplopia, and visual field loss have been associated with therapy (Ref).

Mechanism: Unknown; likely involves vestibulocerebellar and/or brainstem structures (Ref).

Onset: Varied; effect is dose-dependent (Ref); therefore, timing may be impacted by high doses or accumulation.

Risk factors:

• Conditions which may lead to accumulation (eg, kidney impairment, elderly patients, drug interactions)

Weight gain

Use may cause weight gain. In clinical trials, as highlighted by the manufacturer, average weight gain was 5.2 kg for patients with diabetes receiving pregabalin for ≥2 years. The manufacturer reports that weight gain is not limited to patients with edema and does not appear to be associated with baseline BMI, gender, age, or loss of glycemic control in patients with diabetes.

Mechanism: Dose- and time-related; exact mechanism is unknown. Some observations from preclinical studies suggest that pregabalin may result in an increase in appetite and abdominal fat (Ref).

Onset: Delayed; a pooled analysis aimed at characterizing long-term weight change in pregabalin-treated patients found that 1 in 6 patients who gained ≥7% weight from baseline generally exceeded this level 2 to 12 months after the onset of treatment (Ref).

Risk factors:

• Longer duration of therapy

• Higher doses

Warnings/Precautions

Concerns related to adverse effects:

• Angioedema: Angioedema has been reported during initial and chronic treatment. Use with caution in patients with a history of angioedema episodes. Concurrent use with other drugs known to cause angioedema (eg, ACE inhibitors) may increase risk. Discontinue treatment immediately if angioedema occurs.

Disease-related concerns:

• Renal impairment: Use with caution in patients with renal impairment; dosage adjustment required.

• Substance misuse: Use with caution in patients with a history of substance misuse (Bonnet 2017).

Other warnings/precautions:

• Tumorigenic potential: Increased incidence of hemangiosarcoma noted in animal studies; significance of these findings in humans is unknown.

• Withdrawal: In patients receiving pregabalin chronically, unless safety concerns require a more rapid withdrawal, pregabalin should be withdrawn gradually over ≥1 week (Bonnet 2017; "Gabapentin and Pregabalin" 2012).

Food Interactions

Extended release: Bioavailability is reduced if taken on an empty stomach. The AUC is approximately 30% lower when fasting relative to following an evening meal. Management: Administer after evening meal.

Reproductive Considerations

Pregabalin was found to temporarily decrease mean sperm concentrations; no effects on sperm morphology or motility were observed. Concentrations increased after pregabalin was discontinued. The clinical relevance of this is not known.

Pregnancy Considerations

Pregabalin crosses the placenta (Ohman 2011).

Outcome data following maternal use of pregabalin during pregnancy are available (Dudukina 2023; Nucera 2022; Richardson 2023).

Due to pregnancy-induced physiologic changes, some pharmacokinetic properties of pregabalin may be altered. Theoretically, the increase in renal clearance that occurs during pregnancy may decrease plasma concentrations of pregabalin (Nucera 2022).

Data collection to monitor pregnancy and infant outcomes following exposure to pregabalin is ongoing. Patients exposed to pregabalin during pregnancy are encouraged to enroll themselves into the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling 1-888-233-2334. Additional information is available at www.aedpregnancyregistry.org.

Breastfeeding Considerations

Pregabalin is present in breast milk.

Multiple reports summarize data related to the presence of pregabalin in breast milk:

• Breast milk and maternal plasma were sampled in 10 lactating patients following administration of pregabalin 150 mg every 12 hours for 3 days. Sampling occurred in all patients prior to the first dose on days 1 and 3, then at specified intervals for 24 hours (n = 10) and for 40 to 48 hours (n = 5) following dosing on day 3. Patients did not breastfeed during the study period. Median maximum concentrations of pregabalin were 2.47 mcg/mL (breast milk) and 4.67 mcg/mL (maternal plasm). Maximum concentrations occurred at 4.63 hours (breast milk) and 2.01 hours (maternal plasma). The median half-life of pregabalin was 8.12 and 5.62 hours in breast milk and maternal plasma, respectively. Authors of the study calculated the estimated daily infant dose of pregabalin via breast milk to be 0.379 mg/kg/day (range 0.202 to 0.458 mcg/kg/day) providing a relative infant dose (RID) of 7.18% (range 4.4% to 9.8%) compared to the weight adjusted maternal dose (Lockwood 2016). In general, breastfeeding is considered acceptable when the RID of a medication is <10% (Anderson 2016; Ito 2000).

• Limited data are available following pregabalin use in one patient treated for epilepsy during pregnancy. Pregabalin was detected in the serum of the breastfed infant at ~8% of concentration in the maternal plasma. Adverse events were not observed in the infant (Ohman 2011).

• Poor latch, lasting ~8 hours, was observed in three infants immediately postpartum following a single maternal dose of pregabalin for pain during cesarean delivery (El Kenany 2016).

A case series presented in abstract describes the use of pregabalin to treat persistent severe nipple pain in 4 lactating patients that was presumed to be neuropathic. Patients had an average Visual Analog Scale (VAS) score of 8 and neuropathic pain as evaluated using a neuropathic pain diagnostic questionnaire. Three of the four patients had complete resolution of pain following use of pregabalin and continued exclusive breastfeeding. Adverse events were not observed in the infants. All babies in the study also required interventions to correct sucking (Faraoni 2023).

Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer.

Monitoring Parameters

Measures of efficacy (pain intensity/seizure frequency); degree of sedation; mental alertness; symptoms of respiratory depression and sedation in patients with underlying respiratory disease (FDA 2019); symptoms of myopathy; creatine kinase (as clinically indicated); symptoms of ocular disturbance; weight gain/edema; skin integrity (in patients with diabetes); signs and symptoms of suicidality (eg, suicidal thoughts, anxiety, depression, behavioral changes); platelet count (as clinically indicated)

Mechanism of Action

Binds to alpha-2-delta subunit of voltage-gated calcium channels within the CNS and modulates calcium influx at the nerve terminals, thereby inhibiting excitatory neurotransmitter release including glutamate, norepinephrine (noradrenaline), serotonin, dopamine, substance P, and calcitonin gene-related peptide (Gajraj 2007; McKeage 2009). Although structurally related to GABA, it does not bind to GABA or benzodiazepine receptors. Exerts antinociceptive and antiseizure activity. Pregabalin may also affect descending noradrenergic and serotonergic pain transmission pathways from the brainstem to the spinal cord.
