Dosing: Adult
Migraine, prevention

Migraine, prevention (alternative agent):

Note: An adequate trial for assessment of effect is considered to be at least 2 to 3 months at a therapeutic dose (Ref).

Oral: Initial: 0.5 mg at bedtime; may increase daily dose in 0.5 mg/day increments every week based on response and tolerability to 1.5 mg/day administered as a single dose at bedtime or in 3 divided doses; average maintenance dose: 1.5 mg/day. Maximum single dose: 3 mg/dose; maximum daily dose: 6 mg/day (Ref).

Discontinuation of therapy: Avoid abrupt discontinuation to minimize withdrawal symptoms (eg, rebound headache, depression, nausea, tremor, anxiety, malaise, dizziness, sleep disorder, loss of consciousness, anorexia, rapid weight loss). The manufacturer recommends a gradual dose reduction over 2 weeks.

Missed dose: Patients taking ≥2 times daily: Administer the missed dose, as soon as possible. If there is <4 hours before the next scheduled dose, then skip the missed dose and resume regular dosing schedule. Do not double dose or administer more than maximum daily dose.

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: Adult

There are no dosage adjustments provided in the manufacturer’s labeling; however, dosage adjustments may be necessary. Use with caution.

Dosing: Liver Impairment: Adult

Hepatic impairment prior to treatment initiation:

There are no dosage adjustments provided in the manufacturer’s labeling; however, dosage adjustments may be necessary. Use with caution.

Hepatotoxicity during treatment:

Discontinue use; do not resume therapy until etiology of hepatic dysfunction is identified.

Dosing: Older Adult

Use with caution. Refer to adult dosing.

Dosing: Pediatric
Migraine, prophylaxis

Migraine, prophylaxis: Children ≥12 years and Adolescents: Oral: Initial: 0.5 mg at bedtime; may increase dose gradually up to maximum of 1 mg at bedtime or a maximum of 1.5 mg/day.

Note: Therapeutic response may require several weeks of therapy. Drug holidays are recommended periodically to assess the need for ongoing therapy. Do not discontinue abruptly (reduce gradually over 2-week period).

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

There are no dosage adjustments provided in the manufacturer’s labeling; however, dosage adjustments may be necessary. Use with caution.

Warnings/Precautions

Concerns related to adverse effects:

• Anticholinergic effects: Although anticholinergic effects (constipation, xerostomia, blurred vision, urinary retention) are limited, use with caution in patients with decreased gastrointestinal motility, myasthenia gravis, paralytic ileus, urinary retention, BPH, xerostomia, narrow-angle glaucoma, or other vision problems.

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Gradual titration of dose may help minimize sedative effects (eg, drowsiness).

• Hepatotoxicity: Hepatotoxic effects may occur with prolonged used; monitor liver function during therapy.

• Visual disturbances: Use has been associated with increased intraocular pressure, diplopia, and pupil dilation; limited number of patients experienced lens opacities but effect was not considered drug-related. Instruct patients to report visual disturbances during therapy.

• Weight gain/loss: Increased appetite and weight gain are common adverse effects; patients may experience rapid weight loss upon discontinuation. Use with caution in obese or other patients who may be vulnerable to these effects.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with cardiovascular disease.

• Diabetes: Use with caution in patients with diabetes mellitus.

• Epilepsy: Use with caution in patients with epilepsy; seizures have been reported very rarely with use.

• Hepatic impairment: Use with caution in patients with hepatic impairment. Dose adjustment may be necessary.

• Renal impairment: Use with caution in patients with renal impairment. Dose adjustment may be necessary.

Dosage forms specific issues:

• Lactose: May contain lactose; avoid use in patients with galactose or fructose intolerance, lactase deficiency, sucrose-isomaltase insufficiency, or glucose-galactose malabsorption.

Other warnings/precautions:

• Abrupt discontinuation: Avoid abrupt discontinuation which may cause acute withdrawal reactions (eg, depression, tremor, nausea, malaise, sleep disorder, dizziness, anxiety, loss of consciousness, anorexia and rapid weight loss); taper dosage over 2 weeks prior to discontinuation.

• Appropriate use: Not for use in acute treatment of migraine attacks or of tension headaches. Not considered first-line agent for migraine prophylaxis but may be considered when other therapies have failed (CHS [Pringsheim 2012]).

• Tolerance: May develop in some patients; effect may be overcome by dose increases (not to exceed maximum dosage). Consider drug-free period after several months of treatment.

Reproductive Considerations

In general, preventive treatment for migraine in patients trying to become pregnant should be avoided. Options for patients planning a pregnancy should be considered as part of a shared decision-making process. Nonpharmacologic interventions should be considered initially. When needed, preventive treatment should be individualized considering the available safety data and needs of the patient should pregnancy occur. A gradual discontinuation of preventive medications is generally preferred when the decision is made to stop treatment prior to conception (ACOG 2022; AHS [Ailani 2021]).

Pregnancy Considerations

Adverse events were not observed in animal reproduction studies.

In general, preventive treatment for migraine should be avoided during pregnancy. Options for pregnant patients should be considered as part of a shared decision-making process. Nonpharmacologic interventions should be considered initially. When needed, preventive treatment should be individualized considering the available safety data, potential for adverse maternal and fetal events, and needs of the patient (ACOG 2022; AHS [Ailani 2021]).

If preventive therapy is needed, agents other than pizotifen are preferred (CHS [Pringsheim 2012]).

Breastfeeding Considerations

It is not known if pizotifen is present in breast milk (Davanzo 2014).

According to the manufacturer, pizotifen is unlikely to affect a breastfeeding infant; however, use is not recommended in breastfeeding patients. In general, preventive treatment for migraine in breastfeeding patients should be avoided. When needed, therapy should be individualized considering the available safety data and needs of the patient (AHS [Ailani 2021]). If preventive therapy is needed, agents other than pizotifen are preferred (CHS [Pringsheim 2012]).

Monitoring Parameters

Hepatic function tests (prolonged use); renal function tests; weight gain; BP; visual disturbance.

Mechanism of Action

Pizotifen is a strong serotonin and tryptamine antagonist with weak antihistamine, anticholinergic and antikinin effects; also has appetite-stimulating and sedative properties. The mechanism of action in migraine prophylaxis has not been fully elucidated; may alter pain thresholds by inhibiting the permeability increasing effect of serotonin and histamine to control movement of plasmakinin across cranial vessel membranes. Inhibits serotonin reuptake by platelets, affecting tonicity and reducing passive distension of extracranial arteries.
