If thalidomide is taken during pregnancy, it may cause severe birth defects or embryo-fetal death. Thalidomide should never be used by females who are pregnant or who could become pregnant while taking thalidomide. Even a single dose (1 capsule [regardless of strength]) taken by a pregnant woman during pregnancy may cause severe birth defects.
Because of this toxicity and in an effort to make the chance of embryo-fetal exposure to thalidomide as negligible as possible, thalidomide is approved for marketing only through a special restricted distribution program: Thalomid REMS program, approved by the Food and Drug Administration. Information about Thalomid and the Thalomid REMS program is available at https://www.thalomidrems.com or by calling the REMS Call Center at 1-888-423-5436.
The use of thalidomide in multiple myeloma results in an increased risk of venous thromboembolism, such as deep venous thrombosis and pulmonary embolism. This risk increases significantly when thalidomide is used in combination with standard chemotherapeutic agents including dexamethasone. In 1 controlled trial, the rate of venous thromboembolism was 22.5% in patients receiving thalidomide in combination with dexamethasone compared with 4.9% in patients receiving dexamethasone alone (P = 0.002). Patients and physicians are advised to be observant for the signs and symptoms of thromboembolism. Instruct patients to seek medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Consider thromboprophylaxis based on an assessment of individual patients' underlying risk factors.

Altered kidney function:
CrCl >30 mL/minute: Oral: No dosage adjustment necessary (Ref).
CrCl ≤30 mL/minute: Oral: No dosage adjustment necessary (Ref). Close monitoring for hyperkalemia is suggested (Ref). Note: May consider beginning with doses ≤100 mg/day and then titrate upward to indication-specific standard doses based on response and tolerability (Ref).
Augmented renal clearance (measured urinary CrCl ≥130 mL/minute/1.73 m2): Note: 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).
Oral: No dose adjustment necessary (Ref).
Hemodialysis, intermittent (thrice weekly): Dialyzability: Clearance is doubled during dialysis, but the percent of total dose removed is not clinically significant (Ref): Oral: No dose adjustment or supplemental doses are necessary (Ref). Close monitoring for hyperkalemia is suggested (Ref). Note: May consider beginning with doses ≤100 mg/day and then titrate upward to indication-specific standard doses based on response and tolerability (Ref).

For severe cases with moderate to severe neuritis, corticosteroids may be initiated with thalidomide (taper off and discontinue corticosteroids when neuritis improves).
Patients weighing <50 kg: Initiate at lower end of dosage range.
Severe cutaneous reaction or patients previously requiring high doses: May be initiated or increased to 400 mg/day at bedtime or in divided doses.
Maintenance (prevention/suppression, or with flares during tapering attempts): Maintain on the minimum dosage necessary to control the reaction; efforts to taper should be repeated every 3 to 6 months in decrements of 50 mg every 2 to 4 weeks.
Graft-versus-host disease, chronic (refractory), treatment: Limited data available: Children ≥2 years and Adolescents: Oral: Initial: 3 to 6 mg/kg/day (maximum initial daily dose: 100 mg/day) at bedtime or in 2 to 4 divided doses before meals; may be adjusted at ≥2 week intervals based on patient response up to 12 mg/kg/day in 3 to 4 divided doses (maximum daily dose: 800 mg/day) (Ref); one trial used initial doses of 3 mg/kg/dose every 6 hours with dose adjustment to attain thalidomide concentration of ≥5 mcg/mL 2 hours postdose (Ref).
Inflammatory bowel disease, refractory: Limited data available: Note: Use reserved for patients who do not tolerate or have lost response to anti-tumor necrosis factor agents (Ref).
Weight-based dosing (Ref):
Children ≥2 years and Adolescents: Oral: 1.5 to 2.5 mg/kg/dose once daily, usually dosed in the evening; doses as high as 3 mg/kg/dose were described in a small case series. Maximum reported dose in clinical trials is 150 mg/day. Taper to lowest effective dose after remission is achieved.
Fixed dosing:
Adolescents: Oral: Initial: 50 mg once daily; if needed, may titrate dose in 50 mg increments to a maximum of 150 mg daily. Taper to lowest effective dose after remission is achieved (Ref). Fixed initial dosing adjusted for patient weight has also been described in the literature; patients weighing <30 kg received 50 mg once daily, patients weighing 30 to 60 kg received 100 mg once daily, and patients weighing ≥60 kg received 150 mg once daily (Ref).
Dosing based on clinical trials and case reports. In the largest trial, pediatric patients with refractory Crohn disease received fixed thalidomide doses based on weight (n=28; mean age: 14 ± 3.5 years) or placebo (n=26; mean age: 15 ± 3 years); at 8 weeks, 46.4% of patients receiving thalidomide achieved clinical remission, compared to only 11.5% of those receiving placebo (Ref). In another randomized clinical trial, pediatric patients with severe, refractory ulcerative colitis received fixed thalidomide doses based on weight (n=12; mean age: 11.7 years) or placebo (n=11; mean age: 12.9 years). At 8 weeks, 83.3% of patients receiving thalidomide achieved clinical remission, compared to only 18.2% receiving placebo (Ref). In a retrospective study of severe refractory Crohn disease patients (n=12; ages: 8 to 19 years), thalidomide was initiated at 50 mg once daily and titrated by 50 mg increments to a maximum dose of 150 mg. Markers of disease severity significantly improved and long-term follow up found a lower rate of surgical resection from baseline (Ref).
Systemic juvenile idiopathic arthritis, refractory: Limited data available: Children ≥3 years and Adolescents: Oral: Initial: 2 mg/kg/day rounded to the nearest 50 mg dose; if necessary, may increase at 2-week intervals to 3 to 5 mg/kg/day. Dosing based on a multicenter, open-labeled prospective study (n=13, age: 3 to 23 years); 11 of 13 patients showed sustained response with adequate disease control (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Dosing adjustment for toxicity:
ENL, cutaneous:
Children ≥12 years and Adolescents:
ANC ≤750/mm3: Withhold treatment if clinically appropriate.
Angioedema or anaphylaxis: Permanently discontinue therapy.
Constipation, oversedation: Temporarily withhold; consider a reduced dose upon restarting therapy.
Dermatologic reactions:
Grade 2 or 3 rash: Consider interruption or discontinuation of therapy.
Grade 4 rash, skin exfoliation, bullae, or any severe dermatologic reaction: Permanently discontinue therapy.
Grade 3 or 4 adverse reactions: Consider dose reduction, delay, or discontinuation (based on clinical judgment).
Peripheral neuropathy: The manufacturer recommends to temporarily withhold or continue with a reduced dose.
The following adjustments have also been recommended for adult patients with multiple myeloma (Ref):
Grade 1: Reduce dose by 50%.
Grade 2: Temporarily interrupt therapy; once resolved to ≤ grade 1, resume therapy with a 50% dosage reduction (if clinically appropriate).
Grade 3 or higher: Discontinue therapy.
There are no dosage adjustments provided in the manufacturer's labeling. Kidney impairment is not expected to alter drug exposure because <3.5% of dose is excreted as unchanged drug. In a study of 6 adult patients with end-stage renal disease on dialysis, although clearance was increased by dialysis, a supplemental dose was not needed (Ref).
There are no dosage adjustments provided in manufacturer's labeling (has not been studied); however, thalidomide does not appear to undergo significant hepatic metabolism.

Concerns related to adverse effects:
• Bone marrow suppression: May cause leukopenia and neutropenia; avoid initiating therapy if ANC <750/mm3. Persistent neutropenia may require treatment interruption. Thrombocytopenia (including grades 3 and 4) has been reported; may require dose reduction, treatment delay, or discontinuation. Monitor for signs and symptoms of bleeding (including petechiae, epistaxis, and GI bleeding), especially if concomitant medication may increase the risk of bleeding. Monitor CBC with differential and platelets. Anemia has also been observed.
• Bradycardia: May cause bradycardia; use with caution when administering concomitantly with medications that may also decrease heart rate. May require thalidomide dose reduction or discontinuation.
• CNS effects: May cause dizziness, drowsiness, and/or somnolence; caution patients about performing tasks which require mental alertness (eg, operating machinery or driving). Avoid ethanol and concomitant medications that may exacerbate these symptoms; dose reductions may be necessary for excessive drowsiness or somnolence.
• Constipation: Constipation may commonly occur. May require treatment interruption or dosage reduction.
• Dermatologic reactions: Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported (may be fatal). Withhold or discontinue therapy for grade 2 or 3 rash. Permanently discontinue for grade 4 rash or if rash is exfoliative, bullous, or severe (eg, SJS, TEN, DRESS).
• Hepatotoxicity: Abnormal liver function tests, hepatitis, and cholestatic jaundice have been reported. Hepatotoxicity (including hepatocellular and cholestatic injury) has been observed rarely (case reports), with a mean time to development of 46 days; most events resolved after discontinuing thalidomide (Vilas-Boas 2012).
• Hypersensitivity: Hypersensitivity, including angioedema, anaphylactic reaction, and erythematous macular rash, possibly associated with fever, tachycardia, and hypotension, have been reported. Permanently discontinue for angioedema or anaphylaxis. May require treatment interruption for other severe reactions; discontinue if recurs with rechallenge.
• Orthostatic hypotension: May cause orthostatic hypotension; use with caution in patients who would not tolerate transient hypotensive episodes. When arising from a recumbent position, advise patients to sit upright for a few minutes prior to standing.
• Peripheral neuropathy: Thalidomide is commonly associated with peripheral neuropathy; may be irreversible. Neuropathy generally occurs following chronic use (over months), but may occur with short-term use; onset may be delayed. Use caution with other medications that may also cause peripheral neuropathy. Monitor for signs/symptoms of neuropathy monthly for the first 3 months of therapy and regularly thereafter. Electrophysiological testing may be considered at baseline and every 6 months to detect asymptomatic neuropathy. To limit further damage, immediately discontinue (if clinically appropriate) in patients who develop neuropathy. Reinitiate therapy only if neuropathy returns to baseline; may require dosage reduction or permanent discontinuation.
• Secondary malignancy: Increased incidence of second primary malignancies (SPMs), including acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), has been observed in previously untreated multiple myeloma patients receiving thalidomide in combination with melphalan, and prednisone. In addition to AML and MDS, solid tumors have been reported with thalidomide maintenance treatment for multiple myeloma (Usmani 2012). Carefully evaluate patients for SPMs prior to and during treatment and manage as clinically indicated.
• Seizures: Seizures (including grand mal convulsions) have been reported in postmarketing data; monitor closely for clinical changes indicating potential seizure activity in patients with a history of seizures, concurrent therapy with drugs that alter seizure threshold, or conditions that predispose to seizures.
• Thromboembolic events: Thalidomide use for the treatment of multiple myeloma is associated with an increased risk for venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism. Ischemic heart disease, including MI and stroke, also occurred at a higher rate (compared to placebo) in myeloma patients receiving thalidomide plus dexamethasone who had not received prior treatment. Assess individual risk factors for thromboembolism and consider thromboprophylaxis. The American Society of Clinical Oncology guidelines for VTE prophylaxis and treatment recommend thromboprophylaxis for patients receiving thalidomide in combination with chemotherapy and/or dexamethasone; either aspirin or low molecular weight heparin (LMWH) is recommended for lower risk patient and LMWH is recommended for higher-risk patients (Lyman 2013; Lyman 2015). Anticoagulant prophylaxis should be individualized and selected based on the venous thromboembolism risk of the combination treatment regimen, using the safest and easiest to administer (Palumbo 2008). Monitor for signs/symptoms of thromboembolism and advise patients to seek immediate care if symptoms (shortness of breath, chest pain, arm/leg swelling) develop. Other medications that are also associated with thromboembolism should be used with caution.
• Tumor lysis syndrome: Patients with a high tumor burden may be at risk for tumor lysis syndrome; monitor closely; institute appropriate management for hyperuricemia.
Disease-related concerns:
• Heart failure: In a scientific statement from the American Heart Association, thalidomide has been determined to be an agent that may exacerbate underlying myocardial dysfunction (magnitude: minor) (AHA [Page 2016]).
• Multiple myeloma: An increase in mortality was noted in 2 clinical studies in patients with multiple myeloma who received pembrolizumab in combination with a thalidomide analogue and dexamethasone. Causes of death in the experimental arm (containing pembrolizumab, dexamethasone, and a thalidomide analogue [pomalidomide or lenalidomide]) included myocarditis, SJS, MI, pericardial hemorrhage, cardiac failure, respiratory tract infection, neutropenic sepsis, sepsis, multiple organ dysfunction, respiratory failure, intestinal ischemia, cardiopulmonary arrest, suicide, pulmonary embolism, cardiac arrest, pneumonia, sudden death, and large intestine perforation. Multiple myeloma is not an approved indication for PD-1 or PD-L1 blocking antibodies; pembrolizumab should not be used to treat multiple myeloma in combination with a thalidomide analogue and dexamethasone unless as part of a clinical trial.
Special populations:
• Older adult: Certain adverse reactions (constipation, fatigue, weakness, nausea, hypokalemia, hyperglycemia, DVT, pulmonary embolism, atrial fibrillation) are more likely in elderly patients.
• HIV-infected patients: Thalidomide is associated with increased viral loads in studies conducted prior to the use of antiretroviral therapy. Monitor viral load after the first and third months of therapy, and every 3 months thereafter.
Other warnings/precautions:
• Blood donation: Patients should not donate blood during thalidomide treatment and for 4 weeks after therapy discontinuation.
• REMS program: Prescribers and pharmacies must be certified with the program to prescribe or dispense thalidomide. Patients must sign an agreement and comply with the REMS program requirements.

[US Boxed Warning]: Thalidomide should never be used by females who could become pregnant while taking thalidomide. When alternative treatments are not available, females of reproductive potential may be treated when adequate precautions are taken to avoid pregnancy. [US Boxed Warning]: In an effort to make the chance of embryo-fetal exposure to thalidomide as negligible as possible, thalidomide is approved for marketing only through a special restricted distribution program: Thalomid REMS program, approved by the Food and Drug Administration. Information about Thalomid and the Thalomid REMS program is available at https://www.thalomidrems.com or by calling the REMS Call Center 1-888-423-5436.
Females of reproductive potential must avoid pregnancy beginning 4 weeks prior to therapy, during therapy, during therapy interruptions, and for ≥4 weeks after therapy is discontinued. A negative pregnancy test (sensitivity of ≥50 milliunits/mL) 10 to 14 days prior to therapy, within 24 hours prior to beginning therapy, weekly during the first 4 weeks, and every 4 weeks (every 2 weeks for females with irregular menstrual cycles) thereafter is required for women of childbearing potential. Two forms of reliable contraception must be used simultaneously in females of reproductive potential (unless they commit to total abstinence from heterosexual intercourse): One highly effective method (eg, tubal ligation, IUD, hormonal birth control methods) or partners vasectomy; plus one additional effective method (eg, male latex or synthetic condom, diaphragm, or cervical cap). Contraception is required even in cases of infertility (unless due to hysterectomy). Thalidomide must be immediately discontinued for a missed period, abnormal pregnancy test, or abnormal menstrual bleeding. Some forms of contraception may not be appropriate in certain patients. An intrauterine device or implantable contraceptive may increase the risk of infection or bleeding; estrogen-containing products may increase the risk of thromboembolism.
Females of reproductive potential (including health care workers and caregivers) must also avoid contact with thalidomide capsules.
Thalidomide is also present in the semen of males. Males taking thalidomide (even those vasectomized) must use a latex or synthetic condom during any sexual contact with women of childbearing potential and for up to 28 days following discontinuation of therapy. Males taking thalidomide must not donate sperm.
Use is contraindicated in pregnant females. [US Boxed Warning]: If thalidomide is taken during pregnancy, it can cause severe birth defects or embryo-fetal death. Thalidomide should never be used by females who are pregnant or who could become pregnant while taking thalidomide. Even a single dose (1 capsule [regardless of strength]) taken by a pregnant woman during pregnancy may cause severe birth defects. Thalidomide induces a high frequency of severe and life-threatening birth defects. Anomalies observed in humans include amelia, phocomelia, bone defects, ear and eye abnormalities, facial palsy, congenital heart defects, urinary and genital tract malformations; mortality in ~40% of infants at or shortly after birth has also been reported. Discontinue thalidomide immediately if pregnancy occurs during treatment and refer patient to a reproductive toxicity specialist.
A pregnancy exposure registry has been created to monitor outcomes in females exposed to thalidomide during pregnancy and female partners of male patients and to understand the root cause for the pregnancy. The pregnancy exposure registry may be contacted at 1-888-423-5436. If pregnancy occurs during treatment, thalidomide must be immediately discontinued and the patient referred to a reproductive toxicity specialist. Any suspected fetal exposure to thalidomide must be reported to the FDA via the MedWatch program (1-800-FDA-1088) and to the REMS Call Center (1-888-423-5436).
It is not known if thalidomide is present in breast milk. Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer.
CBC with differential, platelets; thyroid function tests (TSH at baseline then every 2 to 3 months during thalidomide treatment [Hamnvik 2011]). Hepatic function tests (periodic; particularly with preexisting hepatic dysfunction or concomitant use of drugs associated with hepatotoxicity). In HIV-seropositive patients: viral load after 1 and 3 months, then every 3 months. Pregnancy testing (sensitivity of at least 50 milliunits/mL) is required 10 to 14 days prior to therapy, within 24 hours prior to initiation of therapy, weekly during the first 4 weeks, then every 4 weeks in females with regular menstrual cycles or every 2 weeks in females with irregular menstrual cycles. Monitor for signs of neuropathy monthly for the first 3 months, then periodically during treatment; consider monitoring of sensory nerve application potential amplitudes (at baseline and every 6 months) to detect asymptomatic neuropathy. Monitor for signs and symptoms of thromboembolism (shortness of breath, chest pain, arm/leg swelling), tumor lysis syndrome, bradycardia, and syncope; monitor for clinical changes indicating potential seizure activity (in patients with a history of seizure). Monitor adherence.
The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Graft-vs-host disease: Therapeutic plasma thalidomide levels are 5 to 8 mcg/mL, although it has been suggested that lower plasma levels (0.5 to 1.5 mcg/mL) may be therapeutic; peak serum thalidomide level after a 200 mg dose: 1.8 mcg/mL
Thalidomide exhibits immunomodulatory and antiangiogenic characteristics; immunologic effects may vary based on conditions. Thalidomide may suppress excessive tumor necrosis factor-alpha production in patients with erythema nodosum leprosum, yet may increase plasma tumor necrosis factor-alpha levels in HIV-positive patients. In multiple myeloma, thalidomide is associated with an increase in natural killer cells and increased levels of interleukin-2 and interferon gamma. Other proposed mechanisms of action include suppression of angiogenesis, prevention of free-radical-mediated DNA damage, increased cell mediated cytotoxic effects, and altered expression of cellular adhesion molecules.
Absorption: Slow, good
Distribution: Vd: 1.1 L/kg
Protein binding: 55% to 66%
Metabolism: Minimal (unchanged drug is the predominant circulating component)
Half-life elimination: 5.5 to 7.3 hours
Time to peak, plasma: ~2 to 5 hours
Excretion: Urine (~92%; <4% of the dose as unchanged drug); feces (<2%)
Hansen disease: Based on data from a small study, in relation to healthy subjects, patients with Hansen disease may have increased thalidomide bioavailability, manifested as increased area under the curve and peak plasma levels.
