T max is 2.9 to 5.7 h. Coadministration with a high-fat meal causes minor (less than 10%) changes in AUC and C max ; however, it causes an increase in T max to approximately 6 h.
Not hepatically metabolized to any large extent but appears to undergo nonenzymatic hydrolysis in plasma to multiple metabolites.
Half-life is 5 to 7 h. Renal Cl of 1.15 mL/min with less than 0.7% of the dose excreted in urine as unchanged drug.
Urinary levels were undetectable 48 h after dosing.

The following adverse reactions are treatment-emergent signs and symptoms occurring in thalidomide-treated ENL and multiple myeloma patients. Percentages are listed for adverse reactions occurring in controlled clinical trials. Adverse reactions that do not contain percentages were collected from uncontrolled studies in ENL-treated patients, and the incidence rate cannot be determined. Adverse reactions listed as occurring during treatment of ENL involved thalidomide monotherapy while treatment of multiple myeloma involved coadministration of thalidomide plus dexamethasone.

If thalidomide is taken during pregnancy, it can cause severe birth defects or death to the fetus. Thalidomide should never be used by women who are pregnant or who could become pregnant while taking the drug. It is approved for marketing only under a special restricted distribution program approved by the FDA S.T.E.P.S. program. Only prescribers and pharmacists registered with the program are allowed to prescribe and dispense the product. Patients must be advised of, agree to, and comply with the requirements of the S.T.E.P.S. program in order to receive the product.
Treatment of multiple myeloma with thalidomide results in increased risk of venous thromboembolic events, such as deep vein thrombosis and pulmonary embolus. The risk increases with coadministration of standard chemotherapeutic agents. Patients should seek medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Patients may benefit from concomitant prophylactic anticoagulation or aspirin treatment.
Monitor WBC and differential on an ongoing basis, especially in patients who may be prone to neutropenia (eg, HIV-seropositive). Perform pregnancy tests within 24 h prior to beginning therapy and weekly during the first 4 wk of use, then every 4 wk in women with regular menstrual cycles or every 2 wk in women with irregular cycles. Monitor for signs of neuropathy at monthly intervals for the first 3 mo of therapy. Monitor viral load of HIV-seropositive patients after first and third mo of therapy and every 3 mo thereafter.
Category X. If pregnancy occurs, discontinue treatment immediately.
Safety and efficacy in children younger than 12 yr of age not established.
Has been reported; signs and symptoms may include erythematous macular rash, possibly associated with fever, hypotension, and tachycardia.
May occur; avoid exposure to sunlight or ultraviolet light.
Contraindicated in women of childbearing potential unless alternative therapies are inappropriate and patient meets the following conditions (ie, unable to become pregnant while on thalidomide): understands and can carry out instructions; is capable of complying with mandatory contraceptive measures, pregnancy testing, patient registration, and patient survey described in the S.T.E.P.S. program; received both oral and written warning of hazards of taking thalidomide during pregnancy and of exposing fetus to drug; received oral and written warnings of risk of possible contraception failure and need to use 2 reliable forms of contraception simultaneously, unless continuous abstinence from reproductive heterosexual intercourse is chosen (sexually mature women who have not undergone hysterectomy or who have not been postmenopausal for at least 24 consecutive mo [who have had menses at some time in the preceding 24 consecutive mo] are considered to be of childbearing potential); acknowledges in writing understanding of these warnings and of need for using 2 reliable methods of contraception for 1 mo prior to starting thalidomide therapy, during therapy, and for 1 mo after stopping thalidomide; has had negative pregnancy test with sensitivity of 50 milliunits/mL or greater within 24 h of starting therapy; parent or legal guardian reads this material and agrees to ensure compliance with previous instructions for patients between 12 and 18 yr of age.
Contraindicated in sexually mature males unless the following conditions are met: understands and can carry out instructions; is capable of complying with mandatory contraceptive measures appropriate for men, patient registration, and patient survey as described in S.T.E.P.S. program; received both oral and written warnings of risk of possible contraception failure and of need for barrier contraception (latex condom) in women of childbearing potential (even if he has undergone vasectomy); acknowledges in writing understanding of these warnings and the need for barrier contraception; parent or legal guardian reads this material and agrees to ensure compliance with the previous instructions for patients between 12 and 18 yr of age.
Serious and life-threatening dermatologic reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, may occur.
Physical and psychological dependence not reported in patients taking thalidomide.
