EMBRYO-FETAL TOXICITY AND VENOUS THROMBOEMBOLISM WARNING: EMBRYO-FETAL TOXICITY AND VENOUS THROMBOEMBOLISM See full prescribing information for complete boxed warning. EMBRYO -FETAL TOXICITY • If THALOMID is taken during pregnancy, it can cause severe birth defects or embryo-fetal death. THALOMID should never be used by females who are pregnant or who could be pregnant while taking the drug. Even a single dose [1 capsule (regardless of strength)] taken by a pregnant woman during her pregnancy can cause severe birth defects. • Pregnancy must be excluded before start of treatment. Prevent pregnancy thereafter by the use of two reliable methods of contraception. ( 5.1 , 8.3 ) THALOMID is only available through a restricted distribution program, the THALOMID REMS ® program ( 5.2 ). VENOUS THROMBOEMBOLISM • Significant increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients with multiple myeloma receiving THALOMID with dexamethasone ( 5.3 ). EMBRYO-FETAL TOXICITY If THALOMID is taken during pregnancy, it can cause severe birth defects or embryo-fetal death. THALOMID should never be used by females who are pregnant or who could become pregnant while taking the drug. Even a single dose [1 capsule (regardless of strength)] taken by a pregnant woman during her pregnancy can cause severe birth defects.
Mechanism of action
Sourced from openFDAThe mechanism of action of THALOMID is not fully understood. Cellular activities of thalidomide are mediated through its target cereblon, a component of a cullin ring E3 ubiquitin ligase enzyme complex.
Indications

THALOMID may only be prescribed by prescribers certified with the THALOMID REMS program and may only be dispensed by pharmacists certified with the THALOMID REMS program. 2.2 Recommended Dosage for Multiple Myeloma The recommended dose of THALOMID in combination with dexamethasone is 200 mg once daily (in 28-day treatment cycles) orally with water, preferably at bedtime and at least 1 hour after the evening meal. The dose of dexamethasone is 40 mg daily administered orally on days 1-4, 9-12, and 17-20 every 28 days. 2.3 Recommended Dosage for Erythema Nodosum Leprosum The recommended dose of THALOMID for an episode of cutaneous ENL is 100 to 300 mg/day once daily orally with water, preferably at bedtime and at least 1 hour after the evening meal. Initiate dosing for patients weighing less than 50 kilograms at the low end of the dose range.

Use in specific populations
Sourced from openFDA• Lactation: Advise women not to breastfeed. ( 8.2 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in females exposed to THALOMID during pregnancy as well as female partners of male patients who are exposed to THALOMID. This registry is also used to understand the root cause for the pregnancy. Report any suspected fetal exposure to THALOMID to the FDA via the MedWatch program at 1-800-FDA-1088 and to the REMS Call Center at 1-888-423-5436. Risk Summary Based on the mechanism of action [see Clinical Pharmacology (12.1) ] , human and animal data (see Data ) , THALOMID can cause embryo-fetal harm when administered to a pregnant female and is contraindicated during pregnancy [see Boxed Warning , Contraindications (4.1) , and Warnings and Precautions (5.1) ] . THALOMID is a human teratogen, inducing a high frequency of severe and life-threatening birth defects such as amelia (absence of limbs), phocomelia (short limbs), hypoplasticity of the bones, absence of bones, external ear abnormalities (including anotia, micropinna, small or absent external auditory canals), facial palsy, eye abnormalities (anophthalmos, microphthalmos), and congenital heart defects.
Pharmacokinetics
Sourced from openFDA- Metabolism
- Absorption Absorption of THALOMID is slow after oral administration. The maximum plasma concentrations are reached approximately 2-5 hours after administration.
Overdosage
Sourced from openFDAThere is no specific antidote for a THALOMID overdose. In the event of an overdose, the patient's vital signs should be monitored and appropriate supportive care given to maintain blood pressure and respiratory status.
