Thalidomide: From Tragedy to Modern Medicine
Thalidomide was first introduced in 1957 as a sedative and was later prescribed for morning sickness during pregnancy. It was withdrawn after being linked to severe birth defects in thousands of babies. The tragedy changed global drug approval and pharmacovigilance practices forever.
Current Medical Uses
- Multiple myeloma – Used in combination with other medicines to treat this blood cancer.
- Erythema nodosum leprosum (ENL) – Controls the painful inflammatory reactions associated with leprosy.
How Does It Work?
Thalidomide modifies the immune system, reduces inflammation, and blocks the formation of new blood vessels that help certain cancer cells grow.
Common Adverse Effects
- Drowsiness
- Constipation
- Peripheral neuropathy (nerve damage)
- Dizziness
- Increased risk of blood clots
Contraindications
- Pregnancy (causes severe birth defects)
- Hypersensitivity to thalidomide
- Use with caution in patients at high risk of thrombosis or with existing peripheral neuropathy.
Monitoring
Patients require regular follow-up, pregnancy prevention measures, and monitoring for nerve damage and blood clots throughout treatment.
Conclusion
Thalidomide is a reminder that even a drug with a tragic past can become a valuable treatment when used responsibly and with proper safety measures.
