Important :
- Ethionamide may cause dizziness, lightheadedness, or fainting. Alcohol, hot weather, exercise, and fever can increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Also, sit or lie down at the first sign of dizziness, lightheadedness, or weakness.
- Avoid drinking alcohol or taking other medications that cause drowsiness (e.g., sedatives, tranquilizers) while taking Ethionamide. Ethionamide will add to the effects of alcohol and other depressants. Ask your pharmacist if you have questions about which medicines are depressants.

- Ethionamide is effective only against bacteria. It is not effective for treating viral infections (e.g., the common cold).
- It is important to use Ethionamide for the full course of treatment. Failure to do so may decrease the effectiveness of Ethionamide and may increase the risk that the bacteria will no longer be sensitive to Ethionamide and will not be able to be treated by this or certain other antibiotics in the future.

- Diabetes patients - Ethionamide may affect your blood sugar. Check blood sugar levels closely and ask your doctor before adjusting the dose of your diabetes medicine.
