- Ethionamide is effective only against bacteria. It is not effective for treating viral infections (eg, 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.
