Ethionamide is used with other medications to treat tuberculosis (TB). Ethionamide is an antibiotic and works by stopping the growth of bacteria.
This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
Take this medication by mouth with or without food, usually once daily or as directed by your doctor. If this medication causes stomach upset or nausea/vomiting, take this medication with meals. Also, discuss with your doctor if it may be helpful to divide your daily dose into smaller doses to be taken several times a day. Follow your doctor's instructions carefully.
The dosage is based on your age, weight, medical condition, and response to treatment.
For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day.
Continue to take this medication (and other TB medications) until the full prescribed amount is finished, even if symptoms disappear. Stopping the medication too early or skipping doses may allow the bacteria to continue to grow, which may result in a return of the infection and cause the infection to be more difficult to treat (resistant).
Your doctor may also direct you to take vitamin B6 (pyridoxine) to help prevent certain side effects (such as nerve problems) from ethionamide. Follow your doctor's instructions carefully.
Tell your doctor if your condition persists or worsens.
Nausea, vomiting, diarrhea, abdominal/stomach pain, increased saliva, strange metallic taste in the mouth, loss of appetite, or sores in the mouth may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication may develop serious side effects, but with frequent visits to your doctor, this risk can be minimized.
