What are the side effects of ethionamide?

People taking ethionamide tablets commonly experience mouth discomfort (soreness, swelling, extra saliva or metallic taste), have stomach upset (nausea, vomiting, diarrhea, stomach ache) or don't feel like eating, even if they don't have any other symptoms. Nerve damage is less common, but it could become serious. Symptoms could start as unusual headaches or a feeling of "pins and needles" in your hands and feet, or you could become clumsy, shaky or unsure of your movements. You might also have mental effects, such as feeling confused, depressed, nervous, restless or like you can't stay awake or concentrate.

Rarely, people have developed partial blindness or blurry vision. You should report any of these symptoms to your doctor. Liver damage is also not as common, but it may make your skin or eyes yellow, which also should be reported to your doctor. People with diabetes may have a harder time managing their blood sugar levels. Some people have developed a rash, sensitivity to light and spontaneous bruising in reaction to this drug. Some people also have developed hypothyroidism or related symptoms: dry skin or acne, swollen skin or neck, a rapid heartbeat, weight gain and feeling cold or hungry. Some women have seen differences in their menstrual periods and some men have experienced an increase in breast size or impotence.
