What To Think About
If you are taking antifungal pills, your doctor may monitor your blood count and liver function during treatment to watch for any bad side effects. This may not be needed in people who are otherwise healthy.
Do not drink alcohol while taking terbinafine pills, because this may increase your risk for liver damage.
Allylamine pills should not be taken with some other medicines, such as an excessive amount of acetaminophen (Tylenol). Let your doctor know what other medicines you are taking.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
