How should I take terbinafine (Lamisil)?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Take the terbinafine tablet with a full glass (8 ounces) of water.

Terbinafine granules should be sprinkled into a spoonful of pudding or mashed potatoes (do not mix with applesauce, fruit juice, or other acidic foods). Swallow this mixture right away without chewing. Do not save the mixture for later use.

The terbinafine granule mixture should be taken with a meal.

Terbinafine is usually taken for 6 to 12 weeks.

Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Terbinafine will not treat a viral infection such as the common cold or flu.

To be sure this medicine is not causing harmful effects, your blood may need to be tested often. Your liver function may also need to be tested. Visit your doctor regularly.

It may take several months for your nails to return to their normal appearance after your treatment with terbinafine.

Store at room temperature away from moisture, heat, and light.

Keep the terbinafine oral granules in their sealed packet until you are ready to use.
