Before using Terbinex:
Some medical conditions may interact with Terbinex. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

Some MEDICINES MAY INTERACT with Terbinex. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Amiodarone, cimetidine, fluconazole, or ketoconazole because they may increase the risk of Terbinex's side effects
- Rifampin because it may decrease Terbinex's effectiveness
- Certain antiarrhythmics (eg, flecainide, propafenone), beta-blockers (eg, metoprolol), monoamine oxidase type B (MAO-B) inhibitors (eg, selegiline), selective serotonin reuptake inhibitors (SSRIs) (eg, fluoxetine), or tricyclic antidepressants (eg, amitriptyline, desipramine) because the risk of their side effects may be increased by Terbinex
- Anticoagulants (eg, warfarin) or cyclosporine because their effectiveness may be decreased or the risk of their side effects may be increased by Terbinex
This may not be a complete list of all interactions that may occur. Ask your health care provider if Terbinex may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use Terbinex:
Use Terbinex as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- To use the tablets: Take by mouth with or without food.
- The tablets are usually taken for 6 to 12 weeks, depending on your condition. The full benefit may not be seen for several months after stopping treatment. This includes the time period necessary for healthy nails to grow.
- To use the nail lacquer: Use at bedtime, unless your doctor tells you otherwise. Wash and dry the affected nails, then apply a thin coat of medicine.
- Do not apply the nail lacquer to a wound, or to broken or damaged skin.
- Use the nail lacquer until a new, healthy nail has grown, unless your doctor tells you otherwise. This usually takes 6 to 12 months, depending on your condition.
- To clear up your infection completely, take Terbinex for the full course of treatment. Keep taking it even if you begin to see improvement before the end of your therapy.
- If you miss a dose of Terbinex, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Terbinex.
Important safety information:
- Terbinex only works against fungal infections; it does not treat bacterial or viral infections (eg, the common cold).
- Do NOT take more than the recommended dose or use for longer than prescribed without checking with your doctor.
- Be sure to use Terbinex for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The fungus could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Avoid large amounts of food or drink that have caffeine (eg, coffee, tea, cocoa, cola, chocolate) while you are taking Terbinex.
- Taste changes (eg, taste loss) have been reported in patients taking Terbinex. These effects may resolve within several weeks after you stop taking Terbinex, but may last for a long time (eg, more than one year). Tell your doctor right away if you experience a taste disturbance.
- Rarely, Terbinex may cause severe or even fatal liver problems. If liver problems occur, they may be more severe in patients who have other active liver problems or a history of long-term liver problems. Discuss any questions or concerns with your doctor.
- The nail lacquer is for external use only. Do not get it in your eyes, nose, or mouth. If you get it in any of these areas, rinse right away with cool water.
- You may apply nail polish on top of the nail lacquer.
- Unless you are washing your hands, use gloves while using water or chemical substances to avoid accidentally washing the nail lacquer off. Wearing cotton under the gloves is preferred.
- The nail lacquer is flammable. Do not store or use near an open flame or while smoking.
- Lab tests, including liver function and complete blood cell counts, may be performed while you use Terbinex. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Terbinex should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
- PREGNANCY and BREAST-FEEDING: Do not use Terbinex if you are pregnant. If you think you may be pregnant, contact your doctor right away. Terbinex is found in breast milk. Do not breast-feed while taking Terbinex.
