Warnings

The recommended adult dose is 250 mg once daily. If you have reduced liver or kidney function, your doctor may recommend a lower dose. The length of treatment depends on the condition being treated and the severity of the infection.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones given here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Act Terbinafine exactly as prescribed. Use the medication for the prescribed length of time even if the infection clears up, to prevent it from coming back. If you miss a dose, take it as soon as you remember. If it is the following day before you remember your next dose, skip the missed dose and resume your usual dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Act Terbinafine at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Some people may experience side effects other than those listed. Check with your doctor if you notice any symptom that worries you while you are taking Act Terbinafine.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Act Terbinafine.

Blood counts: Act Terbinafine may decrease the number of neutrophils (a type of white blood cell that helps fight infection), red blood cells (which carry oxygen), and platelets (which help your blood to clot). Your doctor will do blood tests to monitor this. If you notice any signs of infection (e.g., fever, chills, or sore throat) or unusual bleeding or bruising, contact your doctor immediately.

Depression: Rarely, Act Terbinafine has been reported to cause mood swings and symptoms of depression. If you have depression or a history of depression or anxiety, discuss with your doctor how Act Terbinafine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Act Terbinafine, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking Act Terbinafine contact your doctor as soon as possible.

External use only: Terbinafine cream and spray are for external use only. Avoid contact with the eyes. Do not use the spray on the face. In case of accidental contact with the eyes, rinse eyes thoroughly with running water and consult a doctor if any symptoms persist. In case of inhalation, contact a doctor if any symptoms develop and persist. Topical forms of terbinafine are not effective for treating fungal infections of the nails.

Kidney function: The safety and effectiveness of using terbinafine have not been determined for people with decreased kidney function. The kidneys are partially responsible for removing terbinafine from the body. Decreased kidney function may cause terbinafine to build up in the body causing side effects. If you have decreased kidney function, discuss with your doctor how Act Terbinafine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Act Terbinafine, and whether any special monitoring is needed.

Liver function: Terbinafine tablets are not recommended for people with chronic (long-term) or active liver disease. Decreased liver function can cause terbinafine to build up in the body, causing side effects including further liver damage. Your doctor may order liver function tests before you start and while you are taking terbinafine tablets. During treatment with terbinafine, report to your doctor any signs or symptoms of liver problems including unusual fatigue, loss of appetite, yellowing of skin or eyes, abdominal pain, nausea and vomiting, dark urine, pale stools, or itching.

Lupus erythematosus: Occasionally, people taking terbinafine report a flare-up of systemic lupus erythematosus (SLE). If you have SLE, discuss with your doctor how Act Terbinafine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Act Terbinafine, and whether any special monitoring is needed.

Sensory disturbances: People taking terbinafine occasionally experience changes in how they sense things. Vision changes, difficulty hearing, a decreased sense of touch, change in the sense of taste or loss of smell have all been reported. If you notice changes while you are taking Act Terbinafine, contact your doctor.

Pregnancy: Act Terbinafine should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Act Terbinafine, contact your doctor immediately.

Breast-feeding: Act Terbinafine passes into breast milk. If you are a breast-feeding mother and are taking terbinafine, it may affect your baby. Women taking terbinafine tablets should not breast-feed. If you are using the cream or spray, talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using Act Terbinafine have not been established for children.
