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 Teva Terbinafine.
Blood counts: Teva 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, Teva 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 Teva Terbinafine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva 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 Teva 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 Teva Terbinafine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva 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 Teva Terbinafine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Teva 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 Teva Terbinafine, contact your doctor.
Pregnancy: Teva Terbinafine should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Teva Terbinafine, contact your doctor immediately.
Breast-feeding: Teva 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 Teva Terbinafine have not been established for children.
