Drug interactions
Major drug interactions
Major:
dextromethorphan terbinafine
Applies to: Kolephrin GG / DM (dextromethorphan / guaifenesin) and terbinafine
Using dextromethorphan together with terbinafine may increase the effects of dextromethorphan. Contact your doctor if you experience difficulty breathing, dizziness, drowsiness, anxiety, restless feeling, nervousness, confusion, or diarrhea. If your doctor does prescribe these medications together, you may need a dose adjustment or extra monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
dextromethorphan Food/Lifestyle
Applies to: Kolephrin GG / DM (dextromethorphan / guaifenesin)
Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
Disease interactions
6 potential interactions Applies to: 6 conditions, including Depression, Lupus Erythematosus, Liver Disease, Immunodeficiency, and Neutropenia.
Depression
Moderate:
terbinafine
Terbinafine has a moderate potential interaction with Depression.
Postmarketing studies have reported depressive symptoms with the use of terbinafine tablets. Terbinafine should be used with caution in patients with depression, and prescribers should be alert to the development of depressive symptoms. Patients and caregivers should be instructed to report any depressive symptoms.
Immunodeficiency
Moderate:
terbinafine
Terbinafine has a moderate potential interaction with Immunodeficiency.
Transient decreases in absolute lymphocyte counts have been reported with oral terbinafine during clinical trials. The clinical significance of these decreases is unknown. Monitoring of complete blood counts may be appropriate in patients with known or suspected immunodeficiency receiving terbinafine for greater than six weeks.
Liver Disease
Major:
terbinafine
Terbinafine has a major potential interaction with Liver Disease.
Oral terbinafine is not recommended for use in patients with chronic or active liver disease. Terbinafine may be hepatotoxic. Rare cases of cholestatic hepatitis and liver failure, some resulting in liver transplant or death, have been reported during treatment of various dermatologic conditions in patients with and without preexisting liver disease. Although a causal relationship has not been established, the severity of hepatic events and/or their outcome may be worse in patients with active or chronic liver disease.
Lupus Erythematosus
Moderate:
terbinafine
Terbinafine has a moderate potential interaction with Lupus Erythematosus.
Precipitation and exacerbation of cutaneous and systemic lupus erythematosus has been reported postmarketing in patients taking terbinafine tablets. Terbinafine should be discontinued in patients with any clinical signs and symptoms suggestive of lupus erythematosus.
Neutropenia
Major:
terbinafine
Terbinafine has a major potential interaction with Neutropenia.
Isolated cases of severe neutropenia have been reported in patients administered oral terbinafine. A causal relationship has not been established, although the neutropenia resolved following discontinuation of terbinafine with or without supportive care. Therapy with terbinafine should be administered cautiously in patients with preexisting neutropenia. It may be appropriate to monitor blood counts more frequently during terbinafine therapy. If secondary infection occurs and the neutrophil count is <= 1000 cells/mm3, terbinafine should be discontinued and supportive management initiated.
Renal Dysfunction
Moderate:
terbinafine
Terbinafine has a moderate potential interaction with Renal Dysfunction.
The use of oral terbinafine in patients with renal impairment (CrCl <= 50 mL/min) has not been adequately studied and is, therefore, not recommended. Terbinafine metabolites are primarily eliminated by the kidney. The clinical significance of possible metabolite accumulation due to decreased clearance is unknown.
