Lamisil (terbinafine) Disease Interactions

There are 6 disease interactions with Lamisil (terbinafine):

Major

Terbinafine (Includes Lamisil) ↔ Liver Disease

Severe Potential Hazard, High plausibility

Applies to: 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.

Major

Terbinafine (Includes Lamisil) ↔ Neutropenia

Severe Potential Hazard, Low plausibility

Applies to: 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.

Moderate

Terbinafine (Includes Lamisil) ↔ Depression

Moderate Potential Hazard, Moderate plausibility

Applies to: 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.

Moderate

Terbinafine (Includes Lamisil) ↔ Immunosuppression

Moderate Potential Hazard, Moderate plausibility

Applies to: 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.

Moderate

Terbinafine (Includes Lamisil) ↔ Lupus

Moderate Potential Hazard, Moderate plausibility

Applies to: 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.

Moderate

Terbinafine (Includes Lamisil) ↔ Renal Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: 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.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.

Do not stop taking any medications without consulting your healthcare provider.
