Rezulin (troglitazone) Disease Interactions

There are 2 disease interactions with Rezulin (troglitazone):

Major

Troglitazone (Includes Rezulin) ↔ Liver Disease

Severe Potential Hazard, High plausibility

Applies to: Liver Disease, Alcoholism

The initiation of troglitazone therapy is contraindicated in patients who have a history of liver disease or alcohol abuse; exhibit clinical evidence of active liver disease; or demonstrate increased serum transaminase levels (ALT > 1.5 times the upper limit of normal). The use of troglitazone has been associated with significant elevations in serum ALT levels as well as severe idiosyncratic hepatocellular injury, which has generally been reversible but, in a few cases, led to liver transplant or death. Injury has occurred after both short- and long-term treatment. Patients who receive troglitazone therapy should have serum transaminase levels checked at the start of therapy, at least monthly for the first year, and at least quarterly thereafter. If signs or symptoms suggestive of liver injury occur, liver function tests should be performed. Moderate elevations (ALT > 1.5 to 2 times ULN) require immediate re-testing and weekly monitoring until levels return to normal. Troglitazone should be withdrawn if ALT rises above 3 times ULN or jaundice develops.

Moderate

Thiazolidinediones (Includes Rezulin) ↔ Macular Edema

Moderate Potential Hazard, Moderate plausibility

Applies to: Macular Edema, Diabetes Mellitus

New onset or worsening diabetic macular edema with decreased visual acuity have been reported in postmarketing reports in some diabetic patients who were taking thiazolidinedione drugs. Some patients presented with blurred vision or decreased visual acuity, but some patients appear to have been diagnosed on routine ophthalmologic examination. Most patients had peripheral edema at the time macular edema was diagnosed. Some patients had improvement in their macular edema after discontinuation of their thiazolidinedione. Patients with diabetes should have regular eye exams by an ophthalmologist according to current standards of care. Additionally, any diabetic who reports any kind of visual symptom should be promptly referred to an ophthalmologist, regardless of the patient's underlying medications or other physical findings.

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.

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