Which medications are contraindicated with pravastatin?

Medications Contraindicated with Pravastatin

Pravastatin has only two absolute contraindications: acute liver failure or decompensated cirrhosis, and hypersensitivity to pravastatin or its excipients 1.

Absolute Contraindications

According to FDA-approved labeling, pravastatin is contraindicated in:

• Acute liver failure or decompensated cirrhosis 1
• Hypersensitivity to pravastatin or any excipients 1

Notably, pravastatin does NOT have the same contraindications as other statins. Unlike simvastatin, gemfibrozil is not formally contraindicated with pravastatin, though it should be avoided.

Medications to Avoid (Not Formally Contraindicated, But Should Not Be Used)

Gemfibrozil - AVOID

The combination of gemfibrozil with pravastatin is potentially harmful and should be avoided 2. This recommendation is based on:

• Pharmacokinetic evidence showing gemfibrozil inhibits glucuronidation pathways, significantly increasing pravastatin concentrations
• FDA-approved product labeling recommends avoiding gemfibrozil with pravastatin 2
• The risk of rhabdomyolysis is approximately 15 times higher with gemfibrozil compared to fenofibrate when combined with statins 2

If fibrate therapy is needed with pravastatin, use fenofibrate or fenofibric acid instead 2. These agents have substantially lower interaction potential and were not associated with rhabdomyolysis in large trials like FIELD and ACCORD 2.

Immunosuppressive Agents - Use With Extreme Caution

While not absolutely contraindicated, pravastatin concentrations increase 5- to 10-fold when combined with cyclosporine 2. The American Heart Association guideline states:

• Limit pravastatin to maximum 20 mg daily when combined with cyclosporine, tacrolimus, everolimus, or sirolimus 2
• The combination may be considered, but requires strict dose limitation and monitoring 2

Important Clinical Context

Pravastatin has a favorable drug interaction profile compared to other statins because:

• It undergoes non-CYP450 metabolism (unlike simvastatin, lovastatin, atorvastatin which use CYP3A4) 2
• It has minimal hepatic metabolism, making it less susceptible to most drug interactions 3
• When statins must be co-prescribed with CYP3A4 inhibitors or competing substrates, pravastatin is often the statin of choice 3

Common Pitfalls to Avoid

1. Do not confuse pravastatin's contraindications with simvastatin's - simvastatin has gemfibrozil as an absolute contraindication; pravastatin does not, though avoidance is still recommended
2. Monitor closely if combining with immunosuppressants - while not contraindicated, dose reduction to ≤20 mg daily is mandatory 2
3. Pregnancy and lactation are no longer contraindications as of 2022 1, though breastfeeding is not recommended during treatment 1
