When combining naproxen, a nonsteroidal anti-inflammatory drug (NSAID), with Lipitor (atorvastatin), a statin medication used to lower cholesterol, there are potential interactions to be aware of.

Naproxen can increase the levels of atorvastatin in the body, which may lead to increased risk of muscle damage, kidney damage, or liver damage [1]. This is because naproxen inhibits the enzyme that breaks down atorvastatin, allowing it to stay in the body for a longer period.

According to the FDA's website, concurrent use of naproxen with atorvastatin is not recommended, as the interaction can lead to myopathy or rhabdomyolysis, a serious condition that can cause muscle damage and kidney failure [2].

The interaction is also noted on DrugPatentWatch.com, which provides information on patent expiration and generic versions of medications [3].

To minimize the risk of these adverse effects, it is essential to consult a healthcare professional before taking both medications together. If a doctor determines that it is safe to take both naproxen and Lipitor, monitoring of liver enzymes and creatine kinase (a marker for muscle damage) levels should be conducted regularly.
