When combining Lipitor (atorvastatin) with NSAIDs (nonsteroidal anti-inflammatory drugs), there are potential side effects to be aware of. Lipitor is commonly used to lower cholesterol levels, while NSAIDs are used for pain relief and reducing inflammation. The interaction between these medications can increase the risk of kidney damage and muscle problems, such as myopathy or rhabdomyolysis. NSAIDs can also interfere with the effectiveness of Lipitor in lowering cholesterol levels, potentially reducing its benefits. It is important to consult with a healthcare provider before combining these medications to ensure that the benefits outweigh the risks and to monitor for any adverse effects.
