Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. The drug is effective in reducing the risk of heart attack, stroke, and other cardiovascular diseases [1]. However, like all medications, Lipitor has potential side effects, especially when taken in excess of the recommended dosage limits.

According to the drug label provided by the FDA, the recommended starting dose of Lipitor is 10 or 20 mg once daily. The maximum recommended dose is 80 mg once daily for adults [2]. Exceeding this limit may increase the risk of side effects, including muscle damage, liver problems, and kidney failure. The drug label also warns against using Lipitor with certain medications that may increase the risk of side effects [2].

Medscape reports that common side effects of Lipitor include headache, muscle pain, weakness, and stomach pain. Less common but more serious side effects may include rhabdomyolysis (a condition that causes muscle breakdown), liver damage, and kidney failure [3].

It is important to note that Lipitor should only be taken under the supervision of a healthcare provider who can monitor the patient's cholesterol levels and adjust the dosage as needed. Patients should also report any side effects they experience while taking Lipitor to their healthcare provider immediately.

In conclusion, exceeding the recommended dosage limits of Lipitor may increase the risk of side effects, including muscle damage, liver problems, and kidney failure. Patients should only take Lipitor under the supervision of a healthcare provider and report any side effects immediately.
