Lipitor is a brand name for atorvastatin, a medication that is used to lower cholesterol levels in the blood. While Lipitor is generally considered safe, it can cause side effects in some people. The duration of Lipitor side effects can vary depending on the individual and the specific side effect experienced.

According to Medical News Today [2], some common side effects of Lipitor include muscle pain, weakness, and tenderness. These side effects can occur within a few days or weeks of starting Lipitor, but they typically subside within a few weeks after stopping the medication. Other side effects, such as nausea, diarrhea, and constipation, may also occur but usually resolve within a few days.

Drug Patent Watch [1] mentions that while Lipitor is generally well-tolerated, it can cause more serious side effects such as liver problems, memory loss, and confusion. These side effects are rare, but if they occur, they may persist even after stopping the medication. It is important to talk to a doctor if any of these side effects occur.

SingleCare [3] also highlights that Lipitor can cause a rare but serious side effect called rhabdomyolysis, which is the breakdown of muscle tissue that can lead to kidney damage. Symptoms of rhabdomyolysis include muscle pain, weakness, and dark urine. If these symptoms occur, it is important to seek medical attention immediately.

In conclusion, the duration of Lipitor side effects can vary depending on the individual and the specific side effect experienced. Some common side effects may subside within a few weeks after stopping the medication, while more serious side effects may persist even after stopping the medication. It is important to talk to a doctor if any side effects occur, especially if they are severe or persistent.
