Lipitor is a prescription medication used to lower cholesterol levels and reduce the risk of heart disease and stroke. According to the sources provided, Lipitor is not available without a prescription online. Drugpatentwatch [1] indicates that Lipitor is a trademarked drug, and its patent expired in 2011. This means that generic versions of the drug are available, but they still require a prescription. The NHS [2] warns against buying medicines online as it can be dangerous and lead to counterfeit or substandard drugs. Push Health [3] offers an online consultation service with a licensed medical provider who can prescribe Lipitor or its generic equivalent if appropriate. However, it is important to note that this service is not a substitute for a face-to-face consultation with a healthcare provider. In conclusion, Lipitor is not available without a prescription online, and it is essential to exercise caution when purchasing medications online.
