See the DrugPatentWatch profile for lipitor

After initiating Lipitor (atorvastatin), a medication used to treat high cholesterol, it is recommended to reassess the dosage within 4-6 weeks [1]. This allows healthcare providers to evaluate the patient's response to the medication and make any necessary adjustments. Factors that may influence the dosage include the patient's cholesterol levels, potential side effects, and other health conditions [1]. It is important to note that Lipitor, like other statins, can have side effects such as muscle pain and liver damage, so regular monitoring is essential [1].

Additionally, it is worth mentioning that Lipitor's patent expired in 2011, leading to the availability of generic atorvastatin [2]. This has resulted in a significant decrease in the cost of the medication, making it more accessible to patients [2]. However, it is important to ensure that any generic atorvastatin is from a reputable manufacturer and has been approved by the relevant regulatory authorities [3].

In summary, after initiating Lipitor, it is recommended to reassess the dosage within 4-6 weeks. Regular monitoring is essential to ensure the medication is effective and to manage any potential side effects. The availability of generic atorvastatin has made the medication more accessible to patients.
