Atorvastatin, marketed under the brand name Lipitor, is a medication used to lower cholesterol levels in the blood. Patients who take Lipitor may also need pain relief medication, but it is important to ensure that the painkiller is safe to use in combination with atorvastatin.

According to the National Health Service (NHS) [2], some painkillers may interact with atorvastatin and increase the risk of side effects. For example, the NHS advises against taking non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or diclofenac with atorvastatin, as they can increase the risk of muscle problems.

However, there are still some painkillers that are safe to take with atorvastatin. MedlinePlus [3] states that acetaminophen (paracetamol) is safe to use in combination with atorvastatin, as it does not interact with the medication. Additionally, opioids such as codeine and tramadol are also safe to use with atorvastatin, although caution should be taken as these medications can cause drowsiness and dizziness.

It is important to note that patients should always consult their doctor or pharmacist before taking any new medication, including painkillers. They can provide personalized advice on which painkillers are safe to use in combination with atorvastatin based on the patient's medical history and current medications.
