Lipitor (atorvastatin) and aspirin are two commonly prescribed medications used to manage cardiovascular diseases. Lipitor is a statin drug that helps lower cholesterol levels, while aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that is used to reduce inflammation and prevent blood clots.

According to the sources provided, there is no specific recommendation for how often Lipitor and aspirin should be taken together. The dosages and frequency of administration of these medications should be determined by a healthcare professional based on the individual patient's needs and medical history.

Lipitor is typically taken once a day, with or without food, at the same time each day. The dosage may vary depending on the patient's cholesterol levels and response to treatment [1]. Aspirin, on the other hand, is usually taken once a day in low doses (81 mg) to prevent blood clots and reduce the risk of heart attack and stroke [2].

It is important to note that taking Lipitor and aspirin together may increase the risk of bleeding, especially in older adults or people with a history of stomach ulcers or bleeding disorders. Therefore, it is crucial to consult with a healthcare professional before taking these medications together, especially if the patient is already taking other medications or has a pre-existing medical condition [3].

In conclusion, the frequency of taking Lipitor and aspirin together should be determined by a healthcare professional based on the patient's individual needs and medical history. It is important to follow the prescribed dosage and consult with a healthcare professional before taking these medications together to minimize the risk of adverse effects.
