Based on the available information, there is no specific mention of a safe amount of fish oil that can be taken with Lipitor (atorvastatin), a medication used to treat high cholesterol. However, both fish oil and Lipitor are known to lower cholesterol and triglyceride levels, so it's important to consult with a healthcare provider before combining the two [1].

Fish oil is generally considered safe when taken in appropriate doses. The FDA has set a maximum limit of 3 grams per day for fish oil, including any EPA and DHA found in fish or fish oil supplements [2]. Exceeding this limit may increase the risk of bleeding and thinning the blood [3].

Lipitor, on the other hand, is a prescription medication and its safe use depends on several factors, including the patient's age, weight, and overall health. The typical starting dose for Lipitor is 10-20 mg per day, and it can be increased up to 80 mg per day based on the patient's response to treatment [4].

It's important to note that combining fish oil and Lipitor may increase the risk of muscle damage (myopathy) and kidney damage (nephrotoxicity) [5]. Therefore, it's crucial to consult with a healthcare provider before taking fish oil with Lipitor.

In conclusion, while fish oil and Lipitor can both be used to lower cholesterol levels, it's important to consult with a healthcare provider before taking them together. The safe amount of fish oil to take with Lipitor will depend on the individual patient's health status and response to treatment.
