Yes, serious reactions to Lipitor (atorvastatin) and omega-3 fatty acids are possible. According to the prescribing information for Lipitor, serious adverse reactions include myopathy and rhabdomyolysis, which is the breakdown of muscle tissue that can lead to kidney damage [1]. Additionally, omega-3 fatty acids, while generally considered safe, can cause side effects such as bloating, belching, and diarrhea [2].

It is also important to note that while both Lipitor and omega-3 fatty acids can be used to lower cholesterol levels, they are not interchangeable and should not be used as substitutes for one another [3]. Furthermore, combining these two treatments may increase the risk of certain side effects, such as liver enzyme abnormalities [4].

In summary, while both Lipitor and omega-3 fatty acids can be used to lower cholesterol levels, they can also cause serious side effects when used alone or in combination. It is important to consult with a healthcare provider before starting or changing any medication regimen.
