Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood [1]. While it is an effective medication, it can cause some gastrointestinal side effects such as constipation, diarrhea, and stomach pain [1]. If you are experiencing any digestive issues after starting Lipitor, it is important to speak with your healthcare provider.

Probiotics are live microorganisms that can provide health benefits when consumed in adequate amounts [2]. They are commonly used to improve digestive health and can help alleviate symptoms of conditions such as irritable bowel syndrome [2]. However, the effects of probiotics can vary depending on the individual and the specific strain of bacteria consumed [2]. It is important to choose a probiotic supplement that is appropriate for your needs and to speak with your healthcare provider before starting any new supplement regimen [3].

In summary, Lipitor can cause gastrointestinal side effects, and probiotics can be beneficial for digestive health but their effects can vary depending on the individual and the specific strain of bacteria consumed. It is important to speak with your healthcare provider before starting any new medication or supplement regimen [1][2][3].
