Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], the most common adverse effects of Lipitor are headache, nausea, diarrhea, muscle pain, and joint pain. Additionally, some patients may experience more severe side effects, such as liver problems, allergic reactions, and an increased risk of developing diabetes.

ACE inhibitors, on the other hand, are a class of drugs commonly used to treat high blood pressure and heart failure. According to the Mayo Clinic [2], common adverse effects of ACE inhibitors include dizziness, fatigue, headaches, dry cough, and skin rash. Additionally, some patients may experience more serious side effects, such as low blood pressure, kidney problems, and angioedema, which is a swelling of the face, lips, tongue, or throat that can be life-threatening.

It is important to note that not all patients will experience adverse effects from these medications, and the severity and frequency of side effects can vary from person to person. It is also important to discuss any concerns or potential side effects with a healthcare provider before starting any new medication.
