Lipitor is a medication used to lower cholesterol levels in the blood [1]. It works by blocking an enzyme that produces cholesterol in the liver. According to the provided source, there is no indication that Lipitor causes dehydration.

Salt substitutes, on the other hand, are used as a low-sodium alternative to table salt. Some salt substitutes contain potassium chloride instead of sodium chloride. Potassium is an essential mineral that helps regulate fluid balance in the body. However, consuming too much potassium can lead to dehydration [2]. Therefore, it is important to use salt substitutes in moderation and consult with a healthcare provider before using them.

Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat high blood pressure and heart failure [3]. According to the provided source, lisinopril can cause dehydration as a side effect. This is because it can increase urination, which can lead to a loss of fluids and electrolytes in the body. It is important to stay hydrated while taking lisinopril and to consult with a healthcare provider if you experience symptoms of dehydration, such as dry mouth, thirst, and dark urine.

In conclusion, Lipitor does not cause dehydration, but salt substitutes and lisinopril can. It is important to use salt substitutes in moderation and consult with a healthcare provider before using them. If you are taking lisinopril, it is important to stay hydrated and consult with a healthcare provider if you experience symptoms of dehydration.
