About Isolyte S pH 7.4
What is this medication?
Isolyte S pH 7.4 is a sterile, nonpyrogenic intravenous solution used for fluid and electrolyte replenishment. It contains a balanced mixture of essential minerals including sodium, potassium, magnesium, and chloride. This specific formulation is designed to be isotonic, meaning it has a similar concentration of dissolved particles as human blood, and it is buffered to a physiological pH of 7.4 to closely match the body's natural acid-base balance.
This medication is primarily used to replace water and electrolytes in patients who are unable to maintain adequate oral intake or who have experienced significant fluid loss. It is commonly administered in clinical settings during surgery, after physical trauma, or to treat severe dehydration. Because it includes alkalinizing agents like acetate and gluconate, it also helps in the management of metabolic acidosis by assisting the body in neutralizing excess acid in the bloodstream.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
