How much does ProSol cost?

Pricing for ProSol varies by insurance plan, dose, and pharmacy. Our database does not show a fixed cost because prices change faster than we can verify. For current pharmacy prices, check your insurance's formulary tier (in the prior-authorization section), use the GoodRx or Cost Plus Drugs deep links on this page, or ask your pharmacist to run a test claim. If a copay card is listed, it usually drops the out-of-pocket significantly for commercial insurance.

About ProSol

What is this medication?

ProSol is a sterile, nonpyrogenic solution of amino acids administered intravenously as a form of parenteral nutrition. It is primarily used to provide a source of nitrogen for patients who are unable to receive adequate nutrition through their digestive system. This medication is typically delivered into a vein, either through a peripheral or central line, depending on the concentration and the specific nutritional needs of the patient.

The medication is specifically designed to promote protein synthesis and maintain a positive nitrogen balance in the body. It is often prescribed for individuals recovering from surgery, trauma, or severe illness who cannot eat by mouth or absorb nutrients through the intestinal tract. By providing essential and non-essential amino acids, ProSol helps prevent the breakdown of muscle tissue and supports overall metabolic functions during periods of physiological stress.

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).
