Vaniqa PH

Can someone tell me if Vaniqa contains HCl (hydrocloric acid)?

No, Vaniqa does not contain hydrochloric acid.

The generic name for Vaniqa is eflornithine HCL.
HCL is a mere salt compound (one molecule of hydrogen and one molecule of chloride). It is not the same as hydrochloric acid.

Many medications, from mood elevators to diuretics have HCL listed. No need for concern, it’s just the way the drug is made for consumption. Alieve has HCL as one of its ingredients.
