Does Finasteride lose ability to inhibit hair loss when it's cut into quarters all at once? Should I cut them daily as I use?

Question

Currently the pharmacist cuts 5mg tablets into quarters when I get them. Would it be better if I cut them myself when I take them? They can potentially be sitting in the sealed pill container for weeks at a time until I finish the prescription.

Cutting 5 mg finasteride into quarters does not impact the active medical ingredient finasteride.  They can be stored for a long period of time as cut tablets

William Rassman, MD (retired) · Answer

When you break up a manufactured pill such as finasteride, these cut pills are more susceptible to absorbing water moisture out of the air, so if you feel you must cut them, do that daily
