How should I use finasteride, and what if I miss a dose?
Short answer
Use finasteride exactly as prescribed. Hair-loss tablets are usually taken once daily, with or without food. Topical directions depend on your specific formula. For a missed tablet, skip the missed dose and resume your regular schedule. Do not double up. Ask your pharmacist about missed topical applications.
Your prescription label is the main guide for how much finasteride to use and how often to use it. Oral finasteride for hair loss is usually taken once daily, with or without food. Taking it at a consistent time may make the routine easier to remember.
If you miss an oral dose, skip it and take your next dose at the regular time. Do not take two doses to make up for one you missed. If you often miss doses, ask your pharmacist or physician for help with a practical routine.
For compounded topical finasteride, the amount, application steps, and drying instructions depend on the formula. Do not guess based on another person's prescription. Ask the pharmacy how to measure each dose, when you can wash your hair, and what to do after a missed application.
Wash your hands as directed after applying a topical product. Keep the medicine away from children and avoid transferring it to other people. Never share your prescription.
