Doctors' Answers to "Frequently Asked Questions" - Rogaine
Answer: Topically or systemically? Topical minoxidil has no major side effects and is used for hair growth. Systemic minoxidil is a diuretic used mainly in renal insufficiency patients. Hair growth is the major problem.
Answer: If you have otherwise normal male sexual development, I wouldn't be concerned about this. This would mean normal erections, axillary(armpit)hair, muscle development and male vocal cord size and depth of speech. While Rogaine might help, you will need to probably take it daily for the rest of your life to maintain what it yields. If you do not have normal male development, then you need to see an Internist or Endocrinologist.
Answer: Rogaine is about 30% effective in men and about 80% in women. You will have to
apply it for at least 3-4 months to see an effect and will need to use it forever to keep the
cosmetic results. I recommend that patients take pictures of their hair at the onset of
treatment and a second picture at 3-4 months to see if there is improvement in the number
and thickness of hair. This is how the original research was done. There are minimal side
effects when used topically. This drug is a blood pressure treatment when used internally.
Rare patients absorb enough to feel dizzy on this drug, but this is a rare side effect.
