Does 2.5mg of Fin every other day increase chance of side effects compared to 1.25mg everyday?
Because I cannot cut my generic proscar into 4 pieces, it crumples, and my doctor suggested I split the dose into 2 pieces and take every other day, but I’m worried that starting to take 2.5mg of finasteride when never taking the medicine before might be too excessive? Thank you doctor.
Finasteride stays in your body about a day, so after a day 95%+ will be out of your body. Does the extra dose make for a more effective treatment? Well, that is answered by the science, which showed that higher doses do not impact the value of the drug when treating hair loss. I doubt that there will be more side effects, but frankly I would not know for sure. Each person reacts differently to medication. I would stick to the recommended (or close enough to the recommended) dosage — 1mg daily. Try using a sharp knife to cut the generic Proscar into 4 pieces, rather than using a pill cutter. You may have better luck getting the proper dose that way. Or, you can buy Propecia and get exactly the correct dose without any cutting hassle.
The maturing hairline usually completes the process by the time you reach 30 years old, but there are always exceptions to this. There are some primates that develop a mature hairline or even balding when they pass puberty so we are really not that unique. Hair on your head will absolutely change as you get older, as most people find that the hair grows slower and finer to a different end length. The older you get, the more of these changes that you might see (not everyone, but most people notice it). That gorilla hair type that you may have had when you were 8 years old, will become a distant memory when you get to be 50. 
Speak with your prescribing doctor. With your doctor’s awareness, you might reduce the dose to 1/2 pill (0.5mg) or even 1/4 pill (0.25mg), as some finasteride is better than none in the fight against hair loss. I would want to know more about your sexual problem before I would throw in the towel, so your doctor may give you more insights. If this does not solve the issue, it becomes a personal choice and if it were me, I would take balding over giving up sex (personal choice).
It is a known side effect of Rogaine (minoxidil) that it will grow hair on other parts of the body, possibly from systemic absorption. When the drug was first developed it was used as an antihypertensive and the side effects were not detectable in women treated systemically with abnormal hair growth on the face and elsewhere.
Thank you for the heads up! A number of people sent
