What is the story about ‘Brain Fog’ caused by finasteride?

I’ve been on the Fin and Minox for about a year and a half now. I wasn’t aware of the brain fog side effect of Fin until a few days ago when I researched it, I’ve been struggling with bad brain fog for the past year. I feel dissociated, tired, weak, and like my brain is working at 50% capacity. I chalked this up to me going through a tough time in my personal life but I’m past all of that and the brain fog is still there. I’ve been taking 1.25 mg and I just recently started cutting those in half, so about .625 mg daily before bed. For those who have/had brain fog what would you recommend here to reduce or get rid of brain fog?

If you are one of the few that get ‘Brain Fog’ from finasteride, then stop the drug. We have known that there are central nervous symptoms caused by finasteride since the original research was done, although it was very infrequent.

Storing Propecia in a Cool Place

Hi Dr Rassman,

I need some help with storage of propecia. I live in an area where the weather usually goes up well above 30C (sometimes up to 42C). On the box of propecia, it says it must be stored below 30C. I cannot keep it in the bathroom anymore as its too hot. Should i keep it in the fridge or is that too low of a temperature?

how low can the temperature be for storing purposes? thanks heaps!

In your case, I would store it in your refrigerator, as the temperature in there is going to be below 30C unless it is broken (considering a fridge is normally around 5C). I would wrap it in an insulating type cover, because you would want to avoid condensation.

Stopping Rogaine

doctor,
i have been using rogaine for about 4 years. i went to the 5% a couple of years ago, not too long after that, i only have been applying it a night, because it does tend to irritate my scalp. i thought it was helping me keep the hair i have, no regrown hair at all, but now at age 40, in the last 6 months i have seen an increase in hair loss. i have a good amount of hair on the top, but it is thinning worse and my bald spot has gotten bigger. should i stop rogaine even though i only use it at night, and if i do stop it will it accelerate my hair loss because i have been using it for the last few years? i realize i should have kept up with my dermatologist. any info is appreciated.

The use of Rogaine once a day has poor value. Twice a day is the recommended dosage. If you are a male and you have not started Propecia, then I would suggest that you do so,as it is the best way to control the crown loss and possibly reverse it. That does require a doctor’s prescription and should be accompanied by an examination of your head for miniaturization. If you have any Rogaine dependence (unlikely with a once a day treatment) then withdrawing it might risk more hair loss. So if you are a male, then continue what you are doing and make only one change, taking Propecia for 8 months. If you are a female, then there is no other choice but to go on Rogaine twice a day.

Stopping Propecia After a Month

I am 27 yr old male. Slight thinning in crown for 1 yr. So I took Propecia for 1 month but decided to stop since my thinning process is rather mild. My concern is will my thinning condition worsen with the stopping of propecia after 1 month of consumption. Is my hair already dependent or addicted to the medication? Will my hair thinning process goes back to original speed or end up with accelerating thinning speed?

I doubt that one month of Propecia will have caused dependency. Before you stop it, you should discuss this with your prescribing doctor (as with any prescription medication), and you should be getting your hair mapped out for miniaturization to find out a baseline for genetic hair loss. Maybe you don’t have it, maybe you do. Be smart with the decision and find out.

Stopping minoxidil before a hair transplant

I started using minoxidil earlier this year for my temporal recession (I’ve already been on finasteride for a while). I’ve decided that I would like to pursue a FUE transplant for my temples, eventually. When I think about it, it seems to make sense to stop minoxidil and to wait for the dependent hairs to fall out before getting the transplant. That way, the hairline that is not dependent on topicals emerges, and the transplant can fill those areas as fully as possible. Does that make sense? I haven’t had an initial consult yet and I think I may want to even put that off until after I stop the minoxidil so I can get an evaluation for my hairline without it and then pursue a transplant shortly after.

I tell my patients to continue it for up to 3 days before the hair transplant and then pick it up again at about 1-2 weeks after the transplant so you don’t lose the minoxidil dependent hairs.

Stopping minoxidil and finasteride

Is it possible to keep some of the growth you had if you stop minoxidil and/or finasteride? Or will it eventually fall back to where you started initially?

Any improvements depend upon continuation of these drugs. Stopping them, causes catch up hair loss

Stopping Minoxidil After Just 3 Months

Hi Dr Rassman
I’ve been taking propecia and minoxidil for about 3 months. Now i feel there is improvement in my hair. I am thinking of quiting minoxidil and use propecia only. Would i maintain my hair if i use propecia only. Thanks.

If the minoxidil gave you any improvement, stopping it would see those benefits disappear. Propecia will not maintain any minoxidil benefits for you (and vice versa). If the improvement you saw was from the Propecia, then stopping the minoxidil will be fine. Unfortunately, since you started both at the same time, the only way you’ll really know which medication was working is by stopping one and hoping you made the right choice.

Stopping Finasteride?

I have been on finasteride for over 2 years with good results, but I’ve been dealing with pretty bad sleep/energy/anxiety issues the last ~18 months. (No sexual sides, though.)
I’ve made a lot of lifestyle changes to try to address those issues, but nothing’s really worked. I’m beginning to wonder if the issues are finasteride-related.
I’m thinking about cutting down from 1mg/day to 0.5mg per day for a month or two. Depending on how that goes, I might stay there or continue tapering off.
Is there any general advice regarding lowering/tapering off finasteride dosage?

Reducing your finasteride to half the dose may not have an impact on your hair; however, the more you cut, the greater your risk of losing the hairs you retained. If that happens, you might not get it back. I have seen many patients stop the drug for a couple of months and then lose ground so bad that they never get back to where they were before stopping it. Reducing the dose to every other day or every third day still keeps the drug effective above 50% of the full dose, so this is a reasonable approach if you think that your symptoms are drug-related.

I call that catch up hair loss which means that you lose all of the benefits and revert to what would have happened had you never taken the drug
