Why do you want it banned? If others take it successfully why does that bother you?
I don't, I'm trialing it myself right now.
It's unlikely that this will be banned for hair loss indications for several reasons. You have to consider a few things, namely:
1. The psychological state of post hair transplant patients who rely on the medication to stabilize their hair loss. If the medication was taken off the market, they'd bald around their transplanted hair. Then they would run the risk of not having enough donor hair to fix the damage, or not having enough money to get consecutive transplants to keep up with the balding.
2. Similarly, the psychological state of people who are just staving off their hair loss in general. If this is taken off the market, you're condemning people who are using the medication successfully to continue to bald, which I'd wager would wreak havoc on said individuals psychologically given that they were willing to take a 5ARI to halt their hair loss in the first place.
3. If this was banned, people would seek it from less legitimate sources. These sources would be completely unregulated. This has the potential to cause more problems than the number of people claiming that they have PFS. Either that or they would seek alternative medication like RU58841, which is FAR less researched and has a completely unknown side effect profile in humans.
4. The scientific evidence currently doesn't support banning it. The studies we have on PFS have numerous scientific flaws, including biased sample selections, low sample sizes, in some cases the complete lack of control groups, and generally speaking poor methodologies, to name a few. We need larger clinical trials with properly formulated controls, unbiased sample selection, and sound methodologies to properly assess what the incidence of PFS is, as well as what the underlying risk factors are. Without these clinical trials/studies, there isn't enough statistical evidence to support banning the medication.
I don't think that updating the information label on the medication is an unreasonable demand, but the list is already quite long. Most countries from what I understand already include information about persistent side effects on the information packet.
