I may have been on the product longer than anyone here I've been on that Tetralysal 300 stuff for 3 years on was off taking 6 months out of the 3 years break due to not being able to get the product.
This product can't be that dangerous as I can get repeat prescritptions without a doctors consent, but I don't know for sure. One of my toe nails has fungal in it or underneath it, it became yellow over 2 years of taking the antibiotic Tetralysal 300 red/yellow capsules. The side effects I personally got in all the years of using it were on occasion sometimes for almost a day fatigue/shortness of breath/dizziness/tight chest/ feeling of tightness somewhere inside my body it can be a little painful to moderate at times, my teeth aren't as yellow as I thought because I use whitening toothpaste Janina sometimes BlanX stain remover all the time, they seem to work with the IBP Sonic rechargeable toothbrush I got off Amazon, its a great combo works for me.
I used to take it every night before bed I didn't eat anything 1 hour before and since I'm in bed 1 hour after also clear always with plenty of water like a full glass and on an empty stomach they said. I drink 2x the size of a typical whiskey glass but obviously water in it.
My Acne used to be pretty severe but in the week to a month of taking it and lasting about 3 years It cleaned it all up completely, there is faint residue of scarring but thats unavoidable I wish this antibiotic existed when I was 11 I would not have scars now still puts a huge dent in getting a girlfriend and the dent just gets bigger the more acne you have.
I notice when I stopped taking it after 3 years my face was clean for about between 2 weeks to a month, then it came back with a serious vengeance. my face covered with acne some big some small especially near and around the nose where the pores are, some forehead and little on chin too. I realize this tetralysal is not a cure but it is a relief for a time however long you want to take the product, the only downside are the side effects and the possible but extremely rare blood dissorder from taking it plus you could get fungal infection like i did lucky it was only 1 singlular toe nail that was the hue of Yellow and extremely dry nail breaking off. The pain wasn't bad I hardly felt anything odd just its the fact its kinda yellow that looked and felt freakish. Even with fungal infection they are treatable and can heal you back to where you were before.
I started back on it again because my body is immune to Duac and Zynaryt however you spell that, well that and because Its depressing I cant leave the house and do anything with acne on my face. without this antibiotic It takes 6 months to slightly clear up my skin with face products and thats slightly, not worth the time it takes to clear up thus I went back on the Tetralysal 300 I just hope science research in this evolves quickly before I end up taking it for 10 years straight or In case I end up worst off has anyone taken this product more than 3 years straight the long term effects of the antibiotic?
I did a full blood recently nothing came up bad, so even 3 years of taking it didn't effect me much. After starting it back again I'm going to try taking it in the morning 1 hour before breakfast see how that goes as at night I can always use a face product while I sleep keeping it 98.0% Acne free maybe more.
I can say one thing for sure Tetralysal 300 worked for me on some people it can take more time to work. I think I remember my Dr saying your supposed to be taking Tetralysal 300 for longer like a year was it without stopping. Didn't really get that since I've been taking it for 3 years and when stopping Acne just comes back. There's no stopping it, In each of us is the genes that can prevent it or encourage it and the balance in between, Taking it for me means side effects and rare disorders vs clear skin almost 100% of the time I think Its worth the risk being alone and depressed can be one of the worst things in life.
Good luck guys.
