There is no enough information yet regarding this matter. I took the time to research, but didn't find the right answer to this. If you are taking several medications, I suggest that you ask your doctor about this, if the medications you are taking are contraindicated or will cause some effects if you use melanotan.
I'd also say that a bit more information is needed for anybody noon here to give you a definite answer, like what medication your actually on for a start. Even then though as far as I know there's no doctors on the site so while its OK getting general information, I do think if your worried then the first place you should go is to your doctor and hetba professional opinion.
I suggest you to not take melanotan with medication that will raise blood pressure, as some people tend to get severe hot flushes after mt2 shot.
Also i never suggest taking melanotan to someone with heart problems, only for healthy individuals really, there is not that much known about melanotan and how it affects us.
Semin, I think you answered your own question. lol! I think that although there aren't any contraindications recorded with melanotan yet, it's still not advisable for people that may have health problems, just like what you said, hypertension, or even those with liver problems.
Melanotan is not liver toxic, no peptides we are discussing on this forum is liver toxic.
