Was using topical minoxidil for past 6+ years without noticeable side effects. However, for past few months I’ve noticed dizziness when standing from a seated or lying position. At first it took me a while to figure out it was the minoxidil, I thought I was developing cardiac failure lol. Took a trial off minox and noticed my dizziness went away and my runs increased dramatically in just a few days! I’m sure it was having subtle cardiac effects for a while I just didn’t realize it! 😂😭
