 [ Symptoms ] i have been using minoxidil lotion on my scalp prescribed by a hair loss clinic i am now very worried that i am going to have a heart attack [ Disease ] palpitations is a side effect of minoxidil but it is not a sign of heart disease so you need not to worry about it secondly if the symptoms are disturbing then your trichologist can try to give you a lesser concentration of the solution and see whether symptoms persist or gets better further treatment that is giving finesteride etc can be planned accordingly hope this helps regards…
