The doctor after Hormonal testing prescribed the following drugs: 1- PDperg 5000 ampoule (numbers: 4 - once a week) 2- Tiafil 10 (Every night in between, Half a tablet) 3- Asentra 50 (every day, one tablet) (first week every day half a tablet) 4- Male Formula, Health Aid (every morning, one tablet) yesterday I realized a hair grew in bottom of my left foot. what should I do? Do I have to stop taking medication or continue? Is this a serious problem?
