Some allopathic medicines for skin conditions can temporarily affect hormones, mood, or blood flow, which may lead to erectile problems or reduced sexual desire. In many cases, erections gradually improve after stopping the medicine, but it may take a few weeks for the body to return to normal. Try to focus on regular exercise, good sleep, stress reduction, and a healthy diet, as these help improve both mood and sexual function. If the problem continues or you also feel depressed, it is best to consult a doctor who can check for possible causes such as stress, hormonal imbalance, or medication side effects and suggest proper treatment or counseling.
