Manforce Tablets are phosphodiesterase type-5 inhibitors, a class of medications used mainly to treat erectile dysfunction in adult males. To enhance exercise capacity and prevent clinical deterioration, Manforce can also be used to treat pulmonary arterial hypertension in adults. Back pain, nausea, congestion, headaches, blurred vision, and flushing of the face, neck, or chest are some of the adverse effects of Manforce. If you have recently experienced a stroke or angina (chest pain and discomfort), do not take this tablet. Alcohol causes dizziness during therapy, so restrict or avoid consuming it.
