MANFORCE 100MG contains Sildenafil which belongs to the group of medicines called Phosphodiesterase type 5 (PDE 5) inhibitors. It is used to treat erectile dysfunction in men. Erectile dysfunction (also known as impotence) is a sexual condition where a man cannot sustain a hard erected penis which is required for normal sexual activity. It happens due to decreased blood flow to the penis which is caused due to narrowing of the blood vessels supplying the penis. Sildenafil improves penile erection (make penis firm) during sexual intercourse. It acts by relaxing the blood vessels supplying the penis which therefore improves penile blood flow and oxygen supply. MANFORCE 100MG would help you to get an erection only if you are sexually stimulated. It is not an aphrodisiac (sex-stimulating agent) and therefore cannot be used to induce sexual thoughts or can improve sexual performance/pleasure in healthy men. It is also not suitable for use in healthy men who do not have erectile dysfunction. It may take around 30 minutes to 1 hour for MANFORCE 100MG to start working, therefore take this medicine at least one hour before planning to have sex. Avoid taking heavy meals while taking MANFORCE 100MG, as it could further delay the onset of action. Before taking MANFORCE 100MG, inform your doctor if you have any liver, kidney, or heart problems. Inform your doctor if you have pulmonary arterial hypertension (increased pressure in the lungs) and taking similar medicines to treat your condition. Avoid taking any other local or oral treatments for erectile dysfunction simultaneously while taking MANFORCE 100MG without consulting your doctor. MANFORCE 100MG is not intended for use in women. It is also not suitable for use in children and adolescents (below 18 years). Inform your doctor if you experience any painful and prolong erection after taking MANFORCE 100MG. The most common side effects of taking MANFORCE 100MG are flushing, headache, dizziness, blurred vision and muscle pain. Consult your doctor if any of the side effect troubles you.
