Women taking sildenafil does not usually have an effect on sexual life, on the contrary, may have adverse reactions such as: flushing, low blood pressure, abdominal pain, diarrhea, fever, etc., but it is therapeutic for women with pulmonary arterial hypertension. Sildenafil is mainly used for the treatment of erectile dysfunction in men and the treatment of pulmonary hypertension. Women who take sildenafil will not experience an increase in libido, but may experience adverse reactions such as flushing, hypotension, abdominal pain, diarrhea, and fever as a result of using sildenafil, so ordinary women should avoid using sildenafil.
