Sildenafil citrate is generally used to treat penile erectile dysfunction in men and is not used in women; however, it can be used in women if used to treat pulmonary arterial hypertension.
Sildenafil citrate is a cyclic guanosine monophosphate specific type 5 phosphodiesterase inhibitor that is commonly used clinically to treat penile erectile dysfunction in men and is not used in women for this purpose. Sildenafil citrate is also used clinically to treat pulmonary arterial hypertension, in which case it can be taken by women.
Sildenafil citrate should not be used in combination with nitrate drugs such as isosorbide nitrate and guanylate cyclase agonists such as leucovorin, as this may cause low blood pressure. Adverse reactions such as headache, flushing, dyspepsia and abnormal vision may occur after use.
In conclusion, sildenafil citrate should be used under the supervision of a physician, and if used by women it needs to meet the indications for pulmonary hypertension.
