A phosphodiesterase type 5 inhibitor called Suhagra 100 mg is prescribed to treat erectile dysfunction. The inability to get or keep an erection long enough to engage in sexual activity is known as erectile dysfunction. More blood may enter the penis to achieve an erection since it relaxes the blood vessels there. In cases of pulmonary arterial hypertension, it is also effective. When you remember to take a missed dose, do it right away. If your next dose is almost due, skip the missing one and resume your regular schedule. Never take more than one dose or two doses at once. Don't stop taking this medication or adjust the dosage. Consult the physician. Keep out of children's reach and store in a cold, dry location.
