SILDENAFIL
About
SILDENAFIL belongs to the group of medicines called phosphodiesterase type-5 (PDE 5) inhibitors primarily used to treat erectile dysfunction (impotence) in adult men. Additionally, SILDENAFIL may also be used to treat pulmonary arterial hypertension (high blood pressure in the lungs) in adults to improve the ability to exercise and to slow down clinical worsening.
SILDENAFIL works by relaxing the blood vessels in the penis, thereby allowing the blood to flow into the penis when the person is sexually excited. Thus, SILDENAFIL helps treat erectile dysfunction. SILDENAFIL relaxes the blood vessels, increases the blood supply to the lungs and reduces the workload of the heart. Thereby, treating pulmonary hypertension.
You are advised to take SILDENAFIL for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, SILDENAFIL may cause side effects such as headache, nausea, dizziness, indigestion and stomach upset. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Do not take SILDENAFIL if you are allergic to any of the components or if you are taking nitrate medicines or riociguat (a drug used to treat pulmonary hypertension). SILDENAFIL is not recommended for use in children. Consult your doctor if you experience hearing or visual impairment. Avoid consumption of alcohol as it may impair your ability to get an erection. Taking SILDENAFIL after a heavy meal might take longer time for the medicine to work; therefore you are advised to take SILDENAFIL with light meals.

Patients Concern
Disease/Condition Glossary
Erectile dysfunction: It is the inability to keep a hard and erect penis suitable for sexual intercourse. It could be a sign of physical or psychological conditions such as fear of sexual failure, anxiety, depression, low self-esteem, or stress. Certain health-related factors such as smoking, drinking, being overweight, being physically inactive, and high blood pressure also contribute to erectile dysfunction. Symptoms of erectile dysfunction include difficulty in getting an erection, difficulty in maintaining the erection during intercourse and decreased sexual desire.
Pulmonary arterial hypertension (PAH): High blood pressure affects the arteries in the lungs and heart, leading to pulmonary arterial hypertension. It occurs due to narrowed or blocked blood vessels which increases the workload on the heart. Symptoms include chest pain, dizziness, fatigue, and swelling in the legs and ankles.
FAQs
SILDENAFIL works by relaxing the blood vessels in the penis, thereby allowing the blood to flow into the penis when the person is sexually excited.
No, do not take SILDENAFIL with nitrates. Taking SILDENAFIL with medicines used to treat angina/chest pain such as nitrates/nitroglycerin may cause severe lowering of blood pressure. Consult your doctor if you have a history of heart attack/stroke.
Caution is advised if SILDENAFIL is taken with alpha-blockers or blood-pressure-lowering medicines. SILDENAFIL relaxes and widens the blood vessels; this causes a decrease in blood pressure. Therefore, if SILDENAFIL is taken along with blood-pressure-lowering medicines it might cause further lowering in blood pressure. Consult your doctor if you are taking alpha-blockers or anti-hypertensives.
In some cases, SILDENAFIL may cause sudden vision loss in one or both eyes. Stop taking SILDENAFIL and consult your doctor immediately if you experience a sudden decrease or loss of vision.
SILDENAFIL may cause low blood pressure leading to dizziness on standing. If you experience this, do not try to stand up suddenly or start walking; instead, lie down and get up slowly only when you feel better.
