Important safety information

• Sildenafil may cause dizziness, drowsiness, fainting, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Sildenafil with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Sildenafil may cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
• Patients with heart problems who take Sildenafil may be at increased risk for heart-related side effects, including heart attack or stroke. Symptoms of a heart attack may include chest, shoulder, neck, or jaw pain; numbness of an arm or leg; severe dizziness, headache, nausea, stomach pain, or vomiting; fainting; or vision changes. Symptoms of a stroke may include confusion, vision or speech changes, one-sided weakness, or fainting. Contact your doctor or seek medical attention right away if you experience these symptoms.
• Sildenafil may rarely cause a prolonged (eg, more than 4 hours) or painful erection. This could happen even when you are not having sex. If this is not treated right away, it could lead to permanent sexual problems such as impotence. Contact your doctor right away if you have an erection that lasts more than 4 hours.
• Sildenafil does not stop the spread of HIV or other sexually transmitted diseases (STDs) to others through sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection or an STD.
• Sildenafil will not prevent pregnancy. If your partner may become pregnant and you wish to avoid pregnancy, be sure to use an effective form of birth control.
• Sildenafil may uncommonly cause mild, temporary vision changes (eg, blurred vision, sensitivity to light, blue/green color tint to vision). Contact your doctor if vision changes persist or are severe.
• Rarely, an eye problem called nonarteritic anterior ischemic optic neuropathy (NAION) has been reported in patients who took Sildenafil. This may lead to decreased vision or permanent loss of vision in some cases. If you notice a sudden decrease in vision or loss of vision in one or both eyes, contact your doctor right away.
• Sudden decreases in hearing and loss of hearing have been reported in some patients who have taken Sildenafil. Sometimes they also noticed ringing in the ears or dizziness. If you notice a sudden decrease or loss of hearing, contact your doctor right away.
• Do not use other medicines or treatments for ED while you are taking Sildenafil without first checking with your doctor.
• Use Sildenafil with caution in the ELDERLY; they may be more sensitive to its effects.
• Sildenafil is not recommended for use in CHILDREN; safety and effectiveness in children have not been confirmed.
• PREGNANCY and BREAST-FEEDING: Sildenafil is not approved for use in women. If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Sildenafil while you are pregnant. It is not known if Sildenafil is found in breast milk. If you are or will be breast-feeding while you use Sildenafil, check with your doctor. Discuss any possible risks to your baby
