• if you have a history of certain eye problems (eg, macular degeneration, optic neuropathy, retinitis pigmentosa, sudden vision loss in one or both eyes) or hearing problems (eg, ringing in the ears, decreased hearing, hearing loss)
• if you are dehydrated or have a history of liver or kidney problems, high or low blood pressure, stroke, ulcers, bleeding problems, heart problems (eg, aortic stenosis, angina, irregular heartbeat, heart attack, heart failure), blood vessel problems, or nervous system problems

Some MEDICINES MAY INTERACT with sildenafil. Tell your health care provider if you are taking any other medicines, especially any of the following:

• Alpha-blockers (eg, doxazosin), medicines for high blood pressure, nitrates (eg, isosorbide, nitroglycerin), or nitroprusside because severe low blood pressure with dizziness, light-headedness, and fainting may occur
• Azole antifungals (eg, itraconazole, ketoconazole), H₂antagonists (eg, cimetidine), HIV protease inhibitors (eg, ritonavir, saquinavir), macrolide antibiotics (eg, erythromycin), or telithromycin because they may increase the risk of sildenafil’s side effects

This may not be a complete list of all interactions that may occur. Ask your health care provider if sildenafil may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use sildenafil:

Use sildenafil as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Sildenafil is usually given as an injection at your doctor’s office, hospital, or clinic. If you will be using sildenafil at home, a health care provider will teach you how to use it. Be sure you understand how to use sildenafil. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
• Do not use sildenafil if it contains particles, is cloudy or discolored, or if the vial is cracked or damaged.
• Use sildenafil on a regular schedule to get the most benefit from it. Use it at the same times each day.
• Continue to use sildenafil even if you feel well. Do not miss any doses.
• Do not suddenly stop using sildenafil or change your dose without talking to your doctor.
• Keep this product, as well as syringes and needles, out of the reach of children and away from pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.
• If you miss a dose of sildenafil, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.

Ask your health care provider any questions you may have about how to use sildenafil.

Important safety information:

• Sildenafil may cause drowsiness, dizziness, fainting, or blurred vision. These effects may be worse if you use 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, light-headedness, 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 use sildenafil may be at increased risk of heart-related side effects, including a 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 (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.
• If vomiting or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions.
• 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.
• Tell your doctor or dentist that you take sildenafil before you receive any medical or dental care, emergency care, or surgery.
• Do not use medicines or treatments for ED while you are using 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 approved for use in children. An increase in death has been seen in children as the dose of sildenafil gets higher. However, your child’s doctor may decide the benefits of taking sildenafil may outweigh the risks. Talk with the doctor if you have questions about giving sildenafil to your child.
• PREGNANCY and BREAST-FEEDING: 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 this medicine 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.
