Headache, facial flushing, and nasal congestion are common side effects. These usually mild and temporary.
More serious, though rare, side effects include vision changes (blurred vision, blue tint to vision), prolonged erection (priapism), and hearing loss. Seek immediate medical attention if you experience any of these.
Before taking Viagra, discuss your medical history with your doctor, particularly if you have heart problems, high or low blood pressure, liver or kidney disease, or bleeding disorders. Also mention any other medications you’re taking, including herbal supplements.
Avoid grapefruit juice, as it can interact with Viagra and increase its effects. Alcohol consumption should be moderate. Viagra is designed for use only when sexual stimulation is present. It does not increase libido.
Follow your doctor’s prescribed dosage carefully. Do not exceed the recommended dose. Store Viagra in a cool, dry place, away from direct sunlight and moisture.
