Consult your doctor before using Sildenafil. This is particularly important if you have heart problems, low blood pressure, or a history of stroke. Sildenafil can lower blood pressure, potentially causing dizziness or fainting.
Common Side Effects
Expect some temporary side effects. These commonly include headache, facial flushing, nasal congestion, and visual disturbances such as blurred vision or changes in color perception. These usually resolve on their own. If these effects persist or worsen, seek medical attention immediately.
Less Common but Serious Side Effects
Rarely, Sildenafil can cause more serious side effects including prolonged erection (priapism), requiring immediate medical help. Sudden vision loss or hearing loss are also possible, though uncommon. Report any unusual symptoms promptly to your physician.
Avoid combining Sildenafil with nitrates or other medications for chest pain, as this combination can dangerously lower blood pressure. Inform your doctor of all medications you are currently taking, including over-the-counter drugs and herbal supplements. Grapefruit juice can interact with Sildenafil, so avoid consuming it while using this medication. Finally, alcohol can intensify side effects, so moderate consumption is advised.
