Sildenafil, while generally safe, can cause side effects. These vary in frequency and severity. Common side effects include headache, facial flushing, nasal congestion, and indigestion. These usually are mild and temporary.
Less common, but still possible, are visual disturbances such as blurred vision or changes in color perception. Rarely, individuals experience more serious side effects like prolonged erection (priapism), which requires immediate medical attention. This is a medical emergency.
Hearing problems, such as ringing in the ears (tinnitus) or sudden hearing loss, are also possible, though infrequent. If you experience any sudden changes in hearing, seek medical help immediately.
Heart-related side effects, such as chest pain or irregular heartbeat, are uncommon but necessitate immediate medical consultation. Individuals with pre-existing heart conditions should discuss Sildenafil use with their doctor before taking it.
Allergic reactions, manifesting as skin rashes or swelling, are rare. Stop taking Sildenafil and contact a doctor if you develop an allergic reaction.
