Consult your doctor before starting or continuing long-term Viagra use. Prolonged use can increase the risk of certain side effects.
Hearing problems, including sudden hearing loss, have been reported. This risk seems higher with higher doses or combined use with other medications. Report any hearing changes immediately.
Vision changes, such as blurred vision or blue-tinged vision, are possible. These are usually temporary but require medical attention if persistent or severe.
Priapism, a prolonged and painful erection lasting more than four hours, is a serious complication. Seek immediate medical help if this occurs; it requires prompt treatment to prevent long-term damage.
Heart problems, particularly in men with pre-existing cardiovascular issues, may be exacerbated by Viagra. Chest pain, irregular heartbeat, or shortness of breath warrant immediate medical attention.
Changes in blood pressure are another potential concern, especially for those with hypertension or hypotension. Regular monitoring is crucial for long-term users.
Long-term use might affect liver function. Your doctor may recommend regular liver function tests to monitor this.
Remember, individual responses to medication vary. Open communication with your doctor about any concerns or changes in your health is paramount. They can assess your individual risk factors and adjust treatment accordingly.
