Potential Risks and Side Effects of Viagra and Cialis

Both Viagra (sildenafil) and Cialis (tadalafil) carry potential side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. These usually are mild and temporary. Less common, but more serious, side effects include vision changes (blurred vision, blue-tinted vision), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience a prolonged erection lasting more than four hours. Priapism can cause permanent damage.

Cardiovascular Risks

Viagra and Cialis can lower blood pressure. Individuals with pre-existing heart conditions, such as angina or uncontrolled high blood pressure, should discuss the use of these medications with their doctor. These medications may increase the risk of a heart attack or stroke in susceptible individuals. Always inform your doctor about your complete medical history before starting treatment.

Drug Interactions

These medications can interact with other drugs, including nitrates (used to treat angina). Combining them can lead to a dangerous drop in blood pressure. Avoid grapefruit juice, as it can increase blood levels of both Viagra and Cialis, potentially intensifying side effects. Inform your physician of all medications, supplements, and herbal remedies you are currently taking.
