Generic Viagra, like its brand-name counterpart, can cause side effects. Common ones include headache, flushing, nasal congestion, and upset stomach. Less frequent but more serious side effects include vision changes (blurred vision, sensitivity to light), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience a prolonged erection lasting more than four hours.
Common Drug Interactions
Generic Viagra interacts with several medications. It should not be taken with nitrates (used to treat chest pain) due to the risk of dangerously low blood pressure. Caution is advised when using it with alpha-blockers (for high blood pressure or prostate problems), as this combination can significantly lower blood pressure. Other medications that may interact include certain antifungals, HIV protease inhibitors, and some antibiotics. Always inform your doctor about all medications, including over-the-counter drugs and supplements, you are taking before starting generic Viagra. This allows your doctor to assess potential risks and adjust dosages if necessary.
Less Common but Important Interactions
Grapefruit juice can increase Viagra’s concentration in the body, leading to increased side effects. Avoid grapefruit juice while using this medication. Additionally, alcohol can worsen some side effects, so moderation is recommended.
