Generic Viagra, like its brand-name counterpart, can cause side effects. These are usually mild and temporary, but knowing what to expect is helpful.
- Headache: This is a common side effect. It often resolves on its own, but over-the-counter pain relievers can help. Facial flushing: A reddening of the face and neck. This usually subsides quickly. Indigestion: Some men experience upset stomach or heartburn. Nasal congestion: A stuffy or runny nose is possible. Muscle aches: Mild muscle pain may occur. Visual disturbances: Changes in vision, such as blurred vision or sensitivity to light, can happen, though rarely severely. Back pain: This is relatively infrequent, but possible.
More serious, though rare, side effects include:
- Prolonged erection (priapism): Seek immediate medical attention if an erection lasts longer than four hours. Sudden vision or hearing loss: Consult a doctor immediately if you experience these. Heart attack or stroke: Men with pre-existing heart conditions should discuss potential risks with their physician before taking this medication.
Interactions with other medications are important to consider. Specifically:
Nitrates: Combining Viagra with nitrates (found in some heart medications) can dangerously lower blood pressure. This combination is strictly contraindicated. Alpha-blockers: These medications, often prescribed for high blood pressure or prostate problems, can also interact with Viagra, potentially leading to low blood pressure. Other medications: Always inform your doctor of all medications, supplements, and herbal remedies you are taking. This helps prevent potentially harmful interactions.
If you experience any concerning side effects, discontinue use and consult your doctor.
