Contact your doctor immediately if you experience chest pain, irregular heartbeat, or sudden vision changes after taking Viagra. These could be signs of serious side effects.
Seek medical attention if you experience an erection lasting more than four hours (priapism). This is a medical emergency and requires immediate treatment.
Also, contact your doctor if you experience dizziness, nausea, or flushing that is severe or persistent. These are common side effects, but their severity warrants a call to your physician.
Dosage Adjustments and Concerns
If you notice a lack of effectiveness or experience side effects that are bothersome, even if mild, discuss adjusting your dosage with your doctor. They can help determine the best course of action for your individual needs.

Interactions with Other Medications
Always inform your doctor about all medications, supplements, and herbal remedies you are taking before starting Viagra. Some medications can interact negatively with Viagra, potentially causing harmful side effects.
