Viagra, while effective for many, can cause side effects. Common ones include headache, facial flushing, and nasal congestion. These are usually mild and temporary. A slightly upset stomach is also possible.
More Serious Side Effects
Less common, but more serious, are visual disturbances like blurred vision or changes in color perception. You should seek immediate medical attention if you experience sudden vision loss. Prolonged or painful erections (priapism) are a medical emergency and require immediate treatment.
Heart-Related Side Effects
Important Note: Viagra can interact negatively with nitrates, often prescribed for chest pain. Combining them can significantly lower blood pressure, potentially leading to a heart attack or stroke. Discuss any heart conditions or medications you’re taking with your doctor before using Viagra.
Other potential side effects include: dizziness, hearing loss, and muscle aches. Rarely, allergic reactions may occur.
When to Contact Your Doctor
Contact your doctor immediately if you experience any severe or persistent side effects. They can assess your situation and advise on the best course of action.
