There is no such thing as a Viagra 150 mg tablet. The available dosages for Viagra tablets are Viagra 25 mg, Viagra 50 mg, and Viagra 100 mg. It's crucial to only take the dosage that a doctor has prescribed because taking more can increase the likelihood of side effects.

The potential side effects of Viagra can vary depending on the individual and the dosage taken. The most common side effects of Viagra include:

• Headache

• Flushing

• Indigestion

• Nasal congestion

• Dizziness

• Visual changes, such as a blue tint to vision or increased sensitivity to light

These side effects are usually mild and go away on their own. However, if they persist or become severe, it is important to talk to a healthcare provider.
