Yes, Lovegra 100 mg, which contains Sildenafil (the same active ingredient in Viagra), can cause side effects like headaches and dizziness. These are some of the most common side effects of Sildenafil-based medications. Here's why they may occur:

Headaches: Sildenafil works by increasing blood flow, and this can cause dilation (widening) of blood vessels in various parts of the body, including the brain. This vasodilation can lead to headaches as a common side effect.

Dizziness: Sildenafil can lower blood pressure as part of its mechanism of action. This reduction in blood pressure may cause dizziness, especially when standing up quickly, leading to a feeling of lightheadedness or vertigo in some people.

While these side effects are common, they tend to be temporary and usually go away as your body adjusts to the medication. However, if they become severe or persistent, it's important to consult a healthcare provider.

Other common side effects may include:

Flushing (warmth, redness, or tingly feeling)

Nasal congestion

Upset stomach

Vision changes (such as slight blurring or sensitivity to light)

If you're experiencing these symptoms or have concerns about taking Lovegra 100 mg, it's important to discuss them with your healthcare provider. They can help determine whether the medication is suitable for you and offer ways to manage or reduce side effects.
