The primary side effect of Malegra Pro 100 mg, which contains sildenafil citrate, is similar to other medications in the same class used to treat erectile dysfunction (ED). Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, and common side effects associated with its use include:

Headache: Headaches are among the most frequently reported side effects of sildenafil citrate and can range from mild to moderate in severity. They typically occur shortly after taking the medication and may subside as the drug is metabolized by the body.
Other potential side effects of Malegra Pro 100 mg may include:

Flushing (redness, warmth, or tingling sensation in the face, neck, or chest): This side effect is caused by the dilation of blood vessels, which increases blood flow to certain areas of the body, including the face.

Indigestion (dyspepsia) or upset stomach: Some individuals may experience gastrointestinal symptoms such as indigestion, stomach discomfort, or acid reflux after taking Malegra Pro 100 mg.

Nasal congestion: Sildenafil citrate can cause nasal congestion or a stuffy nose in some individuals, leading to difficulty breathing through the nose.

Dizziness or lightheadedness: Sildenafil citrate may cause dizziness or a sensation of lightheadedness, particularly when standing up from a sitting or lying position. This effect is more common in individuals who take higher doses of the medication or have underlying cardiovascular conditions.

Vision changes: Some individuals may experience changes in vision, such as blurred vision, increased sensitivity to light, or difficulty distinguishing between blue and green colors. These side effects are usually temporary and resolve on their own.

Muscle or back pain: Sildenafil citrate can cause muscle aches or back pain in some individuals, although these side effects are less common compared to others.
