Filitra 20 mg, which contains the active ingredient Vardenafil (a PDE5 inhibitor similar to sildenafil or tadalafil), can potentially cause flushing as a side effect. Flushing is a relatively common side effect of PDE5 inhibitors, including Filitra, because they work by increasing blood flow throughout the body, including to the face. This can lead to the characteristic reddening or warmth in the face, neck, and sometimes the chest, which is known as flushing. Why Does Flushing Happen with Filitra 20 mg  Flushing occurs because vardenafil (like other ED medications) causes blood vessels to dilate (widen), improving blood flow. While this is beneficial for increasing blood flow to the penis during sexual arousal, it can also cause blood vessels in other parts of the body (like the face) to expand, leading to the feeling of warmth and redness. How Common Is Flushing? Flushing is a fairly common side effect of PDE5 inhibitors. It tends to be mild and often fades away as the medication wears off. However, some people may experience more noticeable or bothersome flushing, especially at higher doses. Other Common Side Effects of Filitra 20 mg: Along with flushing, Filitra 20 mg can cause other side effects, including: Headaches Dizziness Nasal congestion Indigestion or heartburn Back pain or muscle aches Vision changes (like blurred vision or sensitivity to light, which is less common) When to Seek Medical Help: If the flushing becomes severe or if it's accompanied by other troubling symptoms (like a prolonged erection, chest pain, or difficulty breathing), you should seek medical attention immediately. These could be signs of more serious side effects. Managing Flushing: Avoid alcohol: Drinking alcohol with Filitra may increase the likelihood of flushing, as alcohol itself is a vasodilator (it widens blood vessels). Stay cool: If you feel flushed after taking Filitra, cooling down with a fan or moving to a cooler environment can help. Lower dosage: If flushing is bothersome, consult your doctor. They may suggest adjusting the dose or trying a different ED medication with fewer side effects.
