Understanding Tadalafil Side Effects

Tadalafil Side effects

Tadalafil, a potent PDE5 inhibitor, is highly effective for treating erectile dysfunction (ED). It relaxes muscles and improves blood flow to the genital area, aiding in achieving and maintaining a strong erection during sexual arousal. It’s also used for benign prostatic hyperplasia (BPH) and pulmonary arterial hypertension.

In addition to providing relief, a medicine may also have some unwanted effects. While it’s not guaranteed that you’ll experience these side effects, if you do, it’s important to address them. If you notice any of the following side effects, consider consulting your doctor promptly.
