Tadalafil is a medication used to treat erectile dysfunction and symptoms of benign prostatic hyperplasia (enlarged prostate). It is a type of phosphodiesterase-5 (PDE5) inhibitor, which works by relaxing the muscles and increasing blood flow to the prostate and penis. Tadalafil is available under the brand name Cialis, and it can be taken orally in the form of tablets.
Like all medications, tadalafil can cause side effects, although not everyone will experience them. The most common side effects of tadalafil are headache, indigestion, back pain, muscle aches, and stuffy or runny nose. These side effects usually go away after a few hours.
Other potential side effects of tadalafil include:
- Nausea
- Dizziness
- Flushing (redness or warmth in the face, neck, or chest)
- Vision changes, including sensitivity to light, blurred vision, or seeing a blue tinge to objects
- Rash or itching
- Swelling in the hands, ankles, or feet
Some people may also experience more serious side effects while taking tadalafil, such as an allergic reaction, chest pain, or a prolonged and painful erection (known as priapism). If you experience any of these side effects, you should stop taking tadalafil and seek medical attention immediately.
It is important to note that tadalafil may interact with certain medications, including alpha blockers, nitrates, and other PDE5 inhibitors. It is also not recommended for use in people who have certain health conditions, such as a history of heart attack or stroke, or low blood pressure. Be sure to tell your doctor about all the medications you are taking and any health conditions you have before starting tadalafil.
Overall, tadalafil is a generally safe and effective medication for treating erectile dysfunction and symptoms of an enlarged prostate. However, like all medications, it is important to be aware of potential side effects and to report any unusual symptoms to your doctor.
