Fildena 150 contains sildenafil citrate, a medication used primarily to treat erectile dysfunction (ED) by enhancing blood flow to the penis. This dosage is relatively high and may be prescribed when lower doses are not effective. Common side effects can include headaches, flushing, indigestion, and nasal congestion. More serious side effects, though rare, can include sudden vision or hearing loss, chest pain, or prolonged erections (priapism). It’s important to use Fildena 150 mg under the guidance of a healthcare provider to ensure it’s safe and effective for your specific needs.
