What Is Tadalafil?
Tadalafil is a phosphodiesterase type 5 inhibitor, also known as a PDE5 inhibitor. It helps increase blood flow to the penis during sexual stimulation, which can help some adult men with erectile dysfunction achieve and maintain an erection.
Tadalafil does not cause an erection without sexual stimulation. It does not increase sexual desire, does not treat infertility, and does not protect against sexually transmitted infections.
Medicine class: PDE5 inhibitor.Common use: Erectile dysfunction in adult men after medical assessment.Requires: Sexual stimulation to work.Not for: Women, children, or general “vitality” use.Safety priority: Check heart health, blood pressure, nitrate medicines, and drug interactions before use.
Important: Tadalafil can interact dangerously with nitrate medicines used for chest pain and some recreational drugs known as “poppers.” This combination can cause a serious drop in blood pressure. Do not use tadalafil unless it is suitable for your health condition and current medicines.
Why Erectile Dysfunction Should Be Assessed
Erectile dysfunction can be related to stress, fatigue, alcohol, relationship factors, diabetes, high blood pressure, heart disease, medication side effects, hormonal issues, smoking, or circulation problems. For some men, ED can be an early sign of cardiovascular disease.
New or sudden erectile dysfunction should be discussed with a healthcare professional.
Chest pain, shortness of breath, or poor exercise tolerance should be assessed before sexual activity.
Men with diabetes, high blood pressure, heart disease, or kidney disease should ask for medical advice before using ED medicines.
Online or unverified ED medicines may be counterfeit or unsafe.
