What is tadalafil and how does it work?
Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. It is the active ingredient sold under the brand names Cialis, Adcirca, and Alyq. It is FDA-approved to treat erectile dysfunction (ED), the symptoms of benign prostatic hyperplasia (BPH), and ED and BPH together. As Adcirca and Alyq, it is also approved to treat pulmonary arterial hypertension (PAH) to improve the ability to exercise. Tadalafil works by relaxing blood vessels and improving blood flow to specific areas of the body.
A generic version is available, which is why tadalafil typically costs far less than the brand-name Cialis while containing the same active ingredient.
Tadalafil cost and savings without insurance
Because tadalafil is a generic, it is generally already an affordable medication compared with brand-name Cialis. Even so, the cash price can vary a great deal depending on which pharmacy you use, so it pays to compare. There is no manufacturer savings card for generic tadalafil, but a discount coupon can still lower what you pay at the counter.
Rx.com compares tadalafil prices across more than 60,000 pharmacies to help you find the lowest available price nearby. Prices change often and are shown live, so enter your ZIP above to see today's price and print or show your free coupon at the pharmacy.
Tadalafil vs. Cialis and other alternatives
Tadalafil is the same medicine as brand-name Cialis, just sold as a lower-cost generic. Other PDE5 inhibitors used for erectile dysfunction include sildenafil (the generic form of Viagra), vardenafil, and avanafil. They work in similar ways but differ in how quickly they act and how long their effects last.
Which option is right for you depends on your health and how your body responds. Your doctor or pharmacist can help you choose, and you can compare cash prices for each on Rx.com to see which fits your budget.
Important safety information
Tadalafil should never be taken with nitrate medicines such as nitroglycerin or isosorbide, or with riociguat (a guanylate cyclase stimulator), because the combination can cause a severe, life-threatening drop in blood pressure. Do not use tadalafil with recreational nitrates known as "poppers" for the same reason. Use caution if you take alpha-blockers or other blood pressure medicines. Sexual activity may not be advisable for some men with certain heart conditions.
Seek immediate medical care for an erection lasting more than 4 hours (priapism), or for sudden loss of vision or hearing. This is not medical advice; talk with your doctor or pharmacist about your full medical history and other medicines before starting tadalafil.
