What Is Tadalafil?

Tadalafil (Cialis) is a prescription medication used to manage erectile dysfunction. It works by inhibiting phosphodiesterase type 5 (PDE5), which relaxes smooth muscle in blood vessel walls and increases blood flow to the penis during sexual stimulation. With the right dose and ongoing monitoring, most men can achieve and maintain satisfactory erections and enjoy a meaningful improvement in sexual confidence.

Is Online Tadalafil Treatment Right for You?

Tadalafil refills are appropriate for men who have already been diagnosed with erectile dysfunction and have previously been prescribed tadalafil. Candidates should have no recent changes in cardiovascular status and should not be taking nitrates or nitric oxide donors, as the combination can cause dangerous drops in blood pressure.

Because erectile dysfunction can reflect underlying cardiovascular, hormonal, or neurological factors, your prescribing history and any relevant medical conditions will be reviewed by a licensed Doctronic physician before your refill is approved.

Frequently asked questions

Tadalafil is a prescription PDE5 inhibitor that relaxes the smooth muscle in penile blood vessels, allowing increased blood flow when you are sexually stimulated. It is available as a daily low-dose tablet or a higher-dose on-demand tablet taken before sexual activity.

Daily tadalafil (typically 2.5 mg or 5 mg) maintains a steady level of medication in your body so you can respond to sexual stimulation at any time. On-demand tadalafil (10 mg or 20 mg) is taken 30 minutes to 2 hours before anticipated sexual activity and lasts up to 36 hours.

Tadalafil must not be combined with nitrates (such as nitroglycerin or isosorbide), nitric oxide donors, or certain alpha-blockers because the combination can cause a severe and potentially dangerous drop in blood pressure. Always share your full medication list with your Doctronic physician.

The most commonly reported side effects include headache, flushing, nasal congestion, upset stomach, back pain, and muscle aches. These effects are usually mild and temporary. Vision or hearing changes are rare but require prompt medical attention.

Tadalafil has a notably long duration of action, up to 36 hours, which is longer than sildenafil or vardenafil (both typically 4-6 hours) and avanafil (up to 6 hours). This extended window gives couples more flexibility.
