What is Tadalafil?

Tadalafil is a clinically approved erectile dysfunction pill that helps men with ED get and keep harder erections. Tadalafil is the generic equivalent to the brand name drug Cialis. Like Cialis or Viagra®, Tadalafil is a PDE5 inhibitor that relaxes blood vessels and improves blood flow to specific parts of the body, including the penis. Tadalafil can be taken as an "as-needed" tablet before sex (usually 10mg or 20mg), or as a once daily tablet for more spontaneous sex (usually 2.5 mg or 5mg).

Order Tadalafil online

Hims offers access to genuine Tadalafil online. Through our platform, you can get evaluated for ED treatment discreetly, skipping in-person conversations and physical trips to the pharmacy. First, you'll be securely connected online to a UK clinician to evaluate you and answer any questions. If determined to be appropriate by the clinician, you can be prescribed Tadalafil, Sildenafil, or other prescription ED drugs, which will be delivered right to your door at a pace that suits you. Ongoing adjustments are made simple by contacting a clinician through our platform.

How Tadalafil works

Tadalafil (generic for Cialis®) works by promoting a balance of enzymes necessary to produce and maintain an erection. When aroused, the penis produces nitric oxide plus an enzyme that normally gets your penis hard. Like all PDE5 inhibitors, Tadalafil protects the enzyme from breaking down, which results in more blood flow in and less blood flow out. Tadalafil can last for 24-36 hours, so it can support erections longer than other ED pills.

Tadalafil side effects

Side effects most commonly associated with Tadalafil include headaches, flushing, upset stomach, abnormal vision, runny or stuffy nose, back and muscle pain, nausea, dizziness, and rash. If you have any side effects that bother you or do not go away, talk to your clinician. If you have a prolonged erection that lasts longer than 4 hours, you may have a medical condition called priapism, which requires prompt medical treatment. If this happens, seek emergency care immediately.

Tadalafil vs Sildenafil

Both Tadalafil (generic for Cialis®) and Sildenafil (generic for Viagra®) work to help you get it up and keep it up, but there are differences. For starters, you always have to "time" your sex after taking Sildenafil — not so with Tadalafil. Tadalafil works for longer (up to 36 hours) compared with Sildenafil (2 to 4 hours). Tadalafil can be taken as an "as-needed" tablet before sex (usually 10mg or 20mg), or as a once daily tablet for more spontaneous sex (usually 2.5mg or 5mg). Tadalafil can be taken on a full stomach unlike Sildenafil, which is not as effective on a full stomach (e.g. delayed by 60 minutes with a high-fat meal).
