What is Tadalafil?

Tadalafil is the active ingredient in brand-name Cialis®. It's an FDA-approved medication for erectile dysfunction that works by increasing blood flow to the penis when you're sexually aroused.

How do I take it?

You have two options:

As-Needed (10-20mg):

  • Take 30-60 minutes before sexual activity
  • Effective for up to 36 hours
  • Don't take more than once per 24 hours

Daily (5mg):

  • Take at the same time every day
  • Be ready whenever the moment strikes
  • No planning required

Your provider will recommend the best approach based on your lifestyle.

How quickly will I receive my medication?

Tadalafil is nicknamed "The Weekend Pill" for a reason, it can remain effective for up to 36 hours after taking it.

This doesn't mean a 36-hour erection (that would be a medical emergency!). It means you can achieve erections with sexual stimulation at any point during that window.

Fast When You Need It. Ready When You Want It.

Stop planning intimacy around a pill. With tadalafil, you're ready when the moment is right, not when the clock says so.

Frequently
asked questions

Find answers to common questions about our medication subscriptions and medical review process.

Is generic tadalafil as effective as Cialis®?

Yes. Generic tadalafil contains the exact same active ingredient in the exact same amounts as brand-name Cialis®. The FDA requires generics to meet identical standards for safety, quality, and effectiveness.

Can I take tadalafil with alcohol?

Moderate alcohol (1-2 drinks) is generally okay, but excessive alcohol can increase side effects like dizziness and may reduce effectiveness. Avoid heavy drinking when using tadalafil.

How quickly does it work?

Tadalafil typically starts working within 30-60 minutes, with peak effectiveness around 2 hours. For the best experience, take it at least 30 minutes before planned activity.

Can I take tadalafil with food?

Yes. Unlike some ED medications, tadalafil can be taken with or without food. High-fat meals may slightly delay absorption, but won't reduce effectiveness.

Will it give me an automatic erection?

No. Tadalafil enhances your natural response to sexual stimulation—it doesn't create arousal. You still need to be sexually stimulated for it to work.
