Meet tadalafil

  • The more affordable, generic version of Cialis
  • Flexible dosage options
  • Taken daily or as-needed for spontaneous sex

How to take it

Always take tadalafil as instructed by your healthcare provider. Tadalafil can be taken as-needed or daily. Tadalafil usually starts to work within 30 to 60 minutes, and its effects can last for between 24 and 36 hours, so it can support erections longer than other prescription ED treatments. Tadalafil is triggered by sexual stimulation, so you need to be aroused for it to work.

Common tadalafil side effects

Potential side effects can include headaches, flushing, upset stomach, abnormal vision, runny or stuffy nose, back and muscle pain, nausea, dizziness, and rash. In rare cases, it can cause changes in vision or loss of sight. If you have any side effects that bother you or do not go away, talk to your provider. Do not drink alcohol to excess (more than five drinks) while taking this medication.

Prescription products require an online consultation with a physician who will determine if a prescription is appropriate.

Why tadalafil?

While it has the same active ingredient as branded Cialis®, tadalafil (the generic version of Cialis) is about 95% cheaper.

Tadalafil can be taken daily or as-needed to help men achieve optimal erectile function. It’s good for guys who want to be ready anytime the mood strikes.

Inhibits PDE5

Tadalafil works by suppressing an enzyme called phosphodiesterase type 5 (PDE5).

Boosts blood flow

When PDE5 is suppressed, blood is able to move more freely to the penis.

Gets you hard

More blood flow allows for harder, longer-lasting erections with sexual stimulation.

Frequently asked questions about tadalafil

What is generic Cialis?

Tadalafil is the generic form of “name brand” Cialis. It’s used to treat erectile dysfunction.

How does tadalafil work?

Tadalafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.

Is tadalafil (generic Cialis) stronger than sildenafil (generic Viagra)?

While both medications help men achieve satisfactory erections, the effects of tadalafil last longer than the effects of sildenafil.
