Cialis is a prescription-only medication.
If you encounter any over-the-counter supplements claiming to contain tadalafil, the active ingredient in Cialis, you should avoid taking them. These products aren’t regulated by the FDA and could be counterfeit.
You should also avoid online pharmacies that are offering Cialis without a prescription.
You can also try GoodRx for Erectile Dysfunction, which offers personalized recommendations from licensed providers and home delivery of clinically-proven treatments, like sildenafil (generic Viagra) and tadalafil (generic Cialis).
