Questions about Viagra and Cialis
Below, you’ll find answers to some common questions about Viagra and Cialis.
How does Viagra or Cialis compare with Levitra?
Like Viagra and Cialis, Levitra is an oral tablet approved to treat ED in adults. But brand-name Levitra is no longer available. The generic version of Levitra, vardenafil oral tablet, is available. Viagra, Cialis, and vardenafil have some similarities and differences:
- Viagra and vardenafil are only approved to treat ED. Cialis is also approved to treat the symptoms of BPH.
- Viagra, Cialis, and vardenafil all belong to a group of drugs known as phosphodiesterase 5 (PDE5) inhibitors. They all work in a similar way to treat ED and they have similar side effects and warnings.
- The dosages of Viagra, Cialis, and vardenafil are different. Viagra or vardenafil are taken about 1 hour before sexual activity. But Viagra may be taken 30 minutes to 4 hours before sexual activity. Vardenafil doesn’t have this dosing flexibility. When Cialis is taken as needed, it may be taken any time before sexual activity.
- The costs of Viagra, Cialis, and vardenafil may differ, especially since vardenafil is a generic drug. Generic drugs usually cost less than brand-name drugs.
Talk with your doctor or pharmacist if you have questions about how Viagra, Cialis, and vardenafil compare.
