36-hours Cialis is an FDA-approved medication used to treat erectile dysfunction. You can take 36-hour Cialis on an as-needed basis about 30 minutes before sexual activity.

Cialis is a prescription medication, so you must make an appointment with a licensed healthcare professional to obtain the drug. One option is to contact a reputable, USA-based online pharmacy to get a prescription for Cialis, since a few online pharmacies offer medical evaluations with US-licensed doctors. It’s a convenient option for men who don’t want to take time off work to see their doctor in person.

Beware of websites selling “generic” versions of Cialis. Currently, the FDA has not approved the generic form of Cialis, so it is illegal in the United States. Plus, these counterfeit medications can be dangerous to your health. When choosing an online pharmacy, do your research and choose a website you can trust.
