Cialis is a drug used to treat erectile dysfunction. It was approved by the FDA for sale in the United States in 2003. Unlike other erectile dysfunction drugs currently on the market, Cialis comes in two versions. Once version is intended to be used as a once-daily pill, while the other variation is to be taken as needed, and can be taken up to 36 hours in advance. Cialis is available only as a tablet, although similar drugs from other companies also have chewable and dissolvable formats.
