What are the Differences Between Cialis 36-Hour and Daily Cialis

Cialis was the third of the “big three” erectile dysfunction medications to enter the market, making its debut in 2003. But Cialis wasn’t just an also-ran: in a way, it revolutionized the treatment of erectile dysfunction all over again due to its significantly longer half-life than competitors Levitra and Viagra.

Cialis had something more to offer than its competitors for men with erectile dysfunction.

With a half-life of around 18 hours (compared to 4 to 6 hours for its competitors), a man could take Cialis on a Friday night, and possibly still feel the drug’s effects on Sunday. Cialis, quite naturally, capitalized on this, nicknaming it the “Weekend Pill,” indicating users of the drug could get a weekend’s worth of sexual intimacy from a single Cialis pill.

Sure, the company took some grief over its iconic couple of side-by-side bathtubs watching the sunset, but they laughed all the way to the bank. Cialis became the top-selling erectile dysfunction drug, and even in 2017, on the brink of losing patent protection in the United States and Europe, it remains a blockbuster drug (defined as a drug that brings in $1 billion or more per year in revenue).

Several years ago, Cialis started offering the option of daily Cialis therapy. Instead of taking 5 mg, 10 mg, or 20 mg of Cialis on an as-needed basis, men could take 2.5 mg to 5 mg of Cialis at approximately the same time every day, with the goal being a steady enough level of the drug that sexual spontaneity becomes a real possibility. Here are some frequently asked questions about Cialis daily therapy versus Cialis taken on the traditional as-needed basis.
