Cialis: What It Is, How It Works, and What Alternatives You Should Know

When you hear Cialis, a prescription medication used to treat erectile dysfunction by increasing blood flow to the penis. Also known as tadalafil, it's one of the most common ED drugs used today because it lasts up to 36 hours — longer than most others. Unlike quick-acting pills, Cialis gives you flexibility. You don’t need to time it right before sex. It works when you’re ready, not when the clock says so.

But Cialis isn’t the only option. tadalafil, the active ingredient in Cialis is also sold as a generic, which many people choose to save money. Other ED treatments like Levitra, a brand name for vardenafil, another PDE5 inhibitor work faster but don’t last as long. Then there’s Viagra, the original ED pill, with sildenafil as its active ingredient — effective, but you usually need to take it on an empty stomach and wait about an hour. Cialis stands out because it’s less affected by food and lasts longer, making it a favorite for men who want spontaneity.

People use Cialis for more than just erections. Doctors sometimes prescribe it off-label for benign prostatic hyperplasia (BPH), a condition that causes trouble urinating. It helps relax muscles in the prostate and bladder, making it easier to go. That’s why some men take it daily in low doses — not just for sex, but for daily comfort. If you’re on blood pressure meds, heart drugs, or nitrates, talk to your doctor first. Mixing Cialis with these can drop your blood pressure too low.
