Cialis: What It Is, How It Works, and What You Need to 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 commonly prescribed options for men looking for reliable, long-lasting results. Unlike some other ED drugs that last only a few hours, Cialis can work for up to 36 hours—earning it the nickname "the weekend pill." That doesn’t mean you take it every weekend, but it does mean you have more flexibility in timing. It’s not a magic fix—it works when you’re sexually stimulated—but it removes a lot of the pressure that comes with waiting for a quick reaction.
Cialis belongs to a class of drugs called PDE5 inhibitors, which also includes Viagra (sildenafil) and Levitra (vardenafil). These all do the same basic job: they relax muscles in the penis so blood can flow in and create an erection. But Cialis stands out because of how long it lasts and how it can be taken daily in low doses for ongoing support. If you’re dealing with ED regularly, the daily version might be simpler than planning ahead. It’s also used to treat symptoms of an enlarged prostate, which is why some men get it for two reasons at once. But it’s not for everyone. If you take nitrates for chest pain, or have serious heart issues, liver or kidney disease, or low blood pressure, Cialis can be dangerous. Always talk to your doctor before starting.
People often confuse side effects with allergies. With Cialis, common side effects include headache, upset stomach, back pain, or muscle aches—usually mild and temporary. A true allergic reaction—like swelling of the face or trouble breathing—is rare but serious. And while some online stores sell cheap versions, many are fake or contain harmful ingredients. The FDA has warned about counterfeit Cialis sold online that includes dangerous substances like methamphetamine or printer ink. Stick to licensed pharmacies. You’re not saving money if you risk your health.
