What is Cialis?

Both are approved by the U.S. Food and Drug Administration (FDA) and routinely prescribed for ED. Here, we’ll answer all your questions about tadalafil versus Cialis, starting with: Is tadalafil the same as Cialis? Cialis and tadalafil are basically the same medication, as tadalafil is the active ingredient in Cialis. They’re equally effective in treating erectile dysfunction, last the same amount of time, and carry the same risk of side effects.

7.3 Potential for CIALIS to Affect Other Drugs

The main difference is that Cialis is a brand name, which usually makes it more expensive than its generic version, tadalafil. Both tadalafil and Cialis belong to a class of drugs called phosphodiesterase 5 inhibitors (PDE5 inhibitors), which were initially developed to treat hypertension (high blood pressure). These drugs block the PDE5 enzyme, widening blood vessels and improving blood flow to the penis with sexual stimulation. This results in firmer, longer-lasting erections, no matter what’s causing ED symptoms. After all, many factors contribute to erectile dysfunction, including: Tadalafil and Cialis are ED pills that can be taken daily or just before sex to improve erectile function, regardless of whether your ED is mental or physical. Daily Cialis and as-needed tadalafil before sex are similarly effective for treating ED, according to a 2017 review. If you’re wondering about differences in effectiveness between tadalafil and Cialis, there are none. Since their chemical content is identical, any study on the efficacy of tadalafil can also be considered a study on Cialis. That’s because generic medications are required to be the same as their brand-name drugs in dosage, efficacy, strength, and safety, as well as how the medication is taken. Put simply, one of the biggest differences between Cialis and tadalafil is branding.

Be ready for sex whenever you're in the mood Dealing with erectile dysfunction (ED) can be, well, hard — just ask the 30 million affected men in the United States. But choosing the right treatment can be even harder, which brings us to tadalafil versus Cialis®. If you’ve been exploring ED medications, you’ve likely come across Cialis and the generic drug tadalafil. Two names exist because Cialis is a trademark of the drug manufacturer Eli Lilly and Company. Though tadalafil was approved by the FDA in 2003 and sold exclusively as Cialis by Eli Lilly, the patent expired in 2018. This allowed other companies to begin selling the generic drug. As of 2024, neither tadalafil nor Cialis is available as an over-the-counter drug. Whether you take the brand-name medication or the generic version, your dosage will be the same. Treating ED and treating benign prostatic hyperplasia require different tadalafil dosages. For BPH, tadalafil is prescribed at a daily lower dose of 5 milligrams (mg). A higher Cialis dosage — usually 10 milligrams — is used for the treatment of erectile dysfunction as needed before sex. A 20-milligram Cialis dose can also be used as needed for erectile dysfunction. A daily 5 milligram dose can be used for erectile dysfunction for guys with more frequent or more spontaneous needs.

Understanding Tadalafil

Do not use any of the following with tadalafil or within 48 hours of your last dose of tadalafil: certain drugs used to treat chest pain/angina (nitrates such as nitroglycerin, isosorbide) recreational drugs called "poppers" containing amyl or butyl nitrite If you are also taking an alpha blocker medication (such as doxazosin, tamsulosin) to treat an enlarged prostate/BPH or high blood pressure, your blood pressure may get too low which can lead to dizziness or fainting. Your doctor may start treatment with a lower dose of tadalafil or adjust your alpha blocker medication to minimize your risk of low blood pressure. Other medications can affect the removal of tadalafil from your body, which may affect how tadalafil works. Examples include azole antifungals (such as itraconazole, ketoconazole), macrolide antibiotics (such as clarithromycin, erythromycin), HIV protease inhibitors (such as fosamprenavir), rifampin, ritonavir, among others. Do not take this medication with any other product that contains tadalafil or other similar medications used to treat erectile dysfunction-ED or pulmonary hypertension (such as sildenafil, vardenafil).
