Select Important Safety Information

Do not take CIALIS if you:

  • take medicine called "nitrates" such as isosorbide dinitrate or isosorbide mononitrate which are often prescribed for chest pain, or use recreational drugs called "poppers" like amyl or butyl nitrite, as the combination may cause an unsafe drop in blood pressure
  • are allergic to CIALIS or ADCIRCA® (tadalafil), or any of its ingredients. Call your healthcare provider or get help right away if you experience any symptoms of an allergic reaction, such as rash, hives, swelling of the lips, tongue or throat, or difficulty breathing or swallowing.

After taking a single tablet, some of the active ingredient of CIALIS remains in your body for more than 2 days. It can remain longer if you have problems with your kidneys or liver, or you are taking certain other medications.

Stop sexual activity and get medical help right away if you get symptoms such as chest pain, dizziness, or nausea during sex.

Beware of Counterfeit CIALIS

CIALIS is available only with a prescription from your doctor.
The only way to be sure you’re getting real CIALIS is by getting a prescription from your doctor and taking it to your local pharmacy or a certified online pharmacy to have it filled. If you want to be ready anytime the moment is right, be sure to purchase CIALIS from a reliable pharmacy. And remember, prescriptions can only be filled at U.S.-based pharmacies.

If you do prefer to purchase CIALIS online, here are some ways to help make sure you’re getting the real thing. Beware of sites that:

  • Offer CIALIS at a price that’s much lower than the price at your local pharmacy or at a price that seems “too good to be true”
  • Don’t list a street address or contact information, especially if they’re not located in the United States
  • Sell prescription medications without a prescription, or after a short online survey or review by a remotely located physician
  • Offer generic, “soft tab,” or “fast dissolve” CIALIS. There is no generic for CIALIS, and CIALIS only comes as an almond-shaped tablet that is swallowed whole.

Only use online pharmacies that are accredited by the National Association of Boards of Pharmacy (NABP).

It is difficult to tell whether or not the ED drugs you purchase online are dangerous because counterfeiters are very good at copying the packaging and appearance of legitimate ED drugs. Even the makers of legitimate ED drugs often can’t confirm whether or not a product bought online is real until they’ve conducted chemical analyses.

More than 50% of drugs bought online from illegal sites are counterfeit, so don’t buy CIALIS from Web sites that offer to sell it to you without a prescription. The drugs they sell may be counterfeit (fake), illegal, and possibly dangerous. To minimize your chances of getting fake CIALIS, make sure your prescription is filled at a U.S.-based or accredited online pharmacy. Online pharmacies with Verified Internet Pharmacy Practice Sites™ (VIPPS) accreditation have had their facilities inspected and their practices reviewed by the NABP.
