Sanofi and Eli Lilly announced plans Wednesday to seek regulatory approval from the U.S. Food and Drug Administration to sell Cialis without a prescription. As they strive to prove that it can be sold safely without a doctor’s guidance, here are some things you might not know about the ED drug.
The hearing loss usually involved only one ear and did not always improve when the medication was stopped. It is not known if the hearing loss was caused by the medication. If you experience a sudden loss of hearing, sometimes with ringing in the ears or dizziness, while you are taking tadalafil, call your doctor immediately. Do not take any more doses of tadalafil or similar medications such as sildenafil (Revatio, Viagra) or vardenafil (Levitra) until you talk to your doctor. Some patients experienced a sudden loss of some or all of their vision after they took tadalafil or other medications that are similar to tadalafil. It is not known if the vision loss was caused by the medication.
Before you start taking Cialis, tell your doctor about any medical conditions you have, especially any heart conditions. You should also tell them about all of the medications you take. They can determine whether Cialis is safe for you based on this information. Blood pressure changes weren’t common in people taking Cialis in clinical trials.

The inhibition of phosphoresce type 5 (PDE5) enhances erectile function by increasing the amount of cGMP.Tadalafil inhibits PDE5. Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 by tadalafil has no effect in the absence of sexual stimulation. If clinically approved, this depends on your personal preference and how frequently you have sex.
Tadalafil can last within the body for 36 hours, so it’s important to avoid taking more than one tablet in a 24-hour time frame.

Taking certain antifungal drugs with tadalafil may increase levels of tadalafil in your blood. This can lead to low blood pressure, dizziness and fainting, and vision problems.

PDE5 inhibitors help to maintain an erection, but they don’t cause the erection. They work by blocking the breakdown of a substance that strengthens the erection. For the medication to work, you still need sexual stimulation, limited stress, healthy hormone levels, and relatively normal blood vessels that can allow for increased blood flow. If the medication doesn’t work, talk to your doctor about alternative or additional treatment options. Both drugs take approximately 30 to 60 minutes to begin working and allow patients to achieve the erection they expect.
Patients on nitroglycerin typically have serious cardiovascular issues that make taking ED medication risky in the first place. Patients taking recreational "poppers," including amyl nitrate, amyl nitrite, and butyl nitrate, should not take ED medication. Speak to your doctor or pharmacist about other drug interactions to ensure safety when taking your ED meds. Alcohol and PDE5 inhibitors, including tadalafil, are mild systemic vasodilators.
