1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
Similar to gramena, interferes with the absorption of tadalafil, rendering it non-EIB! This may cause symptoms like dizziness, lightheadedness, or fainting.

FDA-sponsored News Release
Wednesday, July 15, 2002
NEW YORK (The New York Times) -- The Food and Drug Administration on Tuesday announced it is approving a generic version of the erectile dysfunction drug Viagra, which is expected to become the first oral-only drug for the treatment of erectile dysfunction.
The agency's announcement comes as drug makers are increasingly testing new formulations of Viagra, a treatment for enlarged prostate glands.
"Our new formulation of Viagra, Cialis, is expected to be in early, sooner than anticipated," said Acting FDA Commissioner Lester Crawford. "It is a new medication for men with erectile dysfunction who are experiencing the symptoms of benign prostatic hyperplasia and who need to be given the medication before they go on to treatment."
The FDA has approved the first generic formulation of Cialis. The drug's patent expires on Jan. 31, 2002. The drug's active ingredient is Viagra, which was first approved in the United States by the Food and Drug Administration in October, in the United States by the FDA in June.
The drug has been approved for the treatment of erectile dysfunction in men only. For men, it is available as a 10 mg, 25 mg, and 50 mg oral tablet.
In a letter posted on the FDA website, Dr. Michael E. Anagnosti, director of the agency's Center for Drug Evaluation and Research, said "We are pleased to have approved Cialis."
FDA spokeswoman Julie Lefkowitz said, "This approval represents an important milestone in the ongoing efforts of the FDA to evaluate and approve drugs to treat ED, and the FDA is pleased that our agency has conducted an extensive review of the product to ensure safety and efficacy."
Cialis, marketed by Eli Lilly and Company, is one of several approved drugs for treating erectile dysfunction. Cialis has also been approved for treatment of benign prostatic hyperplasia, and was approved for treatment of prostate cancer in 2002, according to the FDA.
A number of men suffering from ED and their partners had reported difficulty conceiving due to difficulty conceiving due to erectile dysfunction. Cialis works by allowing the body to produce more blood and blood flow to the penis. It is available in 10 mg, 25 mg, and 50 mg oral tablets and is usually taken one to three times a day, about 30 minutes before intercourse.
Viagra is a generic drug and does not have any competition from Cialis. The patent for Viagra expires on July 31, 2002, and other generic versions of the drug may soon be available. Cialis is also a treatment for benign prostatic hyperplasia, or BPH.
A spokeswoman for Pfizer, the pharmaceutical company that manufactures Cialis, said, "We are pleased to have approved Cialis. The drug has been approved for the treatment of ED in men only. We are pleased that the FDA has approved it for the treatment of BPH."
Cialis is also being developed and is being tested in large clinical trials in patients with erectile dysfunction, which includes the disorder. Anagnosti said the drug is in Phase III trials. It is available for purchase at pharmacies and through mail order from Eli Lilly and Company.
Anagnosti said the drug will be available as an oral tablet by mail or by a generic manufacturer at pharmacies and through mail order in January. Cialis is also available at Walgreens. The company will also be available for the first time in a 30-milligram strength form of the tablet, which is sold in the U. S. as Viagra. Pfizer, which manufactures Cialis, and other drugmakers, has already approved the drug for use as an oral tablet.
Dr. Michael Anagnosti, director of the agency's Center for Drug Evaluation and Research, said, "We are pleased to have approved Cialis. We are pleased that the FDA has approved it for the treatment of BPH. Cialis is a treatment for BPH and is used to treat men with ED who are at a greater risk for BPH."
