Interactions

A. Top Drug-Drug Interactions:

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.

Other Drug-Drug interactions:

  • Ketoconazole, itraconazole (used to manage fungal infection)
  • Protease inhibitors (used to manage HIV infection) Ex. ritonavir, lopinavir
  • Phenobarbital, phenytoin, carbamazepine (medicines used for fits)
  • Rifampicin, erythromycin, clarithromycin (medicines used for bacterial infections)
  • Other medicines used to improve blood flow to the penis (Ex. sildenafil)

B. Drug-Food Interactions:

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:

  1. Grapefruit and Grapefruit Juice: Grapefruit can increase the levels of tadalafil in your blood by interfering with its metabolism. This may amplify side effects, such as headaches, dizziness, or low blood pressure. Avoid consuming grapefruit or grapefruit juice while taking Cialis.
  2. Alcohol: Drinking alcohol with Cialis can enhance the blood pressure-lowering effects of the medication, leading to symptoms like dizziness, lightheadedness, or fainting. Limiting alcohol intake is recommended while using Cialis.
  3. High-Fat Meals: While Cialis can be taken with or without food, consuming it with a high-fat meal may delay its onset of action. Opt for lighter meals if rapid effectiveness is needed.
  4. Caffeine: Though not a direct interaction, combining Cialis with high caffeine intake might worsen side effects like headaches or increase heart rate in sensitive individuals.

  • Alpha-blockers (such as prazosin, tamsulosin) can interact with tadalafil, increasing its blood pressure-lowering effects. This can enhance side effects.
  • Protease inhibitors (such as exemestane, beclidil, vardenafil), including Cialis, can interact with tadalafil, increasing the blood pressure-lowering effects of the medication. This can increase side effects.

  • A new, clinically sound, effective treatment for erectile dysfunction, has been developed for a generic version of Cialis®. The new drug, which has an active ingredient similar to Cialis®, will be manufactured in a lab in Puerto Rico.

    The product is marketed as a combination of tadalafil, a phosphodiesterase-5 (PDE-5) inhibitor, and vardenafil, a selective norepinephrine reuptake inhibitor. Both products contain the same active ingredient, tadalafil, which is used for treating erectile dysfunction (impotence). Tadalafil is the same molecule in both products as it is in Cialis®. Vardenafil is the same molecule in both products as it is in Cialis®.

    The new drug is expected to be of the same strength as Cialis® in its original formulation. It was approved by the U. S. Food and Drug Administration (FDA) in 2003 and marketed in the U. in 2004.

    Cialis®

    The first tablet, Cialis® (5mg tadalafil), was manufactured by Eli Lilly, Inc. In 2003, Lilly acquired the rights to produce Cialis® in Puerto Rico. In 2004, Eli Lilly acquired rights to produce the original Cialis® in the U. It was the first prescription medication to be manufactured and sold in the U. Lilly acquired rights to manufacture the original Cialis® in the U. Lilly acquired a portion of the original Cialis® in the U. in 2007.

    The Cialis® tablets are manufactured in a single strength, which means the product can be used for many different purposes.

    The generic version of Cialis®, tadalafil, has the same active ingredient, and the same strength. The active ingredient in Cialis® is tadalafil, and the inactive ingredients are a chemical called hydroxypropylmethyl cellulose and an aqueous solubility agent called microcrystalline cellulose.

    The product will be marketed as a combination of tadalafil, a phosphodiesterase-5 (PDE-5) inhibitor, and vardenafil, a selective norepinephrine reuptake inhibitor.
