What is Cialis?Cialis, also known as tadalafil, is a prescription medication that's used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). Your body uses Cialis to achieve and maintain an erection by increasing blood flow to the penis.
What is PDE5?Pulmonary hypertension can cause an erection that can last for hours. Cialis can also temporarily decrease the time it takes for the heart to increase blood flow to the penis, making it more difficult to have an erection during sexual activity.
What is Cialis + Dapil?Cialis and Dapil are both tadalafil brands of the medication Cialis. Cialis can be taken daily at a dose of 2.5 mg to 5 mg, depending on your doctor’s prescription. Dapil is taken as needed about 1-2 hours before sexual activity.
Cialis + Dapil has the same active ingredient as Cialis, Tadalafil. Tadalafil can have side effects, but they are not life-threatening. However, they are serious and typically do not require medical attention and should be treated in the same way as Cialis.
Dapil can have interactions with other drugs, including blood thinners, blood pressure medications, and certain antibiotics. Your health care provider can tell you about any of these drugs you are taking.
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.

5.Cimetidine (used to manage anti-diabetic medication): A mettic effect can occur with Cialis, which may result in a reduced effectiveness and increased frequency of side effects.
6.Laminomycin (Ex. chloride creatinine, imidacl magnesium, morphine): Aaminodose interactions can cause reduced blood level of tadalafil, leading to increased risk of side effects.
