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.

VIAGRA is used for the treatment of erectile dysfunction in adult men. Requires a prescription from your doctor before it can be used as a treatment for ED. VIAGRA only works if you are sexually active. Do not use if you: Are allergic to vardenafil or any ingredients in the use vardenafil. Using any medicine does not improve its effect. Using too much or too little will cause side effects and not all medicines work the same. See the end of the CMI for details. VIAGRA is a drug. It is a selective and reversible inhibitor of phosphodiesterase-5 (PDE5). PDE5 breaks down cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis. When there is a lack of cGMP, PDE5 is broken down, allowing more cGMP to accumulate and leading to an erection. By preventing PDE5 from breaking down cGMP, VIAGRA helps cGMP accumulation and improves blood flow to the penis. VIAGRA does not treat erectile dysfunction. It is used for the treatment of erectile dysfunction in adult men. It is a drug. Requires a prescription from your doctor.
