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:
Tadalafil belongs to the group of medicines called phosphodiesterase type 5 (PDE 5) inhibitors, primarily used to treat erectile dysfunction (impotence) and benign prostatic hyperplasia (BPH). Erectile dysfunction is the inability to keep a hard and erect penis suitable for sexual activity. Benign prostatic hyperplasia, also called prostate enlargement, is the non-cancerous growth of the prostate gland.
Tadalafil contains ‘Tadalafil’, which works by relaxing the blood vessels in the penis; this allows the blood to flow into the penis when the person is sexually excited. Thereby, it helps to treat erectile dysfunction. Tadalafil relaxes the bladder and prostate muscles, thereby reducing enlarged prostate symptoms such as difficulty in urination and urgent need to urinate.
You are advised to take Tadalafil for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects, such as headache, back pain, muscle pain, pain in the legs and arms, nasal congestion, indigestion, and facial flushing. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
