Tadalista 5 mg contains tadalafil, a phosphodiesterase type-5 (PDE5) inhibitor used to treat erectile dysfunction and, in some dosing regimens, benign prostatic hyperplasia. Although 5 mg is a relatively low dose, tadalafil can still interact with certain medicines.

The most important interaction is with nitrate medicines, including nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Combining tadalafil with nitrates can cause a significant and potentially dangerous drop in blood pressure. Tadalafil should also not be combined with guanylate cyclase stimulators, such as riociguat.

Tadalafil may enhance the blood-pressure-lowering effects of alpha-blockers and antihypertensive medicines, potentially causing dizziness or fainting. Your healthcare professional may need to consider your blood pressure and medication regimen before recommending tadalafil.

Some medicines that strongly inhibit the CYP3A4 enzyme, such as certain antifungal medicines, HIV medicines, and macrolide antibiotics, can increase tadalafil levels in the body. Depending on the medicine involved, a dosage adjustment may be necessary.

Large amounts of alcohol can also increase dizziness and blood-pressure effects when combined with tadalafil.

Before taking Tadalista 5 mg, tell your doctor or pharmacist about all prescription medicines, over-the-counter products, supplements, and recreational substances you use. Do not start, stop, or change interacting medicines without professional advice.

Seek urgent medical attention for chest pain, severe dizziness or fainting, sudden vision or hearing loss, or an erection lasting longer than four hours.
