What are the contraindications for taking cialis?

See the DrugPatentWatch profile for cialis

Who Should Not Take Cialis?

Cialis (tadalafil) is contraindicated in patients using nitrates (e.g., nitroglycerin) or nitric oxide donors, as this combination can cause severe hypotension.[1] It is also contraindicated in those with known hypersensitivity to tadalafil or any Cialis component.[1]

Why Avoid Nitrates with Cialis?

Nitrates and Cialis both increase cyclic guanosine monophosphate (cGMP) levels, leading to excessive vasodilation and potentially life-threatening blood pressure drops. This applies to all forms of nitrates, including recreational amyl nitrite ("poppers").[1][2]

Heart Conditions That Rule Out Cialis

Do not use Cialis in patients with recent myocardial infarction (within 90 days), unstable angina, severe hypotension (<90/50 mmHg), uncontrolled hypertension (>170/100 mmHg), or New York Heart Association Class 2+ heart failure.[1] These increase risks of cardiovascular events during sexual activity.[2]

Eye and Vision Issues

Cialis is contraindicated in those with hereditary degenerative retinal disorders like retinitis pigmentosa, due to potential retinal toxicity from PDE5 inhibition.[1]

Other Key Restrictions

Avoid in patients with severe hepatic impairment (Child-Pugh Class C) or end-stage renal disease on dialysis, as tadalafil exposure rises significantly.[1] It is also not recommended during riociguat therapy for pulmonary hypertension, due to amplified hypotensive effects.[1]
