Never combine nitroglycerin and Viagra if you have unstable angina. This condition signifies your heart isn’t receiving enough blood, and combining these medications can severely worsen blood pressure, potentially leading to a heart attack or stroke. Avoid this combination if you’ve recently experienced a heart attack or have a history of severe heart failure. The simultaneous vasodilation caused by both drugs places excessive strain on a weakened heart.
Severe Hypotension: A Critical Warning
Individuals with low blood pressure (hypotension) must absolutely avoid this combination. Both nitroglycerin and Viagra lower blood pressure, and their synergistic effect could cause a dangerous drop, resulting in fainting, dizziness, and even shock. Consult your physician before using either medication if you have a history of hypotension. Carefully monitor your blood pressure regularly if you are prescribed both, and immediately discontinue use if you experience any concerning symptoms.
Aortic stenosis, a narrowing of the aorta, also represents a serious contraindication. The increased blood flow induced by the combination strains the already constricted valve, potentially leading to serious complications. Similarly, patients with severe mitral valve regurgitation, where the mitral valve doesn’t close properly, should avoid this combination to prevent further cardiac stress.
