Nitroglycerin should not be used if a patient is also taking medication to treat which of the following conditions?

• A. High blood pressure
• B. Erectile dysfunction
• C. Heart rhythm disorders
• D. Severe asthma

Answer: (B)

Nitroglycerin is a vasodilator commonly used to relieve chest pain (angina) by dilating blood vessels to improve blood flow to the heart. However, it should not be used in conjunction with medications meant to treat erectile dysfunction, such as sildenafil (Viagra) or tadalafil (Cialis). The reason for this contraindication is that both nitroglycerin and these erectile dysfunction medications can cause significant vasodilation, leading to a dramatic drop in blood pressure. This synergistic effect can result in serious cardiovascular complications, including syncope (fainting) or even heart attack. Therefore, it is crucial for healthcare providers to carefully assess a patient's medications to avoid such dangerous interactions. In contrast, while nitroglycerin can affect blood pressure, it may be cautiously used in patients with high blood pressure, heart rhythm disorders, or severe asthma under professional medical guidance, as these conditions do not inherently pose the same risk of severe adverse reactions that arise when combining nitroglycerin with erectile dysfunction medications.
