Are there any specific medications that I should avoid if I am on nitroglycerin?

You should not take sildenafil if you are taking nitroglycerin. Taking these two medicines together can cause an excessive fall in blood pressure, which may even be life-threatening. Along with this, avoid taking other medicines which belong to the same class such as vardenafil and tadalafil.

I noticed that I started to have terrible headaches after taking nitroglycerin. Should I stop?

No, do not stop medication on your own. nitroglycerin may cause headaches during the initial phase of treatment, and this may gradually become less severe and go away as you persist with your treatment. Inform your doctor if the headaches do not go away.

Information About Nitroglycerin

Nitroglycerin is an organic nitrate vasodilator used to treat and prevent acute angina pectoris and acute heart failure in Singapore. Available as a 300mcg–500mcg sublingual tablet or spray for acute angina or as a transdermal patch for prophylaxis, it is HSA-registered and available on prescription only in Singapore. Concurrent use with PDE5 inhibitors including sildenafil and tadalafil is strictly contraindicated as the combination produces a severe and potentially fatal synergistic drop in blood pressure through additive cGMP-mediated vasodilation. A valid doctor's consultation is required before dispensing. Order Nitroglycerin online at DoctorOnCall Singapore with same-day delivery available.
