Nitroglyn E-R

Do not use nitroglycerin if you are allergic to organic nitrates.

You should not take nitroglycerin if you have the following conditions:

• very recent heart attack
• severe anemia
• increased pressure in the head

Do not take nitroglycerin with drugs for erectile dysfunction, like Viagra (sildenafil citrate), Cialis (tadalafil), or Levitra (vardenafil hydrochloride), as this may lead to extreme lowering of your blood pressure.

• Do not breastfeed. It is not known if nitroglycerin will pass through your milk.
• Do not consume alcohol while taking nitroglycerin, as this can lower your blood pressure.
• Do not start any new prescription or non-prescription medicines or supplements, unless you check with your doctor first.
