Phenothiazines
Combining nitroglycerin tablets with a phenothiazine medication may cause dangerously low blood pressure. Your blood pressure may need to be closely monitored if you take these medications together.
 
Phosphodiesterase Type-5 (PDE5) Inhibitors
If you are using nitroglycerin tablets, you cannot take a PDE5 inhibitor, as dangerously low blood pressure may result. You cannot take these medications even within a few days of each other.
 
Rosiglitazone
One study has suggested that people taking rosiglitazone with a nitrate, including nitroglycerin tablets, might have an increased risk for poor blood flow to the heart, which may lead to a heart attack.
