Nitroglycerin spray while fasting

Fatwaa ID: 2221

Question:
Assalamalaykum
If I had heart/stress testing today and the doctor gave me nitroglycerin sprays under my tongue, does this break my fast?

Answer:
In the Name of Allaah, the Most Gracious, the Most Merciful.
As-salaamu ‘alaykum wa-rahmatullaahi wa-barakaatuh.

May Allaah Ta’aala keep you healthy and safe. A nitroglycerin spray is a sublingual that rapidly diffuses into the blood through the mucous membrane and capillaries beneath the tongue. It does not reach a cavity of consequence directly nor indirectly. Accordingly, nitroglycerin spray under the tongue will not invalidate the fast if administered appropriately. If the medication however is swallowed prior to diffusion, then that would invalidate the fast.

And Allaah Ta’aala knows best.
