Amyl nitrite can cause serious harmful effects if too much is inhaled.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. Tell your doctor if you have ever had any unusual or allergic reaction to amyl nitrite or nitrates. Also tell your health care professional if you are allergic to any other substances, such as foods or dyes. Studies on effects in pregnancy have not been done in either humans or animals.
