Do not take sildenafil (e.g., Viagra) if you are taking this medicine. When sildenafil is taken with amyl nitrite, the combination can lower blood pressure and cause dizziness, lightheadedness, or fainting. In some cases, sildenafil taken with the related nitrates has caused death.
Amyl nitrite is extremely flammable. Keep it away from heat or any open flame, especially when crushing the capsule. Amyl nitrite can catch fire very easily and cause serious burns.
Dizziness or lightheadedness may occur, especially when you get up from a lying or sitting position. Getting up slowly may help, but if the problem continues or gets worse, check with your doctor.
Drinking alcohol while you are taking this medicine may make the dizziness or lightheadedness worse and may cause a serious drop in blood pressure. Check with your doctor before drinking alcoholic beverages.
After using a dose of amyl nitrite, you may get a mild headache that lasts for a short time. This is a common side effect and is no cause for alarm. However, if this effect continues, or if the headaches are severe, check with your doctor.
