List of Emergency Drugs

Unfortunately, emergencies arise when least expected. People can suddenly suffer a heart attack or have an anaphylactic reaction (severe allergic reaction) after consuming certain foods. In some cases, emergency situations arise when poisonous snakes attack. Fortunately, emergency medications exist to manage such dire medical scenarios.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.


Nitroglycerin is a medication used to treat sudden onset of chest pain, also known as angina. During angina, inadequate amounts of oxygen and blood reach the heart. Death of heart tissues may occur if this is prolonged enough, which then becomes a heart attack.

The National Library of Medicine says that nitroglycerin relaxes the smooth muscle in blood vessels to allow more blood to flow to the heart. Nitroglycerin's side effects include a headache, intermittent lightheadedness, fainting and low blood pressure.

Nitroglycerin should not be taken with such phosphodiesterase medications such as sildenafil as the combination can cause blood pressure to plummet. Nitroglycerin is available as an ointment, spray or patch that must be taken as physicians indicate.


Epinephrine's side effects include:

  • vomiting
  • sweating
  • a headache
  • pale skin
  • weakness

Dizziness, tremors, stomach problems, vomiting and sweating are epinephrine's other side effects 1. Epinephrine's serious effects include trouble breathing and a fast or irregular heartbeat, says MedlinePlus 1.
