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.

Nitroglycerin

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

Epinephrine's side effects include:

• vomiting
  
• sweating
  
• a headache
  
• pale skin
  
• weakness
  
• nervousness 1

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.

Antivenin

Antivenin is an antidote medication for the poisonous bite of the North American coral snake, according to Drugs.com 2. It belongs to the classification of medicines called immunizing agents.

Antivenin can also cause a fever, swollen glands and joint problems, says Drugs.com 2. Antivenin is given as an injection and its dose depends on the medication strength and severity of the snake bite 2.
