Top PALS Medications You Must Know
  • Updated on: March 5, 2026

 

In a pediatric emergency, there is no time to stop and look something up. Every decision matters — especially when it comes to PALS medications. The drugs used during Pediatric Advanced Life Support (PALS) are designed for critical moments like cardiac arrest, respiratory failure, and shock. Using them correctly can make the difference between life and death.

The goal is simple: know what each drug does, when to use it, and the most important things to remember when you’re under stress. Healthcare providers can act more quickly and confidently when it matters most if they know the right medications ahead of time. This guide is all about the most important medicines for people with PALS.

What Is PALS and Why Medications Matter

The Pediatric Advanced Life Support (PALS) training program prepares healthcare providers to respond to serious emergencies in infants and children. It focuses on conditions such as cardiac arrest, respiratory failure, and shock, which require quick, skilled action.

PALS follows a set of guidelines to assist providers in patient assessment, airway management, breathing and circulation support, and rapid decision-making. One important aspect of this process is taking the right medications at the right time.

Medications in PALS are not used randomly — each one has a specific purpose. Some revive the heart. Others reduce swelling in the airway, raise blood pressure, or help stabilize an irregular heart rhythm. But knowing what to give and when to give it isn’t always easy under pressure.

Top 10 PALS Medications and Their Uses

In pediatric emergencies, there’s no room for guessing. This section breaks down the 10 most important emergency pediatric medications for students preparing for the PALS course or real-world emergencies.

1. Epinephrine

Epinephrine is the most commonly used pediatric resuscitation drugs in cardiac arrest situations. It stimulates the heart and increases blood flow to vital organs.

Why it matters:

  • Increases heart rate and blood pressure
  • Helps restart the heart during Cardiopulmonary Resuscitation (CPR)
  • Treats severe allergic reactions and some cases of bradycardia
  • Route: Intravenous (IV), Intraosseous (IO) for cardiac arrest; Intramuscular (IM) for anaphylaxis

2. Amiodarone

Amiodarone is used for life-threatening arrhythmias, especially when defibrillation isn’t working.

Why it matters:

  • Helps slow down or stop abnormal fast rhythms
  • Used when the heart is beating too fast or irregularly
  • Route: IV or IO

3. Adenosine

Adenosine is used for very fast heart rhythms coming from the upper part of the heart, like SVT (supraventricular tachycardia).

Why it matters:

  • Temporarily stops the heart’s electrical activity to reset the rhythm
  • Helps diagnose and treat SVT quickly
  • Route: Rapid IV push followed immediately by saline flush

4. Atropine

Atropine helps treat slow heart rates, especially when caused by certain toxins or high vagal tone.

Why it matters:

  • Blocks signals that slow the heart, causing it to beat faster.
  • Suitable for bradycardia that does not respond to oxygen or ventilation.
  • Route: IV or IO

5. Magnesium Sulfate

Magnesium sulfate is used to treat torsades de pointes, an abnormal heart rhythm, as well as to correct magnesium deficiency.

Why it matters:

  • Stabilizes heart rhythm in torsades
  • Helps relax muscles and nerves
  • Route: IV or IO

6. Sodium Bicarbonate

Sodium bicarbonate balances acid-base levels and is used in severe cases such as drug overdoses or acidosis.

Why this matters:

  • Raises blood pH in metabolic acidosis
  • It can help protect the heart in high potassium situations
  • Route: IV or IO

7. Dextrose (D10, D25, D50)

Dextrose is used to treat hypoglycemia, or low blood sugar. In children, this can lead to seizures or passing out.

Why it matters:

  • Gives the brain and body quick energy.
  • Stops low glucose levels from hurting the brain
  • Route: IV or IO (the concentration depends on how old the patient is)

8. Narcan (Naloxone)

Naloxone reverses the effects of opioid overdose, such as slowing or stopping breathing.

Why it matters:

  • Rapidly restores breathing in opioid toxicity.
  • Safe and effective, even without a confirmed diagnosis. Available routes include IV, IO, IM, and intranasal.

9. Calcium (Chloride, Gluconate)

Calcium is given when potassium levels are high, calcium levels are low, or in the event of an overdose, such as calcium channel blockers.

Why it matters:

  • Helps the heart and muscles to contract.
  • Helps to keep the heart stable when there are dangerous electrolyte imbalances in the body.
  • Route: IV or IO (in emergencies, chloride is preferred; gluconate is better for veins)

10. Lidocaine

Lidocaine is an alternative to amiodarone for treating life-threatening ventricular arrhythmias.

Why it matters:

  • Slows down abnormal electrical signals in the heart
  • May be used if amiodarone is unavailable or not working
  • Route: IV or IO

Memory Tricks for PALS Drugs

Memorizing PALS medications can be difficult, especially when trying to recall them quickly during high-stress paediatric emergencies. Fortunately, there are effective memory tricks, mnemonics, and practice techniques to help you remember the most important drugs—as well as how to administer them. Learning PALS pharmacology focuses on drug names, doses, and routes. Here’s how to make it easier:

1. Use Mnemonics for Core Drug Functions

Mnemonics are effective tools for memorizing drug categories and their functions. One frequently used for PALS medications is:

“Every Awesome And Attentive Medic Can Save Lives Now”

Each word represents a key drug:

  • Epinephrine: for cardiac arrest, anaphylaxis
  • Amiodarone: for shockable rhythms
  • Adenosine: for Supraventricular Tachycardia (SVT)
  • Atropine: for bradycardia
  • Magnesium sulfate: for Torsades de Pointes
  • Calcium chloride: for calcium channel blocker overdose
  • Sodium bicarbonate: for acidosis
  • Lidocaine: antiarrhythmic
  • Naloxone: for opioid overdose

2. Associate Drugs with Clinical Scenarios

In paediatrics, epinephrine is always used as the first line of treatment.

Adenosine causes SVT in otherwise healthy children.

  • Atropine: Slow heart rate, unresponsive to oxygen.
  • Creating mental flashcards for “If X happens, use Y” improves recall under pressure.

3. Practice with Flashcards or Apps

Test yourself on a regular basis with digital flashcard tools like Anki or Quizlet.

  • Drug names
  • Indications
  • Doses and repeat intervals
  • Mobile PALS review apps also offer interactive learning formats.

4. Repeat With Simulation or Peer Quizzing

Team-based drills and practice scenarios help to reinforce drug selection in context. Set up timed simulations to improve recall speed.

Common Errors with PALS Medications

Pediatric Advanced Life Support (PALS) requires not only fast action but also precise decision-making — especially when it comes to medications. In high-stress situations like cardiac arrest or severe bradycardia, medication errors can delay treatment, reduce effectiveness, or even cause harm.

Whether during simulation or real-life code situations, certain mistakes with drug dosing, timing, and administration routes occur repeatedly. Recognizing these common pitfalls is critical to improving team performance and patient safety.

The most common medication-related errors observed in PALS are listed below, along with tips for preventing them.

1. Incorrect Dosing

Pediatric medication dosing is weight-based, which complicates emergency situations. The most common error is administering an adult dose or miscalculating the correct milligram or milliliter amount.

How to Avoid It:

  • Always calculate PALS drug doses based on the child’s weight in kilograms.
  • Use the Broselow tape or a pediatric dosing chart.
  • Double-check conversions, especially with drugs like epinephrine and dextrose.

2. Wrong Route of Administration

Certain drugs must be given via a specific route to be effective. For example, adenosine must be administered rapidly through IV with a flush, while epinephrine may be given IV, IO, or IM depending on the scenario.

How to Avoid It:

  • Know which routes are appropriate for each drug in each situation.
  • Label lines clearly and verify access before administration.

3. Delayed Medication Delivery

In cardiac arrest, timing matters. Delays in giving epinephrine or antiarrhythmic medications can lower survival rates.

How to Avoid It:

  • To avoid this, assign clear roles during resuscitation to ensure proper drug preparation and delivery.
  • Prepare medications in advance, especially during CPR cycles.

4. Repeating Doses Too Soon

Giving a second dose of epinephrine, adenosine, or other medications too soon may disrupt the treatment plan and cause side effects.

How To Avoid It:

  • Follow the timing guidelines precisely (e.g., epinephrine every 3-5 minutes in cardiac arrest).
  • Use a timer or assign someone to keep track of medication intervals.

5. Confusing Similar-Sounding Drugs

Drugs like amiodarone and atropine can be confused under pressure due to similar names or packaging. This can result in the wrong drug being drawn up or given.

How To Avoid It:

  • Use closed-loop communication when ordering and confirming medications.
  • Read labels out loud before administration.

FAQs

1. What is the most important drug in PALS?

Epinephrine is the most important medication in PALS. It treats cardiac arrest, bradycardia, and anaphylaxis. It increases blood flow to the heart and brain during CPR, which aids in circulation restoration. Epinephrine is the first-line treatment for asystole and pulseless electrical activity (PEA), administered every 3-5 minutes.

2. How is epinephrine dosed in pediatric cardiac arrest?

In cases of pediatric cardiac arrest, epinephrine is given at a concentration of 1:10,000, or 0.1 mL/kg. It is given through an IV or IO every 3 to 5 minutes during CPR. Proper dosing is very important, and it should always be based on weight. Each dose should be followed by a flush to make sure that the medicine gets into the bloodstream.

3. What are the differences between PALS and ACLS medications?

Both PALS and ACLS use core drugs like epinephrine and amiodarone, but PALS uses weight-based dosing and adds pediatric-specific drugs like dextrose, calcium, and naloxone. ACLS uses fixed adult doses and focuses on coronary events. PALS focuses on reversible causes and developmental considerations for pediatric patients.

4. Is atropine still used in PALS algorithms?

Yes, atropine is still part of PALS but is used selectively. It’s not the first choice for bradycardia unless the cause is increased vagal tone or certain toxic exposures. The pediatric dose is 0.02 mg/kg IV/IO, with a minimum of 0.1 mg and specific repeat limits.

5. What’s the best way to memorize PALS medications?

Utilize mnemonics, clinical scenarios, and repetition. Link each drug to its most common use (for example, adenosine for SVT). Drug names are easier to remember when abbreviated as EAAAM-BD-NCL. Use flashcards, mock codes, and spaced repetition apps to improve memory under pressure. The clinical context enhances long-term retention.
