Emergency Drugs Quick Guide - Adult Doses, Indications & Ward Checklist
Read this first - key safety rules
Confirm patient identity and weight when possible. Always follow local protocols and resus team instructions. For paediatric dosing and infusions use standard pediatric guides, not this adult sheet.
The quick sheet below is for emergency ward use and exam revision. It is not a replacement for your hospital drug chart or a pharmacy consult.
How this guide is organised
Each entry lists the common adult indication, a typical IV or IM emergency dose and one quick clinical note. The PDF is printable and formatted for a single A4 page so you can keep it on the trolley or phone.
Top emergency drugs - snapshot table
| Drug | Indication | Usual adult dose | Quick notes |
|---|---|---|---|
| Adrenaline | Cardiac arrest; anaphylaxis | Arrest: 1 mg IV every 3-5 min. Anaphylaxis: 0.5 mg IM. | In arrest give IV; for anaphylaxis give IM and call for help. |
| Atropine | Symptomatic bradycardia | 500 mcg IV bolus, repeat q3-5 min to max 3 mg | If ineffective consider pacing; check cause. |
| Amiodarone | VF/VT arrest | 300 mg IV bolus, second dose 150 mg | Monitor blood pressure and QT; use per ACLS guidance. |
| Adenosine | Regular narrow-complex SVT | 6 mg rapid IV bolus, then 12 mg if needed | Give via large-bore IV with saline flush; contraindicated in pre-excited AF. |
| Naloxone | Opioid overdose | 0.4-2 mg IV/IM, repeat as needed | Titrate to restore respiration; may precipitate withdrawal. |
| Calcium gluconate | Hyperkalaemia with ECG changes | 10 mL of 10% IV over 2-5 min | Stabilises myocardium but does not lower K. |
| Insulin + Dextrose | Hyperkalaemia shifting therapy | Insulin 10 units IV + 25 g dextrose | Monitor glucose and arrange K removal therapy. |
| Magnesium sulphate | Torsades de pointes; severe asthma | Torsades: 2 g IV bolus | Check renal function; monitor for hypotension. |
| Tranexamic acid | Major haemorrhage | 1 g IV over 10 min, then 1 g over 8 hrs if indicated | Give early in trauma or postpartum haemorrhage per protocol. |
| Aspirin | Suspected acute coronary syndrome | 300 mg oral chewable immediately | Unless contraindicated; part of initial ACS pathway. |
Practical usage notes
- Always check allergies and recent drug chart entries before giving any drug.
- For repeated boluses and infusions check local infusion concentrations and syringe pump protocols.
- Where IV access is poor, consider intraosseous access per local resus protocol.
- Document time, dose and route immediately after giving, and handover to the receiving team.
Quick decision checklist for the trolley
- Is the patient breathing and perfusing? Support airway and breathing first.
- If arrest: start CPR and follow local ALS pathway while preparing drugs.
- If anaphylaxis: adrenaline IM immediately and call for senior help.
- If bradycardic and unstable: atropine then consider pacing.
- If arrhythmia with haemodynamic compromise: synchronised cardioversion per ACLS.

Study & exam strategy
For viva and short-answer exams practise saying the drug name, one indication and the key adult dose in one sentence. Example: "Adrenaline for cardiac arrest 1 mg IV every 3-5 minutes, for anaphylaxis 0.5 mg IM, call for senior help". Spend 10 minutes daily on flashcard drills using the pharmacology mnemonics PDF to speed recall.
