Safe prescribing habits for new doctors

For many new doctors, the first prescription feels like a big moment. It should. Medication errors are among the most common causes of avoidable harm in hospital, and most of them come from busy people skipping a step, not from a lack of knowledge.

This post isn't about which drug or dose to choose. It's about the habits that make any prescription safer.

Before you prescribe

Know the patient. Confirm their identity, age and weight where it matters. Check kidney and liver function, because both affect how many medicines are handled.

Check allergies properly. Ask the patient directly, check the notes, and clarify what the reaction actually was. A rash, a true allergy and a side effect like nausea are different things, and the distinction matters.

Take a full medication history. Include over-the-counter medicines, herbal remedies and anything recently stopped. Many errors happen at transitions, such as admission and discharge, when a regular medicine is missed or duplicated.

Consider pregnancy and breastfeeding where relevant.

When you prescribe

• Know why. Be able to state the indication clearly. If you can't, pause and ask.
• Check interactions. Use your local formulary or reference resource every time, not your memory.
• Use the approved reference, not a guess. Look up the dose, route and frequency in a trusted source, even for medicines you think you know.
• Write clearly and completely. Use approved names, avoid unofficial abbreviations, and make sure the route, frequency and duration are all there.
• Be especially careful with high-risk medicines. Anticoagulants, insulin, opioids and medicines with a narrow therapeutic range deserve extra checks.

After you prescribe

Plan the review. Every prescription should have an endpoint or a review date. Antibiotics in particular need a planned review.

Decide what to monitor. Some medicines need blood tests or observations to check they're working and not causing harm. Make sure someone knows to do them.

Talk to the patient. Explain what the medicine is for, the common side effects, and what should make them seek help. This is part of safety-netting.

Ask for help early

The safest prescribers aren't the ones who know everything. They're the ones who know when to check. Pharmacists are an excellent resource, and asking a senior or a pharmacist is a sign of good practice, not weakness.

A useful rule of thumb: if you feel uncertain, that feeling is information. Stop and check.

Build the habits before you need them

Habits formed as a student carry into your first job. When you work through a Sushruta case, treat the treatment and follow-up stages as if they were real: state your reasoning, think about allergies and interactions, and plan monitoring and review. The treatment axis of your grade looks at whether management is appropriate, safe and proportionate, and the follow-up axis checks your monitoring and safety-netting.
