Dose instructions

Dose instructions explain how much medicine to take, how to take it, when to take it and sometimes how long to continue. They are specific to the product and patient. A familiar name or previous prescription does not mean the same directions apply to a new supply or a changed treatment plan.

Which instructions should I check?

Read the dispensing label and any information provided by the prescriber or pharmacist. Confirm the amount per dose, timing, route and duration. Instructions such as use when needed still require a clear explanation of the circumstances and any maximum amount.

If a label and verbal advice appear inconsistent, ask the pharmacist or prescriber to reconcile them before guessing. Do not use another person's directions, and do not assume that one tablet always represents the same dose across different strengths.

What if I miss a dose?

The right response depends on the medicine and timing. Check the product information or ask a pharmacist. Do not automatically double the next dose. If you repeatedly miss doses, discuss a practical plan rather than hiding the difficulty or changing the schedule yourself.

Tell the clinician about swallowing problems, shift work, cost or a routine that makes the instructions difficult to follow. They may be able to clarify the plan or consider another appropriate approach. A written schedule can help when several medicines are involved.

How should I prepare for a review?

Bring a current list showing what you actually take, not only what was originally prescribed. Include non-prescription products and supplements. Ask which old supplies should no longer be used and how to dispose of them safely.

See Doccio's prescription service for suitable clinical reviews. A doctor decides whether continuation or changes are appropriate. For a suspected overdose or poisoning, seek immediate advice through the Poisons Information Centre on 13 11 26, or call 000 for severe symptoms.

Where to go next

Read prescription consultations to understand the relevant service. A doctor decides whether a consultation, examination, referral or another pathway is appropriate for your situation.
