Medicine safety starts with the exact pack in hand.
For older adults, families and carers, the safest useful first step is to identify the exact product, read its current label and bring a complete medicine list to a pharmacist or prescriber. This page does not calculate doses or make treatment choices.

Twenty-three everyday medicine questions, in plain language
These short answers help a family prepare the right next question. They do not calculate a personal dose, decide a combination, or replace the current label for the exact product in hand.
The box says mg. Does that tell me how many tablets to take?
No. mg describes the labelled amount in one tablet, capsule, measured liquid volume or another unit. Keep the medicine name, form, number and unit together, then read the prescription label and current leaflet for that exact pack.
Open the medicine listCan different strengths or a liquid be swapped?
Not from the numbers alone. A 250 mg capsule, a 500 mg capsule and 250 mg/5 mL liquid describe different labelled product identities. Keep the exact form, strength or concentration, market and pack with the prescriber or pharmacist for review.
Read the AMOXIL / amoxicillin recordCan one tablet be broken in half?
Do not treat this as arithmetic. A score line, another brand, or an older pack is not enough. Find an explicit instruction in the current label for this exact product and ask a pharmacist before splitting, crushing, chewing or opening it.
Find the exact recordCan two medicines with a similar purpose be taken together or on alternate days?
Do not create a same-day, alternate-day, switch or stop plan from similar names or milligram numbers. List every prescription, OTC product and supplement so a pharmacist or prescriber can review the complete picture.
Make a private medicine listCan atorvastatin and rosuvastatin be alternated?
They are both statins, but that does not make them self-interchangeable. The exact products, prior effects, other medicines, conditions and current labels all need professional review before any change.
Read the statin comparisonWhy might two people be given different statins?
A medicine choice is not a ranking of people or brands. The treatment goal, exact product, other medicines, medical history, current label and the person's overall clinical review can all matter. Ask the prescriber or pharmacist to explain the reason for the specific plan; do not copy or exchange a family member's statin.
Read the statin comparisonDoes everyone need broad genetic testing before a medicine change?
No. Existing pharmacogenomic results can be relevant in some defined situations, but a medicine name alone cannot decide whether testing is needed or what a result means. Ask a specific question about one medicine and one proposed decision.
Read the label-reading guideThe pack looks different. Is it still the same medicine?
Different colour, shape, pack or market wording is a reason to check, not proof of a match or a problem. Compare the name, active ingredient, form, strength, market and official record before use; a photo alone does not confirm authenticity.
Read pack text on this deviceCan modified-release or enteric-coated tablets be split or crushed?
Do not decide from letters such as SR, CR, ER, XR, LA or MR, or from appearance alone. Some products need special handling and the exact label may differ by product and market. Keep the tablet whole unless the current leaflet for that exact pack says otherwise and a pharmacist confirms it.
Find the exact recordI missed several days. Can I simply restart the old amount?
Not until the exact medicine is checked. Some medicines have product-specific restart, titration or monitoring instructions. Keep the pack, the last time taken, the old directions and every other medicine together for a pharmacist or prescriber to review.
Make a private medicine listSomeone took an extra dose or the wrong medicine. What information matters now?
For an accidental extra dose or wrong product, do not make up a correction on the website. Keep the pack and write down the exact name, strength, form, amount, time, age and body weight if known. For a child, a large amount, a dangerous symptom or uncertainty, contact local poison or emergency services now.
View the emergency boundaryHow should I record a possible side effect?
Record the exact product, amount, time taken, when the concern began, what changed, every other medicine or supplement, and any photos of the pack—not a diagnosis. A pharmacist or prescriber can then assess the complete timeline; urgent warning signs need urgent care.
Make a private medicine listCan ageing or kidney and liver changes alter an old medicine plan?
They can matter, but a website cannot calculate a new personal plan. Bring the exact packs, current directions, recent changes and complete medicine list to the clinician or pharmacist who is reviewing kidney, liver and overall health information.
Read the label-reading guideCan two fever medicines be alternated for a child?
Do not build an alternating timetable from memory, brand names or a web example. Child products vary by active ingredient, concentration and measuring device. Use the child-specific directions supplied by a clinician or pharmacist, and write down every product, amount and time to prevent duplicate dosing.
Read the label-reading guideOn an injection pen, is the dial a unit, a milligram or a millilitre?
Do not infer it from the number alone. The dial, pen model, medicine, concentration and current instructions must all match. Ask the dispensing pharmacist or prescriber to show the exact device before using it, especially after a product or pen change.
Make a private medicine listThe prescription label and the leaflet look different. Which one should I follow?
Do not choose between them from a web summary. Keep the exact pack and prescription label together, and ask the dispensing pharmacist or prescriber to resolve any difference before the next dose. A different market, product version or route can change what a label says.
Read the label-reading guideCan I take this medicine with food, milk, juice or only water?
There is no universal rule. Food, drinks and the way a product is taken can matter for some medicines. Check the current leaflet for the exact product and ask a pharmacist rather than copying a rule from another medicine or a previous pack.
Find the exact recordCan I add an over-the-counter cold, pain or sleep product?
Not until the active ingredients and complete medicine list have been checked. Non-prescription products and supplements can duplicate an ingredient or interact with prescription medicines. Bring the exact boxes or photos of all labels to a pharmacist before combining them.
Make a private medicine listCan I add ibuprofen or naproxen when I use an anticoagulant or antiplatelet medicine?
Do not add a pain medicine simply because it is common or sold without a prescription. Keep every medicine pack and supplement together for a pharmacist to review. For black stools, vomiting blood, bleeding that will not stop, or feeling unwell after a fall or head injury, use local urgent or emergency care rather than waiting for a website answer.
Read the anticoagulant and pain-medicine questionCan I use an old or expired leftover medicine?
Do not make that decision from the medicine name or how the pack looks. The exact product, expiry date, storage history, intended user and current treatment plan all matter. Ask a pharmacist how to handle it and use local safe-disposal guidance rather than saving it for a future illness.
Read the label-reading guideCan a family member use my medicine if the name seems the same?
No. A matching name does not establish the same person, condition, form, strength, allergies, other medicines or instructions. Do not share prescription medicines; have the other person assessed and use their own current directions and product record.
View the emergency boundaryA weekly methotrexate medicine was taken every day. Is this urgent?
Yes. A daily-versus-weekly mix-up can be a serious medication error. Do not use a website to calculate a correction. Keep the pack and record the exact name, strength, form, amount and times taken; contact local poison or emergency services now.
View the emergency boundaryWhen should we stop searching and seek urgent help?
For a suspected overdose, severe allergic reaction, fainting, difficulty breathing, uncontrolled bleeding or a major new concern, use local emergency or poison-information services now. Bring the pack and medicine list; do not wait for a website answer.
