Contraindication

A contraindication is a reason why a particular treatment or procedure should not be used, or should only be considered under specific clinical circumstances. It may relate to another condition, an allergy, pregnancy or a medicine interaction. It is different from a side effect, although both influence treatment decisions.

Is it the same as a precaution?

Not exactly. A contraindication may rule out an option, while a precaution may mean extra assessment, monitoring or adjustment is needed. The distinction depends on the particular treatment and clinical situation. Do not decide from a single word in a leaflet without asking a qualified professional to explain it.

Consumer Medicine Information describes who should not use a medicine and important warnings. Read the information supplied with your own product and ask about anything that appears relevant. A generic internet checklist may not reflect your complete history.

For the Australian guidance behind this explanation, see Healthdirect Australia: How to read Consumer Medicine Information (CMI).

What should I tell the doctor?

Provide allergies, previous serious reactions, medical conditions, pregnancy or breastfeeding status and all current medicines and supplements. Mention planned surgery or recent changes in health. Information that seems unrelated can affect whether an option is safe.

Be specific about a past reaction: what happened, when it happened and whether it was medically assessed. An upset stomach and a severe allergic reaction are not interchangeable descriptions. Accurate information helps avoid both unsafe exposure and unnecessary exclusion of suitable options.

What if a warning seems to apply to me?

Contact the prescriber or pharmacist before starting or changing treatment. Do not ignore the warning, but do not abruptly stop an important medicine without appropriate advice unless emergency instructions apply. Severe allergic symptoms, collapse or serious breathing difficulty requires 000.

Doccio's prescription review service involves a doctor's assessment of suitability. A requested treatment may be declined or require further information when a contraindication or significant uncertainty is present. The decision should be explained in terms of your care.

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.
