Medication reconstitution

Some fertility medicines, particularly certain gonadotropins and trigger injections, are supplied as a powder that must be mixed (reconstituted) with a provided liquid diluent before it can be drawn up and injected. This process needs to be done carefully and cleanly to avoid contamination and to ensure the medicine is mixed correctly. The clinic or pharmacist provides specific, hands-on demonstration of the reconstitution steps for each particular medicine and brand, since technique can vary between products; the manufacturer's package leaflet should also be followed. Any medicine that does not dissolve fully, looks discoloured, or where the process is unclear, should be discussed with the pharmacist or clinic before use rather than guessed at. Once reconstituted, some medicines must be used promptly and cannot be stored for later use; storage instructions on the label should always be followed.
