In case of overdose

If you are given too much (overdose)

As Phenylephrine BNM is given to you in hospital under the supervision of your doctor, it is very unlikely that you will receive too much.

If you are not in a hospital, immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26 in Australia), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have been given too much Phenylephrine BNM.

Like all medicines, Phenylephrine BNM may occasionally cause side effects in some people. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Ask your doctor or nurse to answer any questions you may have.

Tell your doctor or nurse if you notice any of the following and they worry you:

After receiving Phenylephrine BNM


Phenylephrine BNM should only be given to you in hospital. It will be stored in a cool dry place away from the light, where the temperature stays below 25°C.

The ampoules should not be taken out of the box until just before they are to be used. This is because the medicine is affected by light.


Any Phenylephrine BNM which has passed its expiry date, or is left in the container after use, will be disposed of in a safe manner by your doctor, nurse or pharmacist.
