REMIFENTANIL ALPHAPHARM is an anaesthetic used with other anaesthetic medicines, to produce and/or maintain heavy sleep during your operation. If you are a cardiac patient, it may also be used to help relieve any pain immediately following your operation.
REMIFENTANIL ALPHAPHARM may also be used for patients in the Intensive Care Unit to maintain sedation and relieve pain.
REMIFENTANIL ALPHAPHARM belongs to a group of medicines called opioids. It differs from other medicines in this group by its very quick onset and very short duration of action.
Your doctor may have prescribed REMIFENTANIL ALPHAPHARM for another reason.
Ask your doctor if you have any questions about why REMIFENTANIL ALPHAPHARM has been prescribed for you.
You can become addicted to REMIFENTANIL ALPHAPHARM even if you receive it exactly as prescribed. REMIFENTANIL ALPHAPHARM may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.
As with all other opioid containing products, your body may become used to you using REMIFENTANIL ALPHAPHARM. Using it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop receiving REMIFENTANIL ALPHAPHARM suddenly.
Tolerance to REMIFENTANIL ALPHAPHARM may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.
If you stop receiving this medicine suddenly, your pain may worsen and you may experience some or all of the following withdrawal symptoms:
nervousness, restlessness, agitation, trouble sleeping or anxiety
body aches, weakness or stomach cramps
loss of appetite, nausea, vomiting or diarrhoea
increased heart rate, breathing rate or pupil size
watery eyes, runny nose, chills or yawning
increased sweating.
REMIFENTANIL ALPHAPHARM given to the mother during labour can cause breathing problems and signs of withdrawal in the newborn.

You must tell your doctor if:
you have had any adverse reactions during an operation

slow heart beat
low blood pressure
