What Sevorane is used for?
Sevorane belongs to a group of medicines called halogenated anaesthetic agents, which are breathed in to induce and/or maintain anaesthesia.
This medicine is administered by an anaesthetist in the air you breathe when you go for surgery. It is a colourless liquid supplied in a bottle. It is given by your anaesthetist using a vaporiser, which turns the liquid into a gas so that you can breathe it in.
Sevorane is used for inducing and maintaining heavy sleep needed during surgery. The medicine produces loss of consciousness and pain sensations during surgery.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.

When you must not receive it.
Sevorane should not be given to patients who are not suitable for receiving a general anaesthetic.
Sevorane should not be given to patients who are allergic or sensitive to halogenated anaesthetic agents.
Before Sevorane is started
Sevorane may cause drowsiness, tiredness or weakness for a while after it has been administered. It may also cause problems with coordination and ability to think. Therefore, for at least 24 hours (or longer if necessary) after receiving Sevorane, do not drive, operate moving machinery, or do anything else that could be dangerous if you are not alert.
Ask your doctor when you can drive and/or return to work involving machinery or heavy equipment.
Unless otherwise directed by your doctor, do not drink alcoholic beverages or take other central nervous system (CNS) depressants (medicines that may make you drowsy or less alert) for about 24 hours after you have received Sevorane. Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies or colds; other sedatives, tranquillisers or sleeping medicine, prescription pain medicine or narcotics; barbiturates; medicines for seizures; and muscle relaxants.
How Sevorane is given
Only persons trained in the administration of general anaesthesia give Sevorane. It is given using a vaporiser. The dose of Sevorane will be adjusted to keep you at the right depth of sleep.
If you are given too much Sevorane
As Sevorane is given under strict supervision is it unlikely that you will receive too much. However, the anaesthetist can reduce the dose of Sevorane and provide oxygen should your blood pressure be too low or you have difficulty in breathing.
As with all medicines, unwanted effects sometimes happen. Rarely Sevorane may produce unwanted effect, which you may wish to know about.
Do not be alarmed by the following lists of side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Sevorane may cause some lowering of blood pressure and breathing rate, changes in heart rate or seizures. You will not know about these things since you will be asleep but your anaesthetist will adjust the dose of Sevorane as necessary and will give you other medicines if needed.
Sevorane may cause coughing, dizziness, drowsiness and increased salivation.
Sevorane may cause disturbances of liver function in some people. After your operation, tell your doctor if you develop the following symptoms of liver problems: nausea, vomiting, loss of appetite, feeling generally unwell, fever, itching, yellowing of the skin and eyes, light coloured bowel motions and/or dark coloured urine.
Some people may experience shivering, nausea and vomiting upon waking from the general anaesthesia.
It is possible that Sevorane may cause a rare group of symptoms known as malignant hyperthermia. The features of this are muscle rigidity, fast pulse, breathing heavily and quickly, bluish lips and skin, changes in blood pressure and a fever. Your doctor will treat this by stopping the Sevorane and using other medications as needed.
After anaesthesia there may be a brief rise in your white blood cell count. Your doctor will monitor this if it happens.
