What Synacthen is used for
Synacthen is used as a diagnostic test to find out if the adrenal glands, small glands next to the kidneys, are working as well as they should. The Synacthen test is given as a single injection into the muscle.
Synacthen is used as a test only. It is not used to treat poorly functioning adrenal glands.
Ask your doctor if you have any questions about why Synacthen has been prescribed for you.
Your doctor may have prescribed it for another reason.
Synacthen is only available with a doctor’s prescription. It is not habit- forming.

Before you start to have it
Tell your doctor if you have asthma or allergies, including any allergies to other medicines, foods, dyes or preservatives.
If you have asthma or allergies, your chance of having an allergic reaction to Synacthen may be greater than normal. Your doctor can discuss this with you further.

Your doctor may want to take special precautions if you have one of the above conditions.
Taking other medicines
Tell your doctor or pharmacist if you are taking or have recently
taken any other medicines, including medicines obtained without a prescription from a pharmacy, supermarket or health food shop.
These include medicines used to treat:
diabetes
high blood pressure
convulsions
It may be necessary to change the dose or in some cases to stop the medicine.
Some medicines may affect the results of the Synacthen test. These include:
some corticosteroid medicines, including cortisone and hydrocortisone
spironolactone, a medicine usually used to treat high blood pressure and fluid retention
oestrogens, including the birth control pill and hormone replacement therapy (HRT)
Your doctor may ask you to skip the morning dose of some medicines on the day of the Synacthen test so that the test results are not affected.
If you have not told your doctor about any of these things, tell him/her before you have the Synacthen test.
How Synacthen is given
You will be given a single injection of Synacthen into the muscle. You will have two blood samples taken, one before the dose of Synacthen and the other 30 minutes after the dose. These blood samples will show whether your adrenal glands are functioning as well as they should.
Afterhaving Synacthen
Things to be careful of
Be careful driving, operating machinery or doing jobs that require you to be alert after you have had the Synacthen test until you know how it has affected you.
Although Synacthen is unlikely to have affected your reactions, make sure before you drive or do anything else that could be dangerous.
Side effects
Tell your doctor or nurse as soon as possible if you do not feel well while you are having the Synacthen test, even if you don’t think it is connected with the medicine.
All medicines can have side effects. Sometimes they are serious, but most of the time they are not. You may need medical treatment if you get some of the side effects.

redness or pain at the injection site
rash, itching, hives or flushing of the skin
