What Synacthen Depot is used for

Synacthen Depot has two very different uses:
It is used in people with multiple sclerosis who are experiencing a worsening of their symptoms
It is used in young children to treat some types of seizure (fit), such as infantile spasms.
Synacthen Depot works by causing the adrenal glands to increase the production of natural "steroid" hormones that can help to reduce the symptoms of certain diseases.
This medicine is not suitable for newborn babies, especially if they are premature, because it contains benzyl alcohol, which can cause severe side effects in very young babies. It must also be used with caution in children up to 3 years of age.
Ask your doctor if you have any questions about why Synacthen Depot has been prescribed.
Your doctor may have prescribed it for another reason.

How long treatment lasts
