Frequently asked questions

Why is deflazacort used in Duchenne muscular dystrophy?

Steroids help preserve muscle strength and walking ability for longer; deflazacort is one of the main options.

Does it cause less weight gain than prednisolone?

Some studies suggest less weight gain, but other side effects such as cataracts may be more common. Your doctor chooses based on the child.

Can my child have vaccines?

Inactivated vaccines are fine, but live vaccines are avoided; ideally vaccines are updated before starting.
