Disease modifying drugs
Disease modifying drugs are not a cure for MS, but they can reduce the frequency of relapses.
Scientists don't yet know whether any of these drugs will slow down the rate of disability in the long term. Unfortunately they're not effective for primary progressive MS.
Clinical trials have shown that disease modifying drugs (DMDs) reduce the number of MS relapses by around a third over two years.
Like all drugs, DMDs cause some side effects, and have criteria for who can access them. The most common drugs are injected.
Unlicensed drugs may also be used to treat MS, perhaps because licensed drugs haven't worked well for an individual.
