Interferon alpha is a protein normally produced by the body during viral infections, such as flu. It is given in the chronic phase of CML. Interferon alpha is given as a small injection under the skin using a very fine needle. The injections are slightly uncomfortable. You or a relative or friend can be taught how to give yourself these injections so that they can be done at home.
Side effects
Interferon alpha can cause side effects similar to the symptoms of flu, especially:
- chills
- fever
- headaches
- aching in the back, joints and muscles
- tiredness.
The side effects can be reduced by taking a mild painkiller before the injection. Your doctor can prescribe painkillers for you. The side effects are most noticeable with the first one or two injections and usually wear off after that, although the tiredness often continues. Interferon may cause depression in some people.
It may sometimes be given together with chemotherapy treatment.
