Antimalarial medications are used to treat malaria and are also
prescribed for
lupus (systemic lupus erythematosus, or SLE) and
rheumatoid arthritis.
How It Works
These medications reduce
inflammation. (While they are also used to prevent or
treat malaria, there is no known relationship between lupus and
malaria.)
Why It Is Used
These medications are used to control skin rash in people who have
lupus. They also may help relieve muscle and joint pain, fatigue, and fever
that are not controlled with nonsteroidal anti-inflammatory drugs (NSAIDs).
These medications may be used together with anti-inflammatory drugs
or
corticosteroids. Using them may allow you to reduce
the dose of steroids to a level that causes fewer or less bothersome side
effects.
How Well It Works
Antimalarial medication is used with corticosteroid
creams to control lupus skin rash, and it has long been used to
control lupus-related muscle and joint pain.1 For skin
rash, this treatment works best when it is combined with protecting the skin
from the sun.
Hydroxychloroquine may protect against lupus disease
flares.1
Side Effects
The most significant side effect of antimalarials is damage to the
tissue that lines the eye (retina). This is rare when hydroxychloroquine is
given at appropriate doses. Monitoring of vision is essential to prevent eye
damage.2
Other side effects include occasional rash, nausea, or diarrhea.
These medications are generally well tolerated.
See Drug Reference for a full list of side effects. (Drug Reference
is not available in all systems.)
What To Think About
It may take several months for these medications to work. If
antimalarial treatment doesn't seem to be helping within 6 months, your doctor
will probably recommend that you stop taking it.
An initial eye examination will be done if you are taking
hydroxychloroquine (Plaquenil) or chloroquine (Aralen).2 After the initial eye examination, your doctor may
require eye exams every year or may ask you to check your
eyesight regularly with an eye test at home (as with an
Amsler
grid
). If there is a
change in your eyesight, your doctor may reduce your dose or recommend that you
stop taking the medication to prevent permanent eye damage. If antimalarial
medication is effective, the dose may be tapered or taken less often to reduce
the risk of permanent eye damage.
The dose of antimalarial medication may be adjusted if you have
kidney or liver disease.
One study reports that hydroxychloroquine is
probably safe to use during pregnancy. Talk to your doctor about this
medication if you are pregnant or are considering pregnancy and have
lupus.3
