How should I take dexamethasone?
Take this medication exactly as it was prescribed for you. Do not take the medication in
larger amounts, or take it for longer than recommended by your doctor. Follow the directions on
your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results from
this medication.
Your steroid medication needs may change if you have unusual stress such as a serious
illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about
any such situation that affects you.
This medication can cause you to have unusual results with certain medical tests. Tell any
doctor who treats you that you are using dexamethasone.
Do not stop using dexamethasone suddenly, or you could have unpleasant withdrawal
symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the
medication.
Carry an ID card or wear a medical alert bracelet stating that you are taking a steroid,
in case of emergency. Any doctor, dentist, or emergency medical care provider who treats you
should know that you are taking steroid medication.
Store dexamethasone at room temperature away from moisture and heat.
What happens if I miss a dose?
If you miss a dose or forget to take your medicine, contact your doctor or pharmacist for
instructions.
What happens if I overdose?
Seek emergency medical attention if you think you have received too much of this
medicine.
A single large dose of dexamethasone is not expected to produce life-threatening
symptoms. However, long-term use of high steroid doses can lead to symptoms such as thinning
skin, easy bruising, changes in the shape or location of body fat (especially in your face, neck,
back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest
in sex.
What should I avoid while taking dexamethasone?
Avoid being near people who are sick or have infections. Call your doctor for preventive
treatment if you are exposed to chicken pox or measles. These conditions can be serious or even
fatal in people who are using steroid medication.
Do not receive a "live" vaccine while you are being treated with dexamethasone.
Vaccines may not work as well while you are taking a steroid.
Avoid
drinking alcohol while you are taking dexamethasone.
