What happens if I miss a dose?

Since dexamethasone injection is given as needed by a healthcare professional, it is not likely that you will miss a dose.

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 after receiving dexamethasone?

Avoid activities that place too much stress on your joints. Dexamethasone can decrease pain and swelling, and you may be tempted to increase your activity if you are feeling better. Any joint damage may go unnoticed while you are being treated with 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 using a steroid. Ask your doctor when you can safely receive a live vaccine after your dexamethasone treatment ends.

What other drugs will affect dexamethasone?

There are many other medicines that can interact with steroids. Below is only a partial list of these medicines:

• aspirin (taken on a daily basis or at high doses);
• a diuretic (water pill);
• a blood thinner such as warfarin (Coumadin);
• diet pills, or cough and cold medications;
• indomethacin (Indocin); or
• seizure medications such as phenytoin (Dilantin) or phenobarbital (Luminal, Solfoton).

This list is not complete and there may be other drugs that can interact with dexamethasone. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.

Where can I get more information?

Your pharmacist can provide more information about dexamethasone.

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
