Corticosteroids (glucocorticoids) for cancer and cancer pain

How It Works

Corticosteroids are strong anti-inflammatory drugs. They are used to reduce swelling that causes cancer pain.

Corticosteroids are available as pills, syrups, injections, and intravenous (IV) solutions. The type and extent of a disease determines the exact dose and schedule of administering these drugs.

Why It Is Used

Corticosteroids reduce swelling (inflammation) that causes cancer pain. They are used with other drugs, such as ondansetron and aprepitant, to control and prevent nausea and vomiting caused by chemotherapy.

How Well It Works

Corticosteroids work well to reduce swelling and pain caused by cancer. ¹ When they are used with other drugs, such as ondansetron and aprepitant, they may control and prevent nausea and vomiting caused by chemotherapy. ²

Side Effects

Side effects are common with steroids and can include:

• Nausea, vomiting, stomach upset, or ulcers. To reduce these side effects, take your pills with a full glass of fluid and a small snack.
• Fluid retention, causing swelling of the hands and feet.
• Increased appetite.
• Increased risk of infection.
• Preexisting diabetes getting worse.
• Menstrual period changes.
• Changes in behavior, such as symptoms of paranoia or psychosis.

Some problems may occur with long-term use. These include:

• Osteoporosis.
• Cataract formation.
• High blood pressure.

What To Think About

During treatment with corticosteroids, do not take any other prescription or nonprescription medicines, including herbal products, without first talking to your doctor. Many other drugs can interact with corticosteroids, resulting in side effects or changes in how well the drugs work.

Do not stop taking corticosteroids suddenly. Withdrawal effects can occur, so it is very important to take the prescribed dose at the times recommended by your doctor. You will be given instructions on how to reduce (taper) your dose gradually at the end of your treatment. Have your doctor write these instructions out for you. If you have any questions about how to taper your dose, call your doctor. Tapering is usually only necessary if you use corticosteroids for a long time. It may not be necessary if you use the steroids only for short periods.

Dexamethasone, if given too rapidly by IV, may cause temporary itching or burning in the vaginal or rectal area. This goes away after a few minutes.

To minimize side effects of oral corticosteroids, take your pills with a full glass of liquid and a small snack.

Corticosteroids should be used during pregnancy only if the benefits to the mother outweigh the risks to the fetus. If you are or may be pregnant, talk to your doctor before using corticosteroids. This drug can pass through your body into breast milk and should not be used while you are breast-feeding.

Avoid sources of infection. Wash your hands frequently, and keep them away from your mouth and eyes. Your immune system may be weakened while you are taking corticosteroids.

Steroids used to treat cancer and cancer pain are not the same as steroids used by body builders (anabolic steroids).

Do not use alcohol or street drugs while you are taking corticosteroids. Tell your doctor if you need more pain relief.
