Prednisone (Deltasone) is part of a potent class of anti-inflammatory agents, known as corticosteroids, which are used to control inflammation of the joints and organs. It is often used to treat a variety of inflammatory conditions, including redness, swelling, and pain. Prednisone is used to treat rheumatoid arthritis, lupus, vasculitis, and many other inflammatory diseases.

How to Take It

Dosing of prednisone varies widely depending on the state of the disease being treated.  Doses used in rheumatoid arthritis are commonly 5-10mg daily, while doses needed in lupus and vasculitis are often 60–80 mg daily, or sometimes higher. The dose is usually decided based on your weight and disease manifestations. Prednisone usually achieves its effect within one – two hours. The delayed release tablets take effect about six hours after taking the dose. Prednisone stops working soon after stopping the medication.  If you have been taking prednisone regularly for longer than two weeks, do not stop it suddenly because you could develop adrenal insufficiency. Instead, you should discuss a tapering schedule with your rheumatology provider.

Side Effects

Most side effects are related to the dose administered and duration of treatment, so the goal is to use it at the lowest effective dose for the shortest period of time necessary. Some potential side effects include easy bruising, osteoporosis (or weakened bones), diabetes, hypertension, weight gain, cataracts, glaucoma, and a bone disorder called avascular necrosis.

Although prednisone rarely has a direct interaction with other medications, there is an increased risk of infection when combining prednisone with other medications that affect your immune system. At higher doses of prednisone, your provider may also prescribe you prophylactic medications to prevent pneumonia. Additionally, when taking prednisone with NSAIDs (such as naproxen or ibuprofen), there can be an increased risk of stomach ulcers. Make sure to review all of your medications with your physician at each visit.

Tell Your Rheumatology Provider

Your doctor will monitor you for side effects.  Be sure to discuss any new symptoms you are experiencing with your rheumatology provider.

Talk to your rheumatology provider about which vaccines are appropriate for you, as it depends on your dose of prednisone.

If you are pregnant or are considering pregnancy, discuss this with your doctor before starting medication. Although prednisone can be necessary to use during pregnancy, complications can still birth, and premature delivery.  Babies born from women receiving large doses of corticosteroids during pregnancy can develop under active adrenal glands and also can be smaller than expected at birth. Babies can develop cleft lip and cleft palate as well. Although some of the drug passes into breast milk, prednisone appears to be safe while breastfeeding. After a dose >20 mg of prednisone, a 4-hour delay in breastfeeding is recommended.

Methotrexate for Your RA

Methotrexate is one of the most effective medications to treat rheumatoid arthritis (RA). It's the first drug most doctors prescribe after you’re diagnosed.

It will help ease symptoms like joint pain, fatigue, redness, and swelling. It may also help prevent damage to your organs and joints.

How Does It Work?

Methotrexate interrupts the process that causes RA inflammation, which damages your joints and organs over time.

Your doctor may call it a “DMARD,” which is a type of RA drug. (DMARD stands for disease-modifying antirheumatic drug).

How Do You Take It?

You can take methotrexate in either pills or shots. There are prefilled methotrexate shots that are easy to take at home.

You will take 7.5 to 10 milligrams each week. Your doctor may raise that to 20-25 milligrams per week if needed.

The pills will come with directions about how many to take and when. If you’re not sure about those instructions, ask your doctor or a pharmacist.

Shots work better for some people, especially if you forget to take your pills on schedule or if the pills cause nausea. Methotrexate liquid comes in vials with a hypodermic needle or in prefilled pens with various doses.

You inject the drug under the skin on your stomach or thigh. Your doctor or nurse will show you how to do this at home. If you use a prefilled pen, you’ll stick the pen into your stomach or thigh and press on it to inject the drug. Try to give yourself your shot in a different spot each time. This will help you avoid skin reactions.

It can take 3 to 6 weeks to start to feel your methotrexate work. It takes even longer -- 12 weeks -- to get the full effects.

Your doctor will test your blood often to check on how well your treatment works and to make sure it’s safe for organs such as your liver.

Other Drugs You May Take

Your doctor may prescribe methotrexate alone. Or you may also take other drugs like aspirin, nonsteroidal anti-inflammatory drugs, low-dose steroids, or other DMARDs.

You’ll probably take folic acid supplements along with methotrexate. This vitamin can help you lower your chance of certain side effects.

Talk to your doctor before you take any drug or supplement. Not all drugs mix well. Taking biologics is not recommended while taking methotrexate. 

What Are the Side Effects?

You may notice these side effects while you take methotrexate:

  • Dizziness
  • Drowsiness
  • Headaches
  • Swollen or tender gums
  • Hair loss
  • Decreased appetite
  • Mouth sores
  • Rash
  • Diarrhea

Tell your doctor if you have them. They can adjust your dose so you feel better. Minor side effects should lessen over time.

Methotrexate and Your Liver

This drug can harm your liver. You’ll visit the doctor regularly to check on how methotrexate affects your body. Your doctor might test your liver as often as once a month for the first 6 months you take the drug. After that, you may get a liver test every 3 months.

Methotrexate and Infections

You’re more likely to get an infection while you take methotrexate. So take these steps to stay well:

  1. Try to avoid people with infections like colds or flu.
  2. Wash your hands regularly.
  3. Tell your doctor if you have fever, chills, or a cough.

Other Concerns

Methotrexate can also:

  • Make lymphoma (cancer of the lymphatic system) more likely.
  • Make your skin more sensitive to the sun. Use sunscreen, wear protective clothing, and don’t use sunlamps or tanning beds.
  • Cause birth defects. If you or your partner could get pregnant, you should use birth control while on methotrexate. Men should continue to use protection for 3 months after the last dose. Women should stay on birth control for at least 1 menstrual cycle after the last dose and not breastfeed while taking methotrexate.
  • Cause lung problems, although this is rare. Tell your doctor if you cough frequently or have shortness of breath.
