Usage
To treat numerous conditions
that involve inflammation (a
response by body tissues,
producing redness, warmth,
swelling, and pain). Such
conditions include arthritis,
allergic reactions,
asthma,
some skin diseases, multiple
sclerosis flare-ups, and other
autoimmune diseases. Also
prescribed to treat deficiency
of natural steroid hormones.
How it works
Prednisone mimics the
body's natural corticosteroid
hormones. It depresses the
synthesis, release, and activity of inflammation-producing
body chemicals. It also
suppresses the activity of
the immune system.
Side effects
- Serious
- Vision problems, frequent urination, increased thirst,
rectal bleeding, blistering skin, confusion, hallucinations,
paranoia, euphoria, depression,
mood swings, redness
and swelling at injection site.
- Common
- Increased appetite, indigestion, nervousness,
insomnia,
greater susceptibility to infections, increased
blood
pressure, slowed wound healing, weight gain, easy
bruising,
fluid retention.
- Less common
- Change in skin color, dizziness,
headache, increased
sweating, unusual growth of body or facial hair, increased
blood sugar, peptic ulcers, adrenal insufficiency,
muscle
weakness, cataracts,
glaucoma,
osteoporosis.
Possible interactions
- Other medicaments:
Prednisone may decrease the effects of:
- insulin (various), requiring dosing changes of insulin.
- isoniazid (INH, Niconyl, etc.).
- salicylates (aspirin, sodium salicylate, etc.).
- vaccines (such as flu vaccine), by blunting the immune response to them.
Prednisone taken concurrently with:
- amphotericin B (Abelcet, Fungizone) may result in additive potassium
loss.
- birth control pills (oral contraceptives) will prolong the prednisone effect.
- clarithromycin (Biaxin) may lead to psychotic symptoms. Patient behavior
must be closely watched if these medicines are combined.
- cyclosporine (Sandimmune) can cause increased cyclosporine levels and
increased prednisone levels. Dose decreases may be needed for both medicaments.
- foscarnet (Foscavir) may result in additive potassium loss.
- ketoconazole (Nizoral) will lessen the therapeutic benefits of ketoconazole.
- loop diuretics (furosemide [Lasix], bumetanide [Bumex]) may blunt their
effects.
- macrolide antibiotics (erythromycin, troleandomycin and perhaps others)
can lead to prednisone toxicity.
- NSAIDs may result in additive stomach and intestinal irritation.
- oral anticoagulants may either increase or decrease their effectiveness;
consult your physician regarding the need for prothrombin time testing and dose
adjustment.
- oral antidiabetic medicaments or insulin may result in loss of
glucose control.
- ritonavir (Norvir) and perhaps other protease inhibitors
may lead to toxicity.
- theophylline (Theo-Dur, others) may result in variable responses to this
medicine. Increased frequency of theophylline level testing is recommended.
- thiazide diuretics or loop diuretics may result in additive
potassium loss.
- vaccines (flu, pneumococcal, varicella and others) may result in blunted
response to the vaccine and decreased preventive benefits.
The following medicaments may decrease the effects of prednisone:
- antacids-may reduce its absorption.
- barbiturates (Amytal, Butisol, phenobarbital, etc.).
- carbamazepine (Tegretol).
- phenytoin (Dilantin, etc.) and fosphenytoin (Cerebyx).
- primidone (Mysoline).
- rifampin (Rifadin, Rimactane, etc.).
- Foods:
- Ask your doctor about restricting salt or
eating potassium-rich foods. During long-term use,
it is best to eat a high-protein diet.
- Herbal medicines or minerals:
- Hawthorn,
ginger,
garlic,
ma huang,
ginseng and
nettle may change blood
sugar.
Fir or
pine needle oil should not be used by asthmatics. Ephedra alone does
carry a German Commission E monograph indication for asthma
treatment. If you are allergic to plants in the Asteraceae family (aster,
chrysanthemum, daisy or ragweed), you may also be allergic to
Echinacea,
chamomile,
feverfew and
St. John's wort.
During long-term use, take a vitamin D supplement and increase
calcium. During
wound repair, take a zinc supplement.
Potassium loss may need to be replaced.
Talk to your doctor before adding any herbal to any other medicines that you
already take.
- Alcohol:
- Use caution if you are prone to peptic ulcers.
- Tobacco smoking:
- Nicotine increases the blood levels of naturally produced cortisone.
- Marijuana smoking:
- May cause additional impairment of immunity.
- Occurrence of unrelated illness:
- This medicament may decrease resistance to infection.
Tell your doctor if you develop an infection of any kind. It may also reduce
your ability to respond to the stress of acute illness, injury or surgery. Keep
your doctor informed of any changes in health.
- Discontinuation:
- After long-term use, do not stop prednisone abruptly. For 2
years after stopping this medicament, it is essential in the event of illness, injury or
surgery that you tell medical personnel that you have used this medicament.
