What Are the Side Effects of Prednisone for Sarcoidosis?

At a Glance

Prednisone effectively treats sarcoidosis but carries short-term risks like insomnia and weight gain, and long-term risks like osteoporosis and diabetes. Because stopping suddenly can cause a life-threatening adrenal crisis, patients must always safely taper their dose under a doctor's guidance.

Prednisone is a highly effective corticosteroid (a medication that mimics your body’s natural anti-inflammatory hormones) used as a first-line treatment for sarcoidosis [1][2]. While it is excellent at calming the immune system and protecting your organs from damage, it comes with a wide range of short- and long-term side effects [1][3]. Because of these risks, your doctor’s goal will always be to use the lowest effective dose for the shortest amount of time possible [2].

Short-Term Side Effects

When you first start taking prednisone, you may notice side effects within a few days or weeks. These often depend on your dose and typically improve as your dose is lowered:

  • Increased risk of infections: Prednisone suppresses your immune system, making you significantly more susceptible to bacterial, viral, and fungal infections [4][5]. Contact your doctor immediately if you develop a fever or unusual signs of illness.
  • Stomach irritation and ulcers: Prednisone can cause gastritis or peptic ulcers [6]. Always take it with food. The risk of serious stomach bleeding increases significantly if combined with NSAIDs (like ibuprofen or naproxen), so consult your doctor before taking these over-the-counter pain relievers [7].
  • Weight gain and increased appetite: Prednisone commonly causes a sharp increase in hunger, leading to weight gain [8]. Focusing on a high-protein, high-fiber diet and staying hydrated can help manage these cravings.
  • Mood changes and anxiety: It is very common to experience mood swings, feeling “wired” or anxious, and in some rare cases, more severe psychiatric symptoms like paranoia or psychosis [9][10].
  • Insomnia and sleep disturbances: Prednisone can disrupt your natural sleep cycle, making it difficult to fall or stay asleep [11]. Taking your dose with breakfast or before 9:00 AM can help minimize this disruption [12].
  • Physical and skin changes: You may experience fluid retention leading to a rounded face (often called “moon face”), as well as acne, thinning skin, and easy bruising [13].
  • Increased risk of blood clots: Corticosteroid therapy can increase the short-term risk of developing a venous thromboembolism (a blood clot in your veins) [14]. Seek emergency care immediately if you experience sudden leg swelling, chest pain, or shortness of breath.

Long-Term Risks

When prednisone is taken for several months or years, the cumulative dose increases the risk of more serious side effects [15]. Your care team will monitor you closely for these metabolic and systemic complications:

  • Osteoporosis and bone fractures: Long-term use weakens the bones (glucocorticoid-induced osteoporosis), increasing your risk of fragility fractures [16][17]. Your doctor will assess your fracture risk when you start treatment and may prescribe calcium, Vitamin D, or specific bone-protecting medications [18][19][20].
  • Metabolic syndrome and diabetes: Prednisone can increase your blood sugar levels and blood pressure, potentially leading to diabetes or metabolic syndrome [21][22].
  • Eye complications: Steroids can increase the pressure inside your eyes (ocular hypertension) and potentially lead to glaucoma (damage to the optic nerve from elevated eye pressure) or cataracts [23][24][25].
  • Adrenal insufficiency: Over time, your body stops making its own natural stress hormones. If you stop taking prednisone suddenly, your body will not have enough of these hormones to function normally, which can cause a life-threatening adrenal crisis [26][27].

The Importance of Tapering

Because of the risk of adrenal insufficiency and to manage “rebound” inflammation, you should never stop taking prednisone suddenly [26][27]. Instead, your doctor will prescribe a tapering protocol, slowly reducing your dose over weeks or months [28][29]. Current best practices emphasize starting with lower initial doses (30 mg/day or less) and tapering rapidly to a low maintenance dose (5 mg/day or less) to minimize toxicity while keeping sarcoidosis under control [2][1].

Note on missed doses: If you accidentally miss a single dose, do not panic. Take it as soon as you remember, or skip it if it is close to your next scheduled dose. However, completely stopping the medication over several days can lead to an adrenal crisis, marked by severe fatigue, weakness, nausea, and vomiting [30][26].

If prednisone cannot be lowered without your sarcoidosis flaring up, your doctor may add a steroid-sparing agent. These are other medications (like methotrexate or infliximab) that help control the disease so you can safely lower and eventually stop your prednisone [31][32][33].

Required Monitoring

While on prednisone, you will need regular monitoring to catch side effects early [34]. This typically includes:

  • Regular blood pressure and blood sugar (HbA1c) checks to monitor for metabolic changes [34][35].
  • Bone density scans (DEXA) to monitor for osteoporosis [18].
  • Regular eye exams with an ophthalmologist to check your intraocular pressure and screen for glaucoma [23].

Common questions in this guide

Why do I need to taper off prednisone instead of just stopping?
Stopping prednisone suddenly can cause a life-threatening condition called adrenal crisis, where your body lacks enough natural stress hormones. Your doctor will prescribe a tapering plan to slowly reduce your dose to prevent withdrawal symptoms and sarcoidosis flares.
What are the long-term side effects of taking prednisone for sarcoidosis?
Long-term prednisone use increases the risk of osteoporosis, metabolic syndrome, diabetes, and eye complications like glaucoma or cataracts. Because of these risks, your doctor will monitor you closely and aim for the lowest effective dose for the shortest possible time.
Can I take ibuprofen or naproxen while on prednisone?
Combining prednisone with over-the-counter NSAIDs like ibuprofen or naproxen significantly increases your risk of serious stomach bleeding and ulcers. You should always consult your doctor before taking these pain relievers while on corticosteroid therapy.
What is a steroid-sparing agent?
A steroid-sparing agent is an alternative medication, such as methotrexate or infliximab, used to help control sarcoidosis. These are prescribed if you cannot lower your prednisone dose without symptoms flaring up, allowing you to safely reduce or stop taking steroids.
How can I manage sleep disturbances while taking prednisone?
Prednisone can disrupt your natural sleep cycle, causing insomnia or making it hard to stay asleep. Taking your daily dose with breakfast or before 9:00 AM can help minimize this disruption and make it easier to fall asleep at night.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.What is our specific timeline and target goal for tapering my prednisone dose?
  2. 2.Do I need a prescription bone-protecting medication, or is over-the-counter calcium and Vitamin D sufficient?
  3. 3.Should I be prescribed a stomach-protecting medication like a PPI if I occasionally need to take over-the-counter NSAIDs for pain?
  4. 4.What specific signs of infection or blood clots should prompt me to call the office versus going directly to the emergency room?
  5. 5.Am I a candidate for a steroid-sparing agent like methotrexate or infliximab to help me reduce my prednisone dose sooner?
