Overview
What is this medicine?
Rayos is a delayed-release form of prednisone, a type of steroid medication. It's designed to be taken in the evening so that the medicine starts working in the morning, helping to reduce morning stiffness and pain, especially for conditions like rheumatoid arthritis. It works by reducing inflammation and calming down your immune system.

Pharmacology
Mechanism of Action
Prednisone is a synthetic glucocorticoid that is converted in the liver to prednisolone, its active metabolite. Prednisolone exerts its anti-inflammatory and immunosuppressive actions by binding to intracellular glucocorticoid receptors. This complex then translocates to the nucleus, where it modulates gene expression, leading to the synthesis of anti-inflammatory proteins (e.g., lipocortin-1) and the inhibition of pro-inflammatory mediators (e.g., cytokines, chemokines, prostaglandins, leukotrienes). It also suppresses the immune system by inhibiting the function of lymphocytes and macrophages.

Special Patient Groups
Pregnancy
Prednisone is classified as Pregnancy Category C. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Corticosteroids have been shown to be teratogenic in animal studies.
Trimester-Specific Risks:
First Trimester:
Potential for increased risk of cleft palate in animal studies; human data are inconclusive but generally do not show a consistent pattern of major malformations.
Second Trimester:
Risk of fetal growth restriction, premature delivery, and adrenal suppression in the neonate with prolonged or high-dose use.
Third Trimester:
Risk of fetal growth restriction, premature delivery, and adrenal suppression in the neonate with prolonged or high-dose use. Neonates exposed to corticosteroids in utero should be carefully observed for signs of hypoadrenalism.
Lactation
Prednisone and its active metabolite prednisolone are excreted into breast milk. While generally considered compatible with breastfeeding at low to moderate doses, caution is advised. The lowest effective dose should be used, and the infant should be monitored for adverse effects.
Infant Risk:
L3 (Moderate risk). Potential for growth suppression, interference with endogenous corticosteroid production, and other adverse effects in the infant, especially with high doses or prolonged use. Consider taking the dose immediately after a feeding or waiting 4 hours after a dose before feeding to minimize infant exposure.
Pediatric Use
Safety and effectiveness of Rayos (prednisone delayed-release) have not been established in pediatric patients. Standard prednisone formulations are used in pediatrics, but long-term use can cause growth retardation, cataracts, glaucoma, and other systemic adverse effects. Careful monitoring of growth and development is essential.
Geriatric Use
Elderly patients may be at increased risk of adverse effects, including osteoporosis, hypertension, diabetes, fluid retention, and cataracts. Use the lowest effective dose and monitor closely for adverse reactions.
Clinical Information
Clinical Pearls
- Rayos is specifically formulated for delayed release, designed to be taken in the evening (e.g., 10 PM) to provide peak prednisone levels in the morning, which can be beneficial for conditions like rheumatoid arthritis with prominent morning stiffness.
- Patients should be instructed not to crush, chew, or split the tablets, as this will disrupt the delayed-release mechanism.
- Always emphasize the importance of not discontinuing corticosteroids abruptly due to the risk of adrenal insufficiency.
- Educate patients on signs of infection, as corticosteroids can mask symptoms and increase susceptibility.
- Long-term corticosteroid use requires monitoring for bone density, blood glucose, blood pressure, and ophthalmologic changes.
Alternative Therapies
- Immediate-release prednisone/prednisolone
- Other systemic corticosteroids (e.g., methylprednisolone, dexamethasone)
- NSAIDs (Non-steroidal anti-inflammatory drugs)
- DMARDs (Disease-modifying antirheumatic drugs) for rheumatoid arthritis (e.g., methotrexate, biologics)
- Immunosuppressants (e.g., azathioprine, cyclosporine)
Cost & Coverage
Average Cost:
$150 - $300 per 30 tablets (2mg)
Generic Available:
Yes
Insurance Coverage:
Tier 2 or Tier 3 (Brand-name Rayos may be higher tier than generic prednisone)
