Medrol Dose Pack Prescription Order and Patient Instructions
The standard Medrol Dose Pack provides 21 tablets of 4 mg methylprednisolone (84 mg total over 6 days), but this is frequently underdosed for many inflammatory conditions and should be prescribed with caution regarding its limitations. 1, 2
Standard Prescription Order
Rx: Methylprednisolone 4 mg tablets
- Dispense: 21 tablets (1 dose pack)

Critical Clinical Limitations
The standard dose pack is significantly underdosed compared to guideline-recommended therapy for most inflammatory conditions. 4, 2
- The dose pack provides only 84 mg methylprednisolone (equivalent to ~105 mg prednisone) over 6 days 1, 2
- For optimal anti-inflammatory effect, guidelines recommend 40-80 mg methylprednisolone daily for 5-10 days for conditions like severe asthma exacerbations 4, 2
- For a 60 kg adult requiring 1 mg/kg/day prednisone equivalent, this equals approximately 48 mg methylprednisolone daily—double what the dose pack provides on Day 1 4, 2
- The dose pack provides only 105 mg prednisone equivalent total versus 300-600 mg that would be given with standard burst therapy 2
When to Prescribe Alternative Dosing Instead
For moderate to severe inflammatory conditions, prescribe methylprednisolone 32-64 mg daily as a single morning dose for 5-10 days, then taper over a similar period. 4, 2
- Severe asthma exacerbations: 60-80 mg/day for 3-10 days 4
- Sudden hearing loss: 48 mg/day for 7-14 days followed by taper 4, 3
- Polymyalgia rheumatica equivalent: 12.5-25 mg prednisone equivalent (10-20 mg methylprednisolone) daily 4
- Single daily dosing is preferred over divided doses for better compliance and potentially reduced adrenal suppression 2, 3
Patient Instructions for Standard Dose Pack
Take with food or milk to minimize stomach upset. 1
- Take tablets exactly as directed on the package—do not skip doses or stop early
- Take earlier in the day when possible to minimize sleep disturbance 3
- Swallow tablets whole with a full glass of water
Monitoring and Side Effects to Discuss
Monitor blood glucose more frequently if diabetic, as hyperglycemia is the most common adverse effect. 1, 3
- Common side effects: Elevated blood sugar, increased appetite and weight gain, increased thirst, facial flushing, sleep disturbances 1, 3
- Contact provider if: Severe mood changes, vision changes, severe abdominal pain, signs of infection, or blood sugar >300 mg/dL 1
- No taper is needed after the 6-day course for the standard dose pack 4
Important Caveats
Do not use the dose pack for maintenance therapy in chronic inflammatory conditions—it is designed only for short-term treatment of acute exacerbations. 1
- Oral administration is as effective as IV provided gastrointestinal absorption is intact 4, 2
- For patients requiring longer courses beyond 6 days, initiate calcium and vitamin D supplementation to prevent bone loss 1
- The dose pack was designed for convenience, not optimal therapeutic dosing for serious inflammatory conditions 2
