Methylprednisolone Intravenous for Adults

Who can administer

May be administered by registered competent doctor or nurse/midwife

Check the approved route of administration on product packaging carefully (intravenous and depot intramuscular steroid preparations could be easily confused)

Solumedrone 40mg Act-O-Vial

Solumedrone 125mg Act-O-Vial

Solumedrone 500mg vial

Solumedrone 1g vial

500mg and 1000mg vial

40mg and 125mg Act-O-Vial reconstitution

Press down on plastic activator to force diluent into the lower compartment
Gently agitate to effect dissolution
Remove plastic tab covering centre of stopper - sterilise top of stopper with suitable germicide
Insert needle squarely through centre of plunger-stopper until tip is just visible. Invert vial and withdraw dose

Sodium Chloride 0.9% or Glucose 5%

Consider favouring sodium chloride 0.9% as the infusion fluid for high doses as administration glucose 5% may cause or aggravate hyperglycaemia

Slow intravenous injection (doses of 250mg or less)

Administer dose over at least five minutes (see below re adverse effects with rapid administration)

Intermittent intravenous infusion (may be used for all doses)

Administer required doses over at least 30 minutes
Rapid infusion may be associated with arrhythmias, cardiac arrest and circulatory collapse
The infusion volume is not critical - any infusion volume may be used
An infusion volume of as little as 50ml may be used if required (eg fluid restriction) but the residual volume in the infusion line must be flushed through at the same rate to avoid significant underdosing

Doses vary hugely depending on indication

Pulse therapy

Exacerbation of COPD

Give 125mg every six hours for 72 hours, then switch to oral therapy
Alternatively a dose of 0.5mg/kg every six hours for 72 hours, then switch to oral therapy

Acute spinal cord injury (within three hours of injury - but see below also)

Loading: 30mg/kg over 15 minutes
Maintenance: Wait 45 minutes after loading dose has been given, then start a continuous infusion of 5.4mg/kg/hour for 23 hours (multiple bags of 500ml required)
For patients who are initiated on treatment within 3 to 8 hours of injury, give loading dose and maintenance dose above, but continue maintenance infusion for 47 hours (rather than 23 hours)

For other indications: see SPC

Because rare instances of skin reactions and anaphylactic reactions have occurred in patients receiving corticosteroid therapy, appropriate precautionary measures should be taken prior to administration, especially when the patient has a history of drug allergy
Solumedrone is supplied as methylprednisolone sodium succinate (doses expressed in mg of methylprednisolone)
The 40mg vial used to contain lactose as an excipient- however this product has been reformulated to remove the lactose constituent since 2021
