@aisp3b I assume that your pharmacy will require a new prescription with orders for dilution. It is possible that your physician, or provider, won’t know this can be done. You can refer them to this:

A typical way to order this is to write an Rx for a compounded oral suspension of methylprednisolone at a defined concentration (e.g., 5 mg/mL or 10 mg/mL), with clear total daily dose, route, and duration.

Tell them you would prefer the 5 mg/ml as it will make it easier to take a low dose
