The 4 mg/mL injection strength may be used for intralesional and soft tissue administration. Doses range from mg to 4 mg injected as a single dose at the appropriate site. For soft tissue and bursal injections a dose of 2 to 4 mg is recommended. Ganglia require a dose of 1 to 2 mg. A dose of to 1 mg is used for injection into tendon sheaths. Usually employed when condition to be treated is limited to 1 or 2 sites. Dosage dependent upon degree of inflammation, size, disease state, and location of affected area. Repeat doses may be given from once every 3 to 5 days to once every 2 to 3 weeks.
When you see your doctor, prepare for the visit by recording a calendar with exact dosing on exact days and list any relevant side effects for the time when you tried to cut back. This will help the doctor understand your needs. Also, ask for a tapering schedule. And ask about possible medications that can help ease hydrocodone withdrawal symptoms, such as clonidine. The symptoms that you describe seem to be related directly to the lowered doses, but you may have decrease dosage too quickly. Some doctors suggest a tapered dosing regime over the course of 3-4 weeks so that you don’t rush the process.
The first isolation and structure identifications of prednisone and prednisolone were done in 1950 by Arthur Nobile .    The first commercially feasible synthesis of prednisone was carried out in 1955 in the laboratories of Schering Corporation, which later became Schering-Plough Corporation , by Arthur Nobile and coworkers.  They discovered that cortisone could be microbiologically oxidized to prednisone by the bacterium Corynebacterium simplex. The same process was used to prepare prednisolone from hydrocortisone .
