Question explored with the scientific record
Prednidale is it safe
Prednisolone is a real drug with real, common side effects. "Safe" depends entirely on dose, duration, and who is taking it.
The honest answer is that prednisolone is a powerful steroid, not a benign one, and the evidence here shows harms that show up fast. In children given short courses of two weeks or less, the most common problems were vomiting (about 5 in 100), behavior changes (about 5 in 100), and sleep disturbance (about 4 in 100) [1]. More seriously, of 53 children tested for adrenal suppression, 43 showed it, meaning the body's own cortisol production was blunted [1]. Blood pressure rose in 144 of 369 children measured, about 39 in 100 [1].
In elderly patients, 37 in 100 developed steroid-induced high blood pressure within a week, and it appeared only at doses above 20 mg a day [2]. Older bodies also clear the drug more slowly, so exposure runs higher [5]. Psychiatric effects are documented too, including anxiety, agitation, insomnia, and paranoia, and one report suggested splitting the dose may reduce them [3].
| Group | Finding | Rate |
|---|---|---|
| Children, short course | Vomiting | ~5 in 100 [1] |
| Children, short course | Behavior change | ~5 in 100 [1] |
| Children tested | Adrenal suppression | 43 of 53 [1] |
| Elderly, first week | New high blood pressure | 37 in 100 [2] |
Where prednisolone is genuinely indicated, it can work. A trial in membranous nephropathy found far more remissions with prednisolone plus cyclophosphamide than supportive care alone, and better 10-year dialysis-free survival [4]. But that was a combination regimen in a specific kidney disease, not proof the drug is safe across the board.
This retrieval is thin on long-term safety, bone loss, and infection risk at typical outpatient doses. It cannot tell you the risk for your specific dose and condition.
My call: prednisolone is not "safe" in the casual sense. It is a drug to use at the lowest dose for the shortest time, with monitoring. Confidence: moderate.

Glucocorticoid-induced hypertension in the elderly relation to serum calcium and family history of essential hypertension
In a cohort of 35 elderly patients (over 65) treated with glucocorticoids, 37% developed steroid-induced hypertension within a week, with higher risk associated with daily prednisolone >20 mg and lower baseline serum calcium and/or a positive family history of essential hyperten…

Kinetics of prednisolone and endogenous cortisol suppression in the elderly
In elderly humans, prednisolone exposure after prednisone or prednisolone is higher due to reduced metabolic and renal clearance, yet cortisol suppression is attenuated, indicating age-related pharmacokinetic and pharmacodynamic changes.
