Diabet Type II and HTN are not Contraindications of Prednisolon but me as a medical doctor not advise it in a patient like her.in regard to my colleagues with different openion.because some times we know a drug is not realy safe for our paitent but we make a choice between drugs benefits and drugs harms for him or her.we evaluate the value of using it and then make a decision.as you know prednisolon is one kind of corticosteroeids.and cortons in some issues are used as immune supressor.Diabetic patient have poor immune system already and using cortons make them more prepared for infections like systemic fungal infections!that they are some times very dangerous for diabetic peopls.in addition this patient is a middle aged lady with HTN.and prednisolon can increase her blood pressure more than what it is and it can influence on her blood sugar too and make it higher.
of course using prednisolon more than 3 month can occure or intensify some complaints like osteoprosis and delayed wounds healing.
but as I said some times scalepan of benefits are heavier than harms.so I suggest you to do a cansultation with an internist doctor for sure.
