Before tooth extraction, you can use the medications you take on a daily basis Metypred, Equoral and Timohep without any changes. In most cases of dental procedures, local anesthetics are used, which do not have a systemic effect and do not affect the effectiveness and safety of other drugs used:

I encourage you to tell your dentist about all the medications you are taking. This will allow you to choose a safe agent for local anesthesia.
