Be seen today
Call a poison information service promptly after a suspected overdose, even if there are no symptoms.
Have the medicine name, strength, estimated amount, time taken, age, weight, symptoms, and other medicines available if possible.
Seek same-day medical advice for persistent vomiting, marked swelling, worsening weakness, unusual mood changes, very high home blood sugar readings, or signs of infection.
Also get advice before changing or stopping a steroid that has been used regularly.
