Your vet is correct with the 10 day check. We want to know early on how well the treatment is working. NO CHANGES need to be made at this check tho. Only at the 30 day test should increases, IF needed, be made. The testing schedule for this drug is 10-14 days after starting, 30 days after starting (2 weeks after the first one), and 90 days after starting IF all is going well. IF things maintain then your baby will be tested every 90 days from then on OR until you see signs that the cortisol is dropping too much or rising again.
