Stopping 40 mg Prednisone After One Week
After only one week of 40 mg prednisone daily, you can stop abruptly without tapering—there is no need for a gradual dose reduction.
Why No Taper is Needed
The risk of clinically significant adrenal insufficiency is extremely low after just one week of treatment. The FDA label explicitly states that gradual withdrawal is recommended "if after long-term therapy the drug is to be stopped" 1. One week does not constitute long-term therapy.
Evidence Supporting Abrupt Discontinuation
Multiple high-quality studies in acute conditions demonstrate that tapering provides no benefit over abrupt cessation after short courses:
- A randomized double-blind trial showed no difference in relapse rates or adrenal suppression between patients receiving 8 days of 40 mg/day prednisone versus a tapering regimen 2
- Another double-blind study of 35 patients found that abruptly stopping after 10 days of 40 mg daily prednisolone showed no rebound asthma or adverse outcomes compared to tapering 3
- A prospective study confirmed no difference in relapse rates between non-tapering versus tapering courses after 8 days 4
When Tapering IS Required
According to the 2024 European Society of Endocrinology/Endocrine Society joint guideline, adrenal suppression should be anticipated in patients receiving more than 7.5 mg prednisone equivalent daily for more than 3 weeks 5. The 2013 EULAR guidelines similarly note that HPA axis suppression may occur with doses above 7.5 mg for more than 3 weeks 6.
Your one-week course falls well below this threshold.
Important Caveats
- Do not stop if you're still symptomatic from the condition being treated—consult your prescribing physician first 1
- If you have been on any corticosteroids in the recent past (within weeks to months), different rules may apply
- If you have underlying adrenal insufficiency or pituitary disease, special considerations are needed
Practical Approach
Simply stop taking the prednisone after completing your one-week course. No dose reduction schedule is necessary. Continue any other prescribed medications (such as inhaled corticosteroids if treating asthma) as directed.
