Each TUE has a specific duration, at the end of which it expires automatically. Should you need to continue to use the prohibited substance/method, it is your responsibility to submit a new application for a TUE with updated medical information ahead of the expiry date, so that there is sufficient time for a decision to be made prior to the expiry of the current TUE.
Important Note
The presence (following sample collection), use, possession, or administration of the prohibited substance/method shall be consistent with the terms of your TUE. Therefore, if you require a materially different dosage, frequency,
route, or duration of administration, you should contact EGY-NADO, as you may be required to apply for a new TUE. Some substances and dosages, e.g., insulin, are often modified during treatment, and these possible fluctuations should
be mentioned by the treating physician in the TUE application and would usually be accepted by the EGY-NADO TUEC.
