MEDICATION - DRUG TREATMENT

NOTES

In most cases donor deferral for medication relates to the underlying illness for which the medication is prescribed. Therefore, to determine eligibility, the condition / disease and the medication must be taken into account. The name of the medication and the reason it has been prescribed must be known in order to make an informed clinical decision regarding a donor’s eligibility

In many cases traces of medication to which the recipient is exposed would not have an adverse impact. In specific cases medication use requires deferral because of its pharmacological properties

Check the relevant entry for the specific deferral periods after stopping the medication. Medication that requires females of childbearing potential to undergo a Pregnancy Prevention programme are teratogenic e.g. Valporate (Epilim) Medication that requires females of childbearing potential to take contraceptive medication or use highly effective contraception measures are proven or potentially teratogenic e.g. Topiramate (Topamax)

13. SPORADIC MEDICATION PRESCRIBED OR NON-PRESCRIBED

Sporadic self-medication with some drugs e.g. vitamins, aspirin, sleeping tablets, need not prevent a donation being accepted, providing the donor is fit and well. If the donor has taken drugs affecting platelet function, (aspirin or anti-inflammatory drugs) within the last 5 days or 48 hours respectively, the donation should not be used for the preparation of platelets

14. SEDATIVES

Assess the underlying condition. Medication alone may not contraindicate donation

It should be remembered that drugs bought over the internet from a non-Irish registered medical practitioner, are not subject to quality control, and may not contain the active ingredients that they claim to contain. They may also contain other ingredients that may lead to adverse reactions. Taking drugs purchased over the internet, should be a reason for deferral on donor and recipient safety grounds
