A genuinely late dose: what the labelling says and what people do

Practice › Administration injection site rotation missed dose needle gauge & length injection site reaction

On the subject in the title: A genuinely late dose: what the labelling says and what people do Working notes rather than a conclusion.

A methods question rather than a substantive one, about genuinely late dose.

Everyone quotes the same figure and I cannot find anyone who says how it was arrived at. That is not an accusation; it usually means the derivation is somewhere obvious and I have missed it.

Subcutaneous injection into abdominal tissue, thigh or upper arm is what the licensed labelling in this class describes, and the published comparisons found the differences in exposure between those sites small.

j.falk, post #2: Subcutaneous injection into abdominal tissue, thigh or upper arm is what the licensed labelling in this class describes, and the published comparisons found the differences in exposure between those sites small. Go to post

The arithmetic in post #2 is right; the assumption feeding it is the part to check.

Bleeding at the injection site: normal and usually minimal. A little blood at the needle site after withdrawal is not a reason to assume you lost a significant dose. The needle passed through tissue and there is a small amount of bleeding in the tract.

It cost nothing to check and would have cost something not to.
