Potassium Bromide

Serum levels of potassium bromide may take at least 125 days to stabilise due to the long half life of the drug.

Monitoring of therapeutic levels of potassium bromide can be assessed at any time post dosing.

Therapeutic levels for potassium bromide are 0.5 – 1.9 mg/mL. Young healthy dogs may tolerate levels up to 2.5 mg/mL and most dogs will tolerate levels up to 1.5 mg/mL.

SERUM GEL TUBES MUST NOT BE USED. EXTRA CARE IS NEEDED TO AVOID HAEMOLYSIS AS THIS SEVERLY ELEVATES THE RESULTS. SAMPLES MUST BE CENTRIFUGED AND SEPARATED BEFORE DESPATCH. WE SUGGEST THE USE OF LITHIUM HEP ARIN SAMPLES AS THIS ALLOWS IMMEDIA TE CENTRIFUGATION.

Potassium Bromide samples are reported with a haemolysis index where appropriate.
