In mast cell we see our doctors prescribing over the limits on the bottle .This is done with medicines in which this has been proven to be safe -Phergan is NOT one of those drugs with which it is safe to do this .
BNF - British National Formulary
-which is the Doctors prescribing bible
-and is updated every 6 months
Mast cell patients - This is specific advice
Find that they can not be drowsy
Those that do find it improves with regualr dosing over 2 weeks
Antihistamines -can cuase fast heart rate - so if you have any known heart problems or EDS 3 then this side effect needs to be watched for
Phenergan is new to mast cell patients as its coming back into use .
Histamine -which this drug is stopping acting causes high pulse and due to fluid loss -high pulse for a period of time . So the balance with antihistamines is they imporove these effects so - heart rate should improve .
In those without known heart problems the ebnfit could outweigh the risks
becuase this drug has certain exceptions - people who MUST NOT have it - It is not availble OTC (over the counter ) in most countries .
The aim of this is to enable specific discussion of side effects and reduce the amount of scary misinformation online about mast cell drugs specifically .
