I know they are rare & usually mild but the main concern is allergic reaction or blood clots
& these are more about the person than the vaccine.
would taking an antihistamine or 2 & some aspirin for a few days before their jab help prevent this?
or at least lessen the reaction?
ive had all 3 of mine, but i'm just curious why they dont advise people to do this?
would it bring some people some 'peace of mind', or would that make scared people even more scared, and be taken as 'admitting' the vacc can cause problems?
Yes if you feel happier taking an antihistamine, the why not, but medically the allergic response that antihistamines combat is different from allergic responses to vaccination.
As for Aspirin, the same, no harm in taking one but after the vaccination rather than before, although I would prefer Ibuprofen before turning in at night.
I would avoid the Aspirin as it is one of the biggest triggers of mast-cell degranulation leading to non-specific histamine release which can cause idiopathic angioedema and can aggravate existing allergies or cause excessive reactions.
However there's nothing wrong with taking antihistamines prophylactically.
Alternatively you could chew two tablets of Piriton at the first sign of a reaction. Piriton is fast-acting but not long-lasting so you could chew another two tablets after a couple of hours if you feel the effects of the first dose wearing off.
