I recall the first thing I heard in Micro Biology :
" anything one puts on their skin, or in their body - they can become allergic to.
This was repeatd a LOT in that class, other medical classes, Rotations and in the Main OR.
Baselines of a person ( or oneself) then anytime a new med is 'scripted , or used from OTC, reactions can occur.
Women are prone to yeast infections for example, just they way they are plumbed. Eat Yogurt, and other live cultures to help prevent.
Sounds like a Reaction to the meds to me as well. Benedryl is still the most Rx for this .
In my case, I took a Sinus Med with Aspirin [ASA], I went into Anaphalatic shock. Benedryl I always used for allergies anyway, still think it is the best Antihistamine. I ate a lot of Benedryl, and continued to with the high doses of meds to get me over all this. I was so swollen, hands like catcher's mitts, I could not wear my shoes, I could not get my legs into my jeans.
Mine hit me in about 5 min from time of injesting the Asprin. My Doc said, "sometimes the system says "Screw It"- I don't like
anymore - and reacts. In my case my system did not want Asprin.
Sometimes it take a little time to develop, I have a friends wife taking Cancer treatments, various meds, chemo...she has times she reacts...violently to meds.
Another good example is ladies and Make- up. A lady will 'break-out' and blame the make-up Mfg for changing the formula. No, more like - the system says it no longer wants that make-up product.
Yes, we hadAdlult patients that after time taking supplements, prescribed suppliments developed reactions. Some even 4 wks or so of being on something as "innocent" as Ensure...vitamin mineral supplemet. Same with kids taking supplements.
One has to look at the whole system. Including other meds, currently taking, or how long since stopping taking one. Takes time to get a med out of one's system.
Another thing to consider/ remember is Similar things...or ...' Parallels". For instance if a person develops a reaction to Seafood, most often they react to Iodine and Betadine...we asked this of patients in the Hospital...reason why folks are asked so many times, they do not think it is important, or they simply forget.
Works the other way too. Seen folks in the OR break out when Prepped with Betadine...note to chart to advise patient they may be allergic to Seafood. Consult Physician, Allergist for test when healed up from surgery. Just avoid seafood in the meantime...
I am way out of the loop now on some of this...the basic information given is right.
Two handy links to look up meds and check for compatability, reactions, and other information.
