While looking into more information regarding two fellow posters discussion from another thread on whether KC is a sociopath or merely someone suffering from ODD, I found some information regarding a medication, Clonidine, a name which I was not familiar with. Upon further research, I discovered this medication is also a brand name, Catapres, which is used to treat withdrawal symptoms from alcohol, smoking, heroin, ODD, (Oppositional Defiant Disorder), ADHD, high blood pressure, and hot flash symptoms associated with menopause. These pills are available in 1mg, 2mg and 3 mg dosage and all the tablets are scored, meaning they have a line through the middle, and can be cut in half. Warnings for this medication urge caution with alcohol use and the use of other sedatives. These pills are tiny and could easily be administered to a small child. Not trying to refute everyone else's theory on the butter knife, but it certainly could have been used to score these tablets.
I originally thought maybe KC was dosing Caylee with some sort of codeine cough medication that she may have received following her alleged bruised rib, if a cough indeed led to a bruised rib. I have also considered the readily available OTC cough meds and benadryl. I am now leaning toward the use of prescription medication, although possibly with a mixture of OTCs.
We know hypertension is rampant, and we know CA was complaining of hot flashes and inability to sleep brought on by menopausal or at least perimenopausal symptoms. CA being a nurse could make her more likely to forgo hormonal replacement therapy and opt for a "safer" alternative to ease her symptoms. This is an older well studied medication and apparently is often prescribed in conjunction with other hypertensive medications.
My vote is for Catapres, or another antihypertensive agent, as we know GA took this type of medication while at the motel. Thoughts anyone?
