Between 2001 and 2008 there has been a large increase in kids age 5 and under ending up in emergency rooms after having ingested some of their parents medications.
Prescription medicines as opposed to non-prescription medicines made up the majority of the cases, and cases with opiod painkillers like oxcycodone having huge increases.
It's strange how comfortable we have become with these drugs lying about, and no doubt the huge increases in medications prescribed means more will be out there.
By habit, we tend to put these in the "medicine cabinet"...usually a small awkward shaped, unlock-able space above our bathroom sinks. Funny but experts will tell you that is probably the worst environment to store medications in. Its not secure for one, and all the heat and steam and moisture can help to shorten the lifespan of some medications.
Many kids today are used to taking pills or seeing friends take them for sickness or adhd, so for a little one to climb up and grab them is not such an unlikely scenario.
But if you have older children or teenagers, you are not out of the woods either, kids have been know to take their parents medications like oxycodone, or to steal it from their friends parents when they visit. They know that some pills can be used to get high, or to sell to other kids.
So I would suggest you find a place to lock up you medications, don't leave them out or lying around, where little hands, or stealing hands can get to them. Invest perhaps in a safe for your bedroom, for both your medicine and your jewelry.
Better safe than sorry.
