If pills are left out of a container do they become less effective?

Question

im not talking about gelcaps, just regular prescription pills. if i leave one in a drawer for a few weeks, does it become less effective?

Answer 1

No problem since you left these pills in the dark.  Light, heat and humidity put many precriptions at risk for losing power, but being in a closed drawer is the same as being stored in a brown bottle.

Answer 2

no. not if only a few weeks.  keep pills away from heat and humidity.
