The people interacting with patients don’t know which is which, but somebody does.
The whole point is seeing if the drug is better than a placebo, so you definitely need that information when it’s time to analyze data.

If someone got a placebo and experienced headaches but no one on the medication did do they still have to warn that the medication may cause headaches?

the study is setup so that the person taking the pill and the person giving it to the participant who is recording the results both don’t know whether the pill is a placebo, but some other person knows or it’s written somewhere else what the person got so in the end they can know if the result was from placebo. the important part is the researcher at the time of recording/interpreting doesn’t know, because if they know they may be bias in favor or against the placebo.
