Since a placebo, by definition, does not contain an active substance in its composition (lactose is often used as a placebo substance), it cannot cause any harm. You can't die from a placebo overdose.
Here you can argue about the obviousness of the answer. As it was correctly noted, the key branch of placebo work is autosuggestion. That is, the drug itself in the aisles of pharmacokinetics can not bring harm,but since a person thinks that the drug has certain properties and effects on the body, that is, certain doses, which means that if he drinks a shock dose of the drug, the effect may be different. And it can all come down to the fact that a person may think that this is the effect of an overdose of the drug. Everything is at the level of autosuggestion, this does not affect everyone, so you need to be careful about the accuracy.
