| What is the term for the unintended effects of a drug that commonly occur when a therapeutic dose of the drug is given? | Side effects |
| What is the term for the unintended effects of a drug that occur when the therapeutic dose of the drug causes severe or life-threatening effects? | Adverse effect |
