Yes, shoppers can deliver over-the-counter medications.
Certain states require that anyone purchasing over-the-counter medication with the ingredient dextromethorphan, primarily cold and flu medications, to be at least 18 years of age with a valid ID. These medications can include, but are not limited to, Vicks Dayquil and Nyquil, Mucinex DM, Theraflu, Delsym Children’s, etc.
If this is a requirement in your state, you'll be prompted to agree to terms and conditions at checkout, and your shopper will need to review your ID at delivery and collect a signature.
