No ingredient in DayQuil is known to interact with benzonatate.
Benzonatate is a non-narcotic medication, commonly prescribed with antibiotics to decrease the frequency of coughing. It appears to have an anesthetic effect (locally in the respiratory tract) and may also work centrally in the brain to reduce the cough reflex.
Benzonatate has several potential drug interaction, including with:
- Opioid analgesics
- Blood pressure medications
- Monoamine oxidase inhibitors (MAOIs)
- CNS depressants
In terms of using with CNS depressants, indicated doses of benzonatate may cause sedation and dizziness, but is not known to cause respiratory depression.
Nevertheless, high doses may cause shallow breathing, which is why it should be used cautiously with CNS depressants (or other drugs that can cause shallow breathing, like opioids).
When it comes to the ingredients in DayQuil, there are no reported interactions with benzonatate.
SummaryThere is no known interaction between benzonatate and DayQuil (or DayQuil Severe).
