Question : My blood pressure this morning was an average of 127/90 this morning, which is not normal. Should I go to the ER? I took dayquil this a.m. Could this raise BP?

Detailed Answer:
Hello.
Thanks for your follow up query..

Dayquil contains phenylephrine (treats nasal congestion) as one of its active ingredient, an alpha 1 adrenergic agonist which can increase your blood pressure especially diastolic pressure. But this is usually transient and the blood pressure returns to normal when the drug concentration decreases in the system because of its metabolism and elimination. Appropriate dosing and avoiding frequent use (advisable to use twice a day) should be enough to prevent the increase in BP.

Hope this answers your query. If any clarifications,don't hesitate to ask or else close this discussion and rate my answer. Take care. Wish you good health.
