Because of its active ingredients working together synergistically, most people tend to feel immediate relief after taking dayquill which begs the question – do they simply just think they’re experiencing relief?

While there may be minimal side effects from taking DayQuil, prolonged use can lead to addiction through self medicating rather than healing.

Therefore if someone already having pre-existing medical conditions should probably wait start with consulting physician regarding the proper prescription and dosage amount one get sufficiently healed instead of relying on medicine that only advance remedy in dealing minor disease whiles suppressing more severe conditions that might need stronger treatments in future. If all goes well with consultation then anybody willing take dayquil would fear less about its negative impact
