Ibuprofen and DayQuil are drugs in different classes with different mechanisms of action. Ibuprofen is an NSAID. The main active ingredient in DayQuil is acetaminophen, an analgesic.DayQuil also contains other drugs to reduce common cold symptoms.
Both drugs are commonly taken OTC for pain, fever, and the common cold. However, they are FDA-approved for different indications.
For a common cold, DayQuil can be a more effective option. The combination of acetaminophen, dextromethorphan, and phenylephrine is better at alleviating the common cold symptoms. Along with reducing fever and pain, it also improves cough,bronchial irritation, and sore throat.
Ibuprofen can reduce pain and fever but is not helpful for congestion and runny nose.
On the contrary, when treating fever or pain due to other conditions such as arthritis, muscle pain, or menstrual pain, ibuprofen should be the drug of choice. It is more potent at treating inflammation, swelling, and pain.
DayQuil, a widely taken OTC brand, is highly effective in reducing the common cold and flu symptoms. It’s a combination medicine that contains active ingredients with different mechanisms of action to ease these symptoms.
DayQuil is available in various combinations and dosage formulations, such as capsules, solutions, and pills. There are different formulations of DayQuil that include a combination of active drugs:
