DayQuil Cold & Flu is a multi-symptom relief medication, meaning it targets several symptoms at once. It contains a combination of active ingredients that work together to provide relief:

1. Acetaminophen (Pain Reliever/Fever Reducer):
   • Reduces fever and relieves minor aches and pains, such as headaches, sore throat, and body aches.
2. Dextromethorphan (Cough Suppressant):
   • Helps control coughing by acting on the part of the brain that triggers the cough reflex.
3. Phenylephrine (Nasal Decongestant):
   • Shrinks swollen blood vessels in the nasal passages, making it easier to breathe and relieving congestion.

By combining these ingredients, DayQuil addresses the most bothersome cold and flu symptoms, helping you feel better and stay productive during the day.

DayQuil is generally safe when used as directed, but it can cause side effects in some people. Most side effects are mild and go away on their own, but some may require medical attention.

Common side effects include:

• Nausea or upset stomach.
• Dizziness or lightheadedness.
• Mild headache.
• Dry mouth or throat.

Serious side effects (rare but possible):

• Allergic reactions (rash, itching, swelling, difficulty breathing).
• Fast or irregular heartbeat.
• Severe dizziness or nervousness.
• Liver damage (from excessive acetaminophen use).

If you experience any severe side effects, stop using DayQuil and contact your doctor immediately.

Before using DayQuil, consider the following precautions:

1. Allergies: Avoid DayQuil if you are allergic to any of its ingredients (acetaminophen, dextromethorphan, or phenylephrine).
2. Medical conditions: Inform your doctor if you have liver disease, high blood pressure, heart disease, thyroid problems, or diabetes.
3. Pregnancy and breastfeeding: Consult your doctor before using DayQuil if you are pregnant or breastfeeding.
4. Alcohol: Avoid alcohol while taking DayQuil, as it can increase the risk of liver damage and side effects.
5. Overdose risk: Do not exceed the recommended dose, as this can lead to serious health problems, including liver damage.

DayQuil may interact with other medications, which can increase the risk of side effects or reduce its effectiveness. Some common interactions include:

• Other acetaminophen-containing products: Taking too much acetaminophen can cause liver damage.
• MAO inhibitors (e.g., certain antidepressants): Can increase the risk of side effects from phenylephrine.
• Blood pressure medications: Phenylephrine may reduce the effectiveness of these drugs.
• Sedatives or alcohol: Can increase drowsiness or dizziness.

Always inform your doctor or pharmacist about all medications, supplements, and vitamins you are taking before using DayQuil.

The standard dosage for DayQuil Cold & Flu is:

• Adults and children 12 years and older: 2 liquiCaps or 30 mL of liquid every 4 hours as needed. Do not exceed 4 doses in 24 hours.
• Children under 12: Consult a doctor before use.

Always follow the instructions on the packaging or your doctor’s advice. If symptoms persist for more than 7 days or worsen, stop using DayQuil and consult a healthcare professional.
