• Follow Dosage Instructions: Always adhere to the dosage instructions on the label. Do not take more than the prescribed dosage.
• With or Without Food: You can take Duraflu with or without food. Take it with food if you experience stomach discomfort.

• Stay Hydrated: Drink lots of fluids when taking Duraflu, particularly with sore throat or congestion.

Duraflu has a combination of active ingredients that work at the same time to treat different symptoms of flu or cold:

• Acetaminophen: It is an antipyretic and analgesic which treats headache, body pain, and fever.
• Diphenhydramine: An antihistamine that blocks sneezing, watery eyes, and itching caused by colds or allergies. It also has a sedative effect that can be useful in inducing sleep.
• Pseudoephedrine: A decongestant that narrows the blood vessels in the nasal passages, decreasing swelling and dilating the passages.
• Dextromethorphan: A cough suppressant that decreases the urge to cough by affecting the brain impulses that produce the coughing reflex.

By mixing these ingredients, Duraflu alleviates a number of symptoms of respiratory infections.

Duraflu is safe when used as directed, but certain individuals might experience side effects:

• Drowsiness: Drowsiness is a frequent side effect of diphenhydramine (an antihistamine). This makes it hard to remain awake and concentrate.
• Dizziness: Dizziness or fainting may occur in some individuals.
• Dry Mouth or Throat: Duraflu produces dryness of the throat and mouth based on what type of antihistamine it has.
• Nausea or Stomach Disturbance: Some patients can experience nausea or stomach disturbance.
• Increased Blood Pressure: A decongestant pseudoephedrine raises blood pressure in certain patients; hence, an increased blood-pressure patient has to be cautious.

If you have any severe side effects like shortness of breath, rash, or swelling of the face or throat, discontinue the use of Duraflu and consult a doctor immediately.

Before using Duraflu, observe the following warnings and precautions:

• Pre-existing Medical Conditions: If you have any pre-existing medical conditions like liver disease, kidney disease, hypertension, or heart disease, consult a doctor before using Duraflu.
• Pregnancy and Lactation: Consult a doctor before taking Duraflu during pregnancy or lactation because some of the ingredients of Duraflu might not be appropriate during pregnancy or lactation.
• Avoid Alcohol: The use of alcohol with Duraflu can increase the sedative effect of Duraflu, causing drowsiness or dizziness. The consumption of alcohol is not recommended during treatment.
• Children: Duraflu must not be administered to children below 12 years of age except under the advice of a medical doctor. Proper dosage procedure must always be followed in children.
• Driving and Machine Operation: Avoid driving or any task that requires alertness as Duraflu has the tendency of causing drowsiness. Avoid using vehicles or heavy machinery until you are able to determine how the drug will affect you.

• Alcohol: Alcohol consumption during treatment with Duraflu may enhance the risk of side effects like drowsiness and dizziness. Alcohol intake should be avoided during treatment.
• Other Drugs: When taking other drugs for cold, flu, or aches, take extra precautions not to use more than one drug that has acetaminophen or diphenhydramine in it at the same time in case of accidental overdose.
• Blood Pressure Medications: If you take medication for high blood pressure, speak with your doctor first before taking Duraflu since pseudoephedrine increases blood pressure in certain individuals.

• Initial Dosage: The typical dosage is normally 1 to 2 tablets every 4 to 6 hours but not more than 4 doses in 24 hours.
• Adjustments: If you are drowsy or dizzy, reduce the dosage or take the medication at night. In case of any doubt in terms of dosage, consult a medical practitioner.

• Duraflu is an over-the-counter drug and does not need a prescription. But if you have any medical condition, are on some other medication, or are not certain if you can use Duraflu, it is always wise to take your doctor’s advice before taking the drug.
