Is It the Flu, a Cold, or Something Else?

Expert
Expert

Flu symptoms often appear suddenly and are more intense than those of the common cold

Is It the Flu, a Cold, or Something Else?

Flu, colds, COVID-19, and RSV share similar symptoms, but distinguishing them aids in treatment. Flu hits suddenly with high fever, body aches, dry cough, and fatigue, while colds develop gradually with milder symptoms like congestion and mild cough. 


COVID-19 can include fever and additional symptoms like loss of taste, diarrhea, or breathing issues. Respiratory syncytial virus (RSV) affects mostly infants and the elderly, causing wheezing and severe congestion. Observing the severity and combination of symptoms is crucial, especially for high-risk individuals.

How to Choose a Medicine for Flu - Buying Guide

Here are some tips from Dr. Eron Tan to help you choose the right flu medicine based on your symptoms, health condition, and lifestyle.

1

Safety First: Buy Only From FDA-Registered and Trusted Sellers

Expert
Expert
  • Buying from FDA-registered sources ensures the medicine is safe, effective, and not counterfeit.

  • Safety First: Buy Only From FDA-Registered and Trusted Sellers

    Whether you're buying flu medicine online or in-store, it’s essential to get them from legitimate and safe sources. Look for well-known pharmacies like Watsons or Mercury Drug, and choose official brand stores or verified sellers on Lazada and Shopee.


    To protect yourself from fake or recalled products, always do the following:

    • Check that the product is FDA-registered via the FDA Philippines Verification Portal

    • Visit the FDA Advisory Section to see if the item has been flagged or recalled

    • Review the expiration date, active ingredients, and warnings on the label

    • Avoid products with unclear packaging, no manufacturer details, or suspiciously low prices.

    2

    Start With the Right Treatment Approach Based on Your Symptoms

    Flu symptoms vary, so it’s best to match them with the right active ingredients to get faster relief and avoid overmedicating.

    Choose a Flu Medicine That Matches Your Symptoms for Faster Relief

    Expert
    Expert
    Not all flu medicines work the same. Choose one based on your specific symptoms to avoid taking unnecessary ingredients.
    Choose a Flu Medicine That Matches Your Symptoms for Faster Relief

    Treating flu effectively starts with choosing the right active ingredient for your symptoms.

    • Paracetamol: Used for fever and body aches. 
      • Adults – 500–1,000 mg every 4–6 hours, up to 4,000 mg/day.
      • Children (6–12 yrs) – 10–15 mg/kg every 4–6 hours, up to 4 doses/day.
    • Ibuprofen: Also relieves fever and pain.
      • Adults – 200–400 mg every 4–6 hours, max 1,200 mg/day (OTC).
      • Children – 5–10 mg/kg every 6–8 hours.
    • Chlorpheniramine: For runny nose and nasal congestion.
      • Adults – 4 mg every 4–6 hours, max 24 mg/day.
      • Children – 2 mg every 4–6 hours, max 12 mg/day.
    • Diphenhydramine: Another antihistamine for cold symptoms.
      • Adults – 25–50 mg every 6–8 hours, max 300 mg/day.
      • Children – 12.5–25 mg every 6–8 hours.
    • Phenylephrine: A decongestant for nasal congestion.
      • Adults – 10 mg every 4 hours, max 60 mg/day.
      • Children – 5 mg every 4 hours, max 30 mg/day.
    • Dextromethorphan: For dry cough.
      • Adults – 10–20 mg every 4 hours or 30 mg every 6–8 hours, max 120 mg/day.
      • Children – 5–10 mg every 4 hours or 15 mg every 6–8 hours.
    • Guaifenesin: Helps with cough with phlegm.
      • Adults – 200–400 mg every 4 hours, max 2,400 mg/day.
      • Children – 100–200 mg every 4 hours.

    Use Multi-Symptom Medicines Only When Necessary

    Expert
    Expert

    Multi-symptom medicines are helpful when you’re experiencing several symptoms, but they may contain ingredients you don’t need if your symptoms are mild or isolated.

    Use Multi-Symptom Medicines Only When Necessary

    Products like Neozep and Bioflu combine several actives in one tablet, which can be convenient when dealing with moderate to severe flu. 


    But if you only have one or two symptoms, it’s best to treat them separately. This helps you avoid overmedication, especially if you’re taking other drugs or supplements. Always check the label to prevent doubling up on ingredients like paracetamol.

    3

    Check if the Medicine Is Safe for Pregnancy or Other Health Conditions

    Some ingredients may not be safe for pregnant women or those with chronic illnesses. Always read the label and consult a doctor if needed.

    For Pregnant and Breastfeeding Women, Prioritize Doctor-Approved and Safe Ingredients

    Expert
    Expert

    Paracetamol is safe for mild symptoms, but some decongestants and pain relievers should be avoided. Always check with your doctor before taking any flu medicine.

    For Pregnant and Breastfeeding Women, Prioritize Doctor-Approved and Safe Ingredients

    If you're pregnant or breastfeeding, avoid self-medicating without a doctor's advice. Paracetamol is generally safe for fever and mild aches. But avoid NSAIDs like ibuprofen, aspirin, and decongestants like pseudoephedrine, especially in the first trimester


    Instead, use saline sprays, a humidifier, or warm teas with honey to ease congestion or a sore throat naturally.

    Be Cautious With Certain Ingredients if You Have Pre-Existing Conditions

    Expert
    Expert

    Those with hypertension, diabetes, or kidney issues should be careful with decongestants and NSAIDs. Read labels and talk to a doctor to avoid serious side effects.

    Be Cautious With Certain Ingredients if You Have Pre-Existing Conditions

    Certain ingredients can worsen pre-existing conditions. For example, pseudoephedrine and phenylephrine may raise blood pressure and should be avoided by those with hypertension. 


    If you have kidney issues, go for acetaminophen instead of NSAIDs. Diabetics should also check for sugar content in syrups and monitor blood sugar closely when taking corticosteroids or sweetened medicines.

    4

    Pick Between Drowsy and Non-Drowsy Formulations

    Expert
    Expert

    If you're unsure, take your first dose in the evening to test how your body reacts.

    Pick Between Drowsy and Non-Drowsy Formulations

    Some flu medicines include sedating antihistamines like diphenhydramine or chlorpheniramine, which can cause drowsiness. These are ideal if your symptoms—like a runny nose or cough—worsen at night and affect your sleep.


    For daytime use, look for non-drowsy options to avoid feeling sluggish. Always check the label before taking any flu medicine, especially if you plan to work, drive, or go to school. 

    5

    Consider Natural Remedies if You Prefer Gentler Alternatives

    Expert
    Expert

    Lagundi, honey, and warm teas can help relieve cough and sore throat. Just remember, these are supportive options—not substitutes for flu meds in high-risk cases.

    Consider Natural Remedies if You Prefer Gentler Alternatives

    Some people prefer to support their recovery with natural or herbal remedies, especially when symptoms are mild. Here are some safe and commonly used alternatives:

    • Lagundi (Vitex negundo): Helps clear mucus and ease cough

    • Honey: Reduces cough frequency and may work as well as some OTC cough syrups

    • Ginger or turmeric teas: Provide anti-inflammatory benefits for sore throat

    • Saline nasal sprays and warm water gargles: Help soothe congestion and discomfort


    While these remedies are generally safe, especially for children or those avoiding meds, they shouldn’t replace proper flu treatment for high-risk individuals, such as pregnant women, elderly adults, or people with chronic illnesses.

    When to Stop Self-Medicating and Consult a Doctor

    Expert
    Expert

    See a doctor if flu symptoms worsen or don’t improve after a few days. Delayed care can lead to serious complications like pneumonia or myocarditis.

    When to Stop Self-Medicating and Consult a Doctor

    Most flu symptoms improve within 3 to 7 days, but some cases require medical attention. If you're self-medicating and notice any of the following warning signs, it's best to stop and consult a doctor:

    • Fever lasting more than 3 days

    • Shortness of breath or difficulty breathing

    • Persistent chest pain or pressure

    • Dizziness, confusion, or fainting

    • Bluish lips or face

    • Severe dehydration (e.g., dry mouth, no urination)

    • Worsening of symptoms after initial improvement

    If you belong to a high-risk group, such as pregnant women, young children, seniors, or those with chronic illnesses like asthma or diabetes, don’t wait too long before seeking medical help.

    Frequently Asked Questions

    Below, Dr. Eron Tan answers common questions about managing flu symptoms and medication.

    How Soon Will Flu Medicine Take Effect?

    Most over-the-counter flu medicines take effect within 1 hour, especially those for fever and pain. Relief from congestion or cough may take a bit longer, depending on the active ingredients.

    Can Flu Medicine Shorten the Duration of the Illness?

    No, OTC flu medicines only relieve symptoms. If taken within 48 hours of symptom onset, antiviral drugs like oseltamivir may shorten the flu’s duration, but they require a prescription.
