How to Use Medicines Safely in the Philippines: OTC Drugs, Prescriptions, and Counterfeit Risks

Medicines can relieve symptoms, treat disease, and save lives—but only when the right product is used by the right person at the right dose. “Over the counter” does not mean risk-free, and a medicine that is safe for one person may be dangerous for another.

Know the active ingredient

Different brand names can contain the same active ingredient. Taking two products for colds, pain, or fever at the same time may accidentally double the dose. Before using a medicine, check the active ingredient, strength, dose, timing, maximum daily amount, warnings, and expiry date.

Combination cold products deserve special attention because they may contain paracetamol, antihistamines, cough suppressants, or decongestants in one tablet or syrup. If you already take any of those separately, ask a pharmacist before combining them.

Tell healthcare professionals everything you take

Keep a list or phone photos of prescription medicines, OTC products, vitamins, herbal remedies, and supplements. Share it with your doctor, dentist, and pharmacist. “Natural” products can cause side effects or interact with medicines, anesthesia, anticoagulants, contraceptives, and treatments for blood pressure, diabetes, seizures, or mental health.

Ask before using medicine if you are pregnant or breastfeeding

Some medicines cross the placenta or enter breast milk. Others are considered compatible depending on the dose, timing, and health condition. Do not assume that an herbal product is safer. At the same time, do not suddenly stop an essential prescription without professional advice, because untreated illness can also be harmful.

Use antibiotics only when prescribed appropriately

Antibiotics treat certain bacterial infections; they do not treat viruses such as most colds and flu. Using the wrong antibiotic can delay diagnosis, cause side effects, and contribute to antimicrobial resistance. Do not share antibiotics, use leftovers, or change the dose on your own.

Be cautious with pain relievers

Paracetamol can cause severe liver injury in overdose, including accidental overdose from multiple combination products. Nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen can increase the risk of stomach bleeding, kidney injury, and other complications in some people. Extra caution is needed with a history of ulcer or gastrointestinal bleeding, kidney disease, anticoagulant use, certain heart conditions, or pregnancy.

Avoid counterfeit and unregistered products

  • Buy from licensed pharmacies or reputable healthcare facilities.
  • Avoid products with broken seals, misspellings, suspicious packaging, missing batch details, or unusually low prices.
  • Do not buy prescription-only medicines from anonymous social media sellers.
  • Check whether a product has a valid Philippine FDA authorization through the Philippine FDA Verification Portal.
  • Remember that product registration does not mean a medicine is appropriate for your personal condition.

Store medicines correctly

Keep medicines in their original containers, away from heat, moisture, direct sunlight, children, and pets. A bathroom cabinet or hot vehicle may be unsuitable. Refrigerate only when the label or pharmacist instructs you to. Do not use medicine that has changed color, smell, or texture.

Recognize a possible serious reaction

Call emergency services or go to an emergency department for difficulty breathing, swelling of the face or throat, widespread blistering rash, fainting, seizure, severe confusion, suspected overdose, vomiting blood, or black tarry stools.

Five questions to ask a pharmacist

  1. What is this medicine for?
  2. How and when should I take it?
  3. What should I avoid while using it?
  4. Which side effects are expected, and which are emergencies?
  5. What should I do if I miss a dose or vomit after taking it?

Bottom line: Read the active ingredient, avoid duplicate dosing, disclose all products you use, and obtain medicines from trustworthy sources. When uncertain, ask a licensed pharmacist or physician before taking the product.
