History and ownership
BIOFLU is a brand within the portfolio of Unilab, a Philippine pharmaceutical company whose products include a wide range of prescription and consumer healthcare medicines.
Public Philippine intellectual property records identify UNILAB, Inc. as the applicant for a BIOFLU-related trademark application filed in 2024. The filing covers pharmaceutical preparations and uses the BIOFLU name together with descriptions of flu symptoms such as fever, colds, body pain, cough, sore throat, and headache.2
The Philippine Food and Drug Administration (FDA) has also included BIOFLU among registered and comparator pharmaceutical products, documenting the combination of its active ingredients.
Formulation
The standard BIOFLU Tablet contains three active ingredients:
Paracetamol (500 mg)
Paracetamol (acetaminophen) is an analgesic and antipyretic. In BIOFLU, it is used primarily to help reduce fever and pain, including symptoms such as headache and body aches.1
Phenylephrine HCl (10 mg)
Phenylephrine hydrochloride is a nasal decongestant. It works by reducing swelling and congestion in the nasal passages and sinuses, helping improve airflow and breathing through the nose. Unilab also describes it as helping reduce post-nasal drip.1
Chlorphenamine Maleate (2 mg)
Chlorphenamine maleate is an antihistamine that helps relieve symptoms such as runny nose, sneezing, and itchy or watery eyes.1
The formulation is designed to combine pain and fever relief, nasal decongestion, and antihistamine relief in a single medicine.
Indications
According to Unilab, BIOFLU is indicated for the relief of multiple symptoms, including:1
- Fever
- Body aches
- Headache
- Colds and runny nose
- Nasal congestion
- Sneezing
- Itchy or watery eyes
- Cough associated with post-nasal drip
- Sore throat associated with respiratory symptoms
The product is intended for symptoms associated with the common cold, allergic rhinitis, sinusitis, flu, and other minor respiratory tract infections.1 BIOFLU is primarily a symptom-relief medicine and does not function as an antibiotic for bacterial infections.
Mechanism of action
BIOFLU utilizes a multi-symptom formulation rather than targeting only one symptom. For individuals experiencing a combination of fever, headache, runny nose, and nasal congestion, the three components address these issues simultaneously:
- Paracetamol: Targets fever and pain
- Phenylephrine: Targets nasal congestion
- Chlorphenamine: Targets runny nose, sneezing, and allergy symptoms
Unilab states that the combination may begin taking effect in as fast as 15 minutes, although individual response can vary.1
Dosage and administration
For the standard BIOFLU Tablet, current product information states that adults and children 12 years and older may take one tablet every 6 hours, or as recommended by a doctor.1
BIOFLU also has formulations intended for younger children, including Children’s BIOFLU, with different dosing based on age. Dosage for pediatric variants should not be extrapolated from the adult tablet.1
Brand positioning and marketing
BIOFLU’s primary selling proposition is multi-symptom relief in a single product. Rather than positioning itself solely as a treatment for fever or nasal congestion, the brand emphasizes addressing several flu and cold symptoms concurrently. Official communication uses the Filipino-oriented positioning “Babangon ka sa BIOFLU!”, reflecting the concept of helping individuals recover their ability to continue normal daily activities despite flu symptoms.1
The brand has also utilized campaign hashtags such as #KayaAll and consumer-oriented campaigns like #ThankYouBioflu.1

Safety and precautions
Because BIOFLU contains paracetamol, an antihistamine, and a decongestant, consumers must monitor the ingredients in other medicines they are taking. Concurrent use of multiple paracetamol-containing products can unintentionally result in excessive intake.
Chlorphenamine may cause drowsiness in some individuals; users should exercise caution when engaging in activities requiring alertness. Appropriateness of use may also depend on existing conditions such as hypertension, cardiovascular problems, glaucoma, prostate or urinary issues, pregnancy, or concurrent medication use. Unilab specifically advises consumers to consult a doctor if symptoms persist.1
Product variants
The BIOFLU name extends beyond the standard adult tablet to encompass a broader product family. Unilab provides specific dosing information for Children’s BIOFLU liquid formulations for children aged 2–6 and 7–12 years.1 Consequently, “BIOFLU” may refer to either the specific standard tablet or the wider brand family.
Market context
BIOFLU occupies a distinctive position in the Philippine OTC market due to a brand identity strongly associated with “flu” and multi-symptom relief. Its combination of paracetamol, phenylephrine, and chlorphenamine allows for the management of several symptoms with a single tablet.
Marketing efforts are heavily localized for Filipino consumers, utilizing local terms such as lagnat (fever), sipon (colds/runny nose), and pananakit ng katawan (body pain).1
