Chlorpheniramine Maleate–Phenylephrine FDCs
Context: The government has restricted all Chlorpheniramine Maleate–Phenylephrine FDCs for children below four years, citing potential health risks and safer alternatives.
About Fixed-Dose Combinations (FDCs)
- A Fixed-Dose Combination (FDC) is a pharmaceutical formulation containing two or more active pharmaceutical ingredients (APIs) in a predetermined fixed ratio within a single dosage form.
- Examples:
-
- Amoxicillin + Clavulanic Acid: Clavulanic acid inhibits bacterial enzymes that can destroy amoxicillin, enhancing its effectiveness.
- Rifampicin + Isoniazid: The combination is widely used in tuberculosis treatment to improve efficacy and reduce the risk of drug resistance.
About Chlorpheniramine–Phenylephrine FDCs
- Chlorpheniramine Maleate–Phenylephrine is an FDC commonly used in medicines for the symptomatic relief of cold and allergy-related symptoms.
- Key Composition:
-
- Chlorpheniramine Maleate: An antihistamine that helps relieve symptoms such as sneezing and runny nose.
- Phenylephrine Hydrochloride: A decongestant that helps reduce nasal congestion.
- Application: The combination is used to provide relief from multiple upper-respiratory symptoms, particularly nasal congestion, runny nose and sneezing.
Rationale for Restricting Chlorpheniramine–Phenylephrine FDCs
- Child Safety & Safer Alternatives: The combination poses potential risks in children below four years, while safer therapeutic alternatives are available for managing their symptoms.
- Regulatory and Public-Health Action: The decision follows recommendations of an Expert Committee and the Drugs Technical Advisory Board (DTAB) and has been issued under Section 26A of the Drugs and Cosmetics Act, 1940, in the interest of public health.
- Labelling Requirement: Manufacturers must prominently display the warning: “Fixed Dose Combination shall not be used in children below four years of age” on labels, package inserts and promotional literature.

Surge in H1N1 Infection
Context: The Indian Council of Medical Research (ICMR) has calrified that the Influenza A (H1N1) viruses currently circulating in the country belong to the A/Missouri/11/2025 (H1N1) pdm09-like virus strain.
About H1N1 Infection
- H1N1 is a subtype of Influenza A virus that causes seasonal respiratory illness and is commonly known as swine flu.
- H1N1 stands for Hemagglutinin 1, Neuraminidase 1.
- These names refer to two specific types of proteins found on the surface of the virus.
- Caused By: H1N1 infection is caused by the Influenza A(H1N1)pdm09 virus, which has become part of the seasonal influenza spectrum.
- Strains: The currently circulating Indian strain is A/Missouri/11/2025 (H1N1)pdm09-like, classified under clade 6B.1A.5a2a and subclade D.3.1.1.
- Transmission: The infection primarily spreads through respiratory droplets and aerosols from infected individuals and through contaminated hands or surfaces.
- Fatality: Severe H1N1 infection can cause complications such as pneumonia and respiratory distress, particularly among vulnerable groups, although most healthy individuals recover with appropriate care.
- During the 2026 monsoon surge in India, the overall case fatality rate (CFR) for H1N1 (swine flu) has dropped significantly compared to historical outbreak levels (which peaked near 8.5% in 2009–2010).
- Prevention: Annual influenza vaccination, respiratory and hand hygiene, avoiding crowded places when symptomatic, masking when appropriate and maintaining adequate hydration.
- Treatment: Most cases recover with rest, fluids and symptomatic care, while medical consultation is advised when symptoms persist, worsen or become severe; high-risk patients may require specific medical treatment.
- Vaccine Relevance
- Vaccine Match: ICMR stated that circulating H1N1 strains are well matched with vaccine strains recommended for the Northern Hemisphere, reducing concern over vaccine mismatch.
- WHO Role: The WHO annually recommends influenza vaccine strains for the Northern and Southern Hemispheres based on surveillance data from its global laboratory network.
