Normogrip Antitusivo Junior (Chlorphenamine Maleate, Dextromethorphan Hydrobromide, Paracetamol)

Normogrip Antitusivo Junior, a pediatric cough and cold relief formulation, addresses several upper respiratory conditions.

• Cough: reduces the cough reflex and provides symptomatic relief in children.
• Fever: lowers elevated body temperature associated with viral or bacterial infections.
• Mild pain: alleviates headache, sore throat or muscle aches commonly accompanying colds.
• Allergic rhinitis: diminishes nasal congestion, itching and watery discharge caused by allergens.
• Upper respiratory tract infection symptoms: eases a combination of cough, fever, pain and nasal irritation.

• Dextromethorphan acts as a sigma‑1 receptor agonist and an NMDA receptor antagonist, suppressing the cough centre in the brainstem. Chlorphenamine blocks H1‑histamine receptors, reducing histamine‑mediated nasal and airway inflammation. Paracetamol inhibits central cyclo‑oxygenase enzymes, decreasing prostaglandin synthesis to produce analgesic and antipyretic effects. The three agents work together to control cough, relieve pain and fever, and mitigate allergic symptoms.

Common and serious adverse reactions have been reported with the combination of chlorphenamine, dextromethorphan and paracetamol.

Common Side Effects

• Drowsiness: mild sedation or sleepiness, especially in younger children.
• Dry mouth: reduced salivation leading to throat discomfort.
• Nausea: upset stomach or feeling of queasiness.
• Rash: mild skin irritation or erythema.

Serious or Rare Side Effects

• Allergic reactions: hives, swelling or anaphylaxis requiring immediate medical attention.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Respiratory depression: markedly slowed breathing if excessive dextromethorphan is taken.

When using Normogrip Antitusivo Junior, several safety considerations should be observed.

• Age limitation: intended for pediatric use as directed by a healthcare professional.
• Allergy: avoid if the child has known hypersensitivity to chlorphenamine, dextromethorphan, paracetamol or any excipients.
• Liver function: use with caution in children with hepatic impairment.
• Drug interactions: review all concomitant medicines, especially other central nervous system depressants.
• Dosage: follow the prescriber’s instructions and do not exceed the recommended amount.
• Store at ambient temperature: keep in the original container, protect from moisture and light.

Normogrip Antitusivo Junior may interact with other medicines; awareness of major and moderate interactions helps ensure safe use.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): concurrent use can precipitate serotonin syndrome with dextromethorphan.
• Other paracetamol‑containing products: combined use increases risk of hepatotoxicity.
• Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may raise dextromethorphan plasma levels.

Moderate Interactions (Monitor Closely)

• Additional antihistamines: may cause additive sedation or anticholinergic effects.
• Central nervous system depressants (e.g., codeine, benzodiazepines): can enhance drowsiness and respiratory depression.
