Multi-Action Actifed Dry Coughs (Dextromethorphan Hydrobromide, Pseudoephedrine Hydrochloride, Triprolidine Hydrochloride)

Multi-Action Actifed Dry Coughs combines a cough suppressant, a nasal decongestant and an antihistamine to address symptoms of upper respiratory tract infections.

• Dry cough: suppresses the cough reflex to provide symptomatic relief.
• Nasal congestion: reduces swelling of nasal mucosa, improving airflow.
• Allergic rhinitis: blocks histamine receptors, alleviating sneezing and runny nose.
• Common cold symptoms: eases multiple discomforts such as cough, congestion and watery eyes.

• Dextromethorphan Hydrobromide acts as a sigma‑1 receptor agonist and NMDA receptor antagonist in the central nervous system, diminishing the cough reflex. Pseudoephedrine Hydrochloride is a sympathomimetic that stimulates α‑adrenergic receptors, causing vasoconstriction of nasal mucosal vessels and reducing congestion. Triprolidine Hydrochloride blocks H1‑histamine receptors, preventing the actions of histamine that lead to itching, sneezing and nasal discharge.

The combination may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Drowsiness: feeling of sleepiness or reduced alertness.
• Dry mouth: reduced salivation leading to thirst.
• Nausea: mild stomach discomfort or urge to vomit.
• Nasal irritation: mild burning or tingling in the nose.

Serious or Rare Side Effects

• Elevated blood pressure: significant rise that may require medical attention.
• Cardiac arrhythmia: irregular heartbeat, potentially life‑threatening.
• Severe allergic reaction: rash, swelling, or difficulty breathing.

Before using Multi-Action Actifed Dry Coughs, consider the following precautions.

• Pregnancy: consult a healthcare professional before use, as safety has not been established.
• Hypertension: avoid if you have high blood pressure due to pseudoephedrine’s vasoconstrictive effect.
• Glaucoma: use with caution, as decongestants may increase intra‑ocular pressure.
• Drug interactions: inform your doctor of all medicines, especially MAO inhibitors or other sympathomimetics.
• Age restrictions: not recommended for children under a specified age without medical advice.
• Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture.

Multi-Action Actifed Dry Coughs can interact with several medicines; awareness of major and moderate interactions helps ensure safety.

Major Interactions (Avoid)

• MAO inhibitors: risk of hypertensive crisis when combined with pseudoephedrine.
• Other CNS depressants: additive sedation when taken with alcohol or sedatives.
• Monoamine‑oxidase inhibitors: may amplify sympathomimetic effects.

Moderate Interactions (Monitor Closely)

• Antihistamines: increased drowsiness when combined with other H1 blockers.
• Antihypertensives: pseudoephedrine may reduce the effectiveness of blood‑pressure drugs.
• Antidepressants (SSRIs/SNRIs): potential for serotonin syndrome with dextromethorphan.
