Indications & Clinical Uses

Morrisons Max Strength Cold & Flu combines phenylephrine, paracetamol and caffeine to address symptoms of the common cold and influenza.

  • Nasal congestion: reduces swelling of nasal mucosa, easing blockage.
  • Headache and fever: lowers body temperature and eases pain.
  • Minor aches and body aches: provides analgesic relief for muscle and joint discomfort.

How It Works

  • Paracetamol acts centrally to inhibit cyclooxygenase enzymes, reducing pain and fever. Phenylephrine hydrochloride is an α1‑adrenergic receptor agonist that constricts nasal mucosal blood vessels, decreasing congestion. Caffeine antagonises adenosine receptors, enhancing the analgesic effect of paracetamol and providing mild stimulant activity, which can improve alertness during illness.

Side Effects

Common Side Effects

  • Nausea: mild stomach upset may occur.
  • Dizziness: transient light‑headedness reported.
  • Insomnia: caffeine can interfere with sleep.
  • Dry mouth: reduced salivation is possible.

Serious or Rare Side Effects

  • Severe allergic reaction: rash, swelling, or anaphylaxis.
  • High blood pressure: phenylephrine may elevate systolic pressure.
  • Cardiac arrhythmia: irregular heartbeat in susceptible individuals.

Precautions & Warnings

Before using this product, consider the following safety measures.

  • Do not exceed the recommended daily dose: follow prescriber or label guidance.
  • Avoid use in uncontrolled hypertension: phenylephrine can raise blood pressure.
  • Use caution with other CNS stimulants: combined effects may increase heart rate.
  • Consult a healthcare professional if pregnant or breastfeeding: safety data are limited.
  • Store below 25°C: keep in the original pack, protect from moisture.

Avoid Interactions

Potential drug interactions should be reviewed with a healthcare professional.

Major Interactions (Avoid)

  • Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis.
  • Other decongestants (e.g., pseudoephedrine): additive vasoconstriction.
  • Anticoagulants (e.g., warfarin): increased bleeding risk with paracetamol.

Moderate Interactions (Monitor Closely)

  • CYP2E1 inhibitors (e.g., isoniazid): may raise paracetamol levels.
  • Central nervous system depressants (e.g., benzodiazepines): caffeine may mask sedation.
  • Alcohol: combined use can increase liver load and risk of hepatotoxicity.
