When using Health Essentials Max Strength Cold & Flu, certain precautions should be observed to minimize risk and ensure appropriate use.

• Do not exceed the recommended daily dose; overdose of paracetamol can cause liver damage.
• Avoid use if you have uncontrolled high blood pressure, severe heart disease, or thyroid disorders.
• Consult a healthcare professional before use during pregnancy, breastfeeding, or if you have chronic medical conditions.
• Keep out of reach of children; accidental ingestion can be hazardous.
• Limit intake of other products containing paracetamol, phenylephrine or caffeine to avoid duplication.
• Do not combine with monoamine‑oxidase inhibitors or other strong stimulants without medical advice.

Health Essentials Max Strength Cold & Flu can interact with other medicines; awareness of these interactions helps prevent adverse effects.

Avoid

• Other oral decongestants containing phenylephrine or pseudoephedrine.
• Additional paracetamol‑containing products (e.g., pain relievers, combination cold medicines).
• Monoamine‑oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI.
• Certain antidepressants that increase serotonin (e.g., SSRIs, SNRIs) due to risk of serotonin syndrome.
• Strong CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin) that may raise caffeine levels.

Use with caution

• Anticoagulants such as warfarin, because paracetamol may affect clotting.
• Antihypertensive agents, as phenylephrine can counteract blood‑pressure lowering effects.
• Diuretics, which may increase the risk of low potassium when combined with phenylephrine.
• Herbal supplements containing ephedra or other stimulants.
• Alcohol, which can increase liver strain when combined with paracetamol.
