Grinite Thermal (Chlorphenamine Maleate, Dextromethorphan Hydrobromide, Pseudoephedrine Hydrochloride, Paracetamol)

Grinite Thermal is indicated for the temporary relief of multiple symptoms associated with common cold, influenza and related upper‑respiratory infections.

• Relief of cough caused by irritation of the throat or bronchial passages.
• Reduction of nasal congestion and sinus pressure through decongestion.
• Alleviation of headache, fever, sore throat and body aches.
• Management of runny nose, sneezing and itchy eyes related to allergic components.
• Support for overall comfort during mild to moderate cold or flu episodes.
• Assistance in reducing mild fever and improving sleep quality during illness.

The safety profile of Grinite Thermal reflects the combined actions of its four active ingredients. Most users experience mild, predictable effects, while rare serious reactions may occur.

Common

• Drowsiness or mild sedation.
• Dry mouth or throat.
• Nausea or mild stomach upset.
• Slight increase in heart rate or mild palpitations.
• Mild dizziness or light‑headedness.

Serious

• Severe allergic reaction such as rash, swelling, or difficulty breathing.
• High blood pressure or cardiac arrhythmia.

These effects are generally transient and resolve without medical intervention.

When considering Grinite Thermal, certain precautions should be observed to minimize risk and ensure appropriate use.

• Do not exceed the recommended daily dose; overdose can increase risk of liver toxicity from paracetamol.
• Use with caution in individuals with hypertension, heart disease, diabetes, or thyroid disorders due to pseudoephedrine effects.
• Avoid use if you have a known allergy to any of the four active ingredients.
• Consult a healthcare professional before use during pregnancy, breastfeeding, or in children under the recommended age.
• Limit concurrent use of other products containing similar ingredients to prevent duplication.

Grinite Thermal may interact with other medicines, affecting their efficacy or safety. Review the following interaction categories before combining treatments.

Avoid

• Monoamine oxidase inhibitors (MAOIs) or recent MAOI therapy, due to risk of hypertensive crisis with pseudoephedrine.
• Other cough suppressants or dextromethorphan‑containing products, which can increase the risk of serotonin syndrome.
• Additional paracetamol‑containing preparations, which may lead to excessive dosing and liver injury.

Use with caution

• Antihypertensive drugs, as pseudoephedrine may reduce their effectiveness.
• Certain antidepressants (SSRIs, SNRIs) because of potential additive serotonergic effects with dextromethorphan.
• Antihistamines or sedatives, which may enhance drowsiness caused by chlorphenamine.
