How Grilinctu works
- Natural substances like Histamine released in our body are responsible for allergies, such as sneezing or runny nose. Chlorpheniramine blocks the effect of these substances and provides relief in symptoms of a common cold.
- There are specific areas in the brain (cough centre), which, when activated, produces coughing. Dextromethorphan affects these areas and deactivates them, thus helps in relieving the coughing.
Interactions
Interactions with other medicines
- Grilinctus Dx Bottle Of 100ml Syrup should not be taken with a medicine called monoamine oxidase inhibitors (MAOIs) because it produces a condition called serotonin syndrome which is a life-threatening condition that can occur rapidly due to a build-up of an excessive amount of serotonin in the body. In the case of serotonin syndrome, a person may experience high body temperature, high blood pressure, fast heart rate, excitability, tremor (shakiness), and sweating. In such a situation, patients should rush to a nearby hospital.
- Grilinctus Dx Bottle Of 100ml Syrup should be used cautiously with other medicines like Codeine, Hydrocodone (used for cough) that cause drowsiness.
