What are Chlorphenamine Tablets & Solution?
Chlorphenamine Tablets & Solution are typically used to prevent and/or treat allergic reactions related to rhinitis (commonly referred to as 'hay fever').
Food allergies, insect bites, serum sickness and some forms of drug hypersensitivity can also be treated using Chlorphenamine Tablets & Solution.
This medication generally takes one of two forms: tablets or a solution. Both can be taken orally, though Chlorphenamine Solution can also be given as an injection. This medicine is available both over the counter and with a prescription.
The active ingredient in Chlorphenamine Tablets & Solution is chlorphenamine maleate. This ingredient is classified as an antihistamine.
Chlorphenamine Tablets & Solution are most often used to ease symptoms including an itchy or running nose, catarrh, skin irritation, swelling and redness.
How does Chlorphenamine Tablets & Solution work?
Respiratory allergies such as hay fever are most commonly triggered by airborne allergens, such as pollen, dust mites or pet hair.
Though usually harmless, your body may activate its natural defences when these allergens are detected by your immune system.
In the case of hay fever, this can result in symptoms such as a blocked/runny nose, watery eyes, itchiness (in the nose, eyes or mouth) and skin rashes.
Skin rashes can result from inhaling or ingesting such allergens, or through direct contact with the surface of your skin.
As an antihistamine, chlorphenamine maleate effectively blocks your body's H1-receptors, preventing your body from identifying (and, therefore reacting to) certain allergens.
You can obtain Chlorphenamine Tablets & Solution with or without prescription. However, it is recommended that you consult with your doctor before your first course of treatment.
You should also contact your doctor if your symptoms persist beyond 5 days.
