Understanding Allergic Reactions
Before discussing Allsym Tablet, it's helpful to understand allergic reactions. The immune system releases chemical messengers like histamine and leukotrienes when exposed to allergens.
- Histamine causes immediate symptoms like sneezing, itching, watery eyes, and a runny nose.
- Leukotrienes lead to inflammation and swelling, causing nasal congestion and breathing difficulties.
What is Allsym Tablet?
Allsym Tablet is a prescription combination medication that addresses allergic reactions using two active ingredients:
- Levocetirizine: An antihistamine that blocks histamine, reducing sneezing, itching, and runny nose. While generally non-sedative, it can cause drowsiness.
- Montelukast: A leukotriene receptor antagonist that blocks leukotrienes, decreasing inflammation in nasal passages and airways, thus easing congestion and improving breathing. It is also useful for allergy-related asthma symptoms.
This combination provides broad relief from allergy symptoms.
Primary Uses and Indications
Allsym Tablet is primarily prescribed for:
- Allergic Rhinitis: Treating seasonal and perennial allergies with symptoms like sneezing, runny nose, and itchy eyes.
- Chronic Urticaria (Hives): Relieving itching, redness, and swelling from chronic hives.
- Asthma Management: Long-term management of asthma symptoms by reducing airway inflammation, especially in those with allergic rhinitis. It is not for acute asthma attacks.
Administration
Follow your doctor's instructions precisely when taking Allsym Tablet.
- Method: Swallow the tablet whole with water, with or without food. Do not crush or chew.
- Timing: Often recommended in the evening due to potential drowsiness.
If a dose is missed, take it when remembered, but skip it if the next dose is near. Do not double the dose.
