Fexofenadine Hydrochloride

FEXOFENADINE 

Overview:

Fexofenadine is a non-drowsy antihistamine used to relieve allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and hives. It works by blocking histamine, a chemical in the body that causes allergic reactions. Because it doesn’t usually cause drowsiness, it’s safe to use during the day and helps people stay comfortable and alert while managing allergies.

Classification: Second-generation antihistamine

Uses:

Fexofenadine  is used to relieve allergy symptoms like sneezing, runny or itchy nose, and itchy or watery eyes. It’s also helpful for people with hives, reducing itching and rash so the skin feels more comfortable. Overall, it helps manage everyday allergy problems without making you feel sleepy, allowing you to go about your day normally.

How it works:

Fexofenadine is a selective H1 histamine receptor antagonist. By blocking H1 receptors, it keeps histamine from triggering sneezing, itching, and a runny nose during allergic reactions. Because it doesn’t cross the blood-brain barrier significantly, it relieves allergy symptoms without causing drowsiness, allowing patients to stay alert while controlling their allergies.

Dosage: As prescribed by your doctor.

Side Effects:

• Headache
• Drowsiness
• Nausea or upset stomach
• Dizziness
• Dry mouth

Precautions:

If you’re taking Fexofenadine, be cautious if you have kidney problems or are pregnant or breastfeeding, and always let your doctor know about other medicines you use, especially antacids, since they can affect how well it works. Although it’s usually non-drowsy, some people may still feel a little sleepy or dizzy, so be careful with driving or operating machines until you know how it affects you.

Montelukast

Montelukast 10mg Tablet

Montelukast is a bioactive molecule belonging to the class of Leukotriene Receptor Antagonists (LTRAs). It is widely used for long-term management of asthma and allergic rhinitis.

Unlike rescue inhalers, Montelukast works by blocking leukotrienes—natural chemicals that cause airway inflammation, swelling, and tightening. This helps keep the airways open and improves breathing over time.

Main Applications

Asthma Prevention: Helps reduce the frequency and severity of asthma attacks in both children and adults.

Allergic Rhinitis: Relieves sneezing, runny nose, and itchy eyes caused by seasonal or perennial allergies.

Exercise-Induced Bronchospasm: Prevents chest tightness during or after physical activity.

Alternative to Steroids: Often used in patients who cannot tolerate inhaled corticosteroids or prefer alternatives.

How to Use Montelukast

Night Dose: For asthma or combined asthma-allergy treatment, it is best taken once daily in the evening.

Allergy Alone: When used only for allergies, timing may vary, but consistency is important.

Before Exercise: For exercise-induced asthma, take a dose about 2 hours before activity. Do not take extra doses if already on daily therapy.

Long-Term Use: This is a preventive medicine and should be taken regularly, even if symptoms improve.

Precaution

Mood Changes Warning: Some patients (especially children) may experience behavioral or mood changes such as irritability, anxiety, or vivid dreams. Report any unusual symptoms to your doctor immediately.

Not for Acute Attacks: Montelukast does not relieve sudden asthma attacks. Always keep a rescue inhaler (e.g., Salbutamol or Albuterol) for emergencies.

Aspirin Sensitivity: Avoid aspirin and NSAIDs (like Ibuprofen) if they trigger your asthma.

Liver Consideration: Inform your doctor about any liver disease, as the drug is metabolized in the liver.

Some Common Side Effects

Most side effects are mild and temporary:

Mild headache

Abdominal pain or indigestion

Fever or flu-like symptoms (more common in children)

Dizziness or drowsiness
