  • It effectively provides relief from allergic symptoms such as sneezing, runny nose, itchy/watery eyes, nasal congestion, and reduces airway inflammation.
  • It is used as a maintenance treatment to prevent asthma symptoms and reduce exacerbations, but it is not meant for immediate relief of acute asthma attacks.

• Dosage and Administration:

  • Take ALERZEST FX TAB orally, with or without food, as directed by your doctor.
  • Do not crush, chew, or break the tablets; swallow them whole.
  • It is generally recommended to take this medicine at a fixed time each day for best results.

Here are frequently asked questions about ALERZEST FX TAB by ALLET LIFESCIENCES:

1. What is ALERZEST FX TAB used for?

ALERZEST FX TAB is a combination medication primarily used to manage symptoms associated with allergic rhinitis, commonly known as hay fever, and to prevent and treat asthma symptoms. It provides relief from symptoms such as sneezing, runny nose, itchy or watery eyes, nasal congestion, and can also help with chronic hives (urticaria).

2. How does ALERZEST FX TAB work?

ALERZEST FX TAB contains two active ingredients: Montelukast Sodium and Fexofenadine. Montelukast is a leukotriene receptor antagonist that blocks the action of chemical messengers called leukotrienes, which are involved in inflammation and mucus production in the airways and nose, thereby improving respiratory function. Fexofenadine is a second-generation antihistamine that blocks the action of histamine, another chemical messenger responsible for allergic reactions like sneezing, runny nose, and itchy eyes. By targeting both pathways, the combination offers comprehensive relief from allergic symptoms.

3. What is the usual dosage for ALERZEST FX TAB?

The typical dosage for ALERZEST FX TAB (which usually contains Montelukast 10 mg and Fexofenadine 120 mg) is once daily. It can be taken with or without food. The exact dose and duration should always be as advised by your doctor, as it can vary based on your condition and response to treatment. This medicine is generally prescribed for adults and adolescents aged 12 or 15 years and above.

4. What are the possible side effects of ALERZEST FX TAB?

Common side effects may include headache, nausea, dizziness, dry mouth, and abdominal pain. Other possible side effects are fatigue, drowsiness (though fexofenadine is generally considered non-drowsy, individual responses vary), cough, and nosebleeds. Most side effects are usually mild and resolve over time. If any side effects persist or worsen, consult your doctor.

5. Is ALERZEST FX TAB safe during pregnancy or breastfeeding?

During pregnancy, ALERZEST FX TAB should be used with caution, and only if clearly advised by your doctor, as there isn't extensive information on its use in pregnancy. Other antihistamines might be more suitable in some cases.

Regarding breastfeeding, while ALERZEST FX TAB is generally considered safe, minimal amounts of fexofenadine may pass into breast milk. It is advised to consult your doctor before taking it while breastfeeding to weigh the benefits against any potential risks to the infant.

6. Can ALERZEST FX TAB be taken with other medications?

ALERZEST FX TAB can interact with certain medications. For example, antacids containing aluminum and magnesium can reduce the absorption of fexofenadine, making it less effective. Montelukast may interact with medications like phenobarbital, rifampicin, erythromycin, ketoconazole, itraconazole, and posaconazole. It is crucial to inform your doctor about all other medicines, supplements, or herbal products you are currently taking to avoid potential interactions.

7. What precautions should be taken while using ALERZEST FX TAB?

Avoid consuming certain fruit juices (such as apple, orange, or grapefruit) close to taking the medicine, as they may reduce the effectiveness of Fexofenadine. Alcohol consumption should be done with caution, as it may increase drowsiness or other side effects. This medication is not intended for immediate relief of acute asthma attacks and should be used as a maintenance treatment. Exercise caution if you have liver or kidney disease, and dose adjustments may be necessary. If you experience dizziness or sleepiness, avoid driving or operating heavy machinery.

8. What happens if a dose of ALERZEST FX TAB is missed?

If you miss a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the missed one.

9. How should ALERZEST FX TAB be stored?

ALERZEST FX TAB should be stored at room temperature, typically between 20-25°C (68-77°F). Keep it in a closed, airtight container, away from excessive heat, moisture, and direct light, and out of the reach of children.
