Here are some frequently asked questions about Asthafen Tablet, which contains Ketotifen as its active ingredient:

What is Asthafen Tablet used for?

Asthafen Tablet is primarily used for the prophylactic management of bronchial asthma, meaning it helps prevent asthma attacks. It is also prescribed for the symptomatic treatment of various allergic conditions, including allergic rhinitis (sneezing, runny nose), allergic conjunctivitis (itchy, watery eyes), skin rashes, and itching. It is important to note that Asthafen Tablet is not effective for treating acute asthma attacks that have already started.

How does Asthafen Tablet work?

Asthafen Tablet works through its active ingredient, Ketotifen, which acts as a non-competitive histamine H1-receptor antagonist and a mast cell stabilizer. This dual action means it blocks the effects of histamine, a chemical in the body responsible for allergic reactions, and also prevents mast cells from releasing other inflammatory substances. By doing so, it helps reduce the severity of allergic symptoms and prevents asthma attacks.

What is the usual dosage for Asthafen Tablet?

For adults and children 3 years of age and older, the typical oral dosage is 1 mg (one tablet) twice daily, usually taken with food, once in the morning and once in the evening. In more severe cases, your doctor may increase the dose to 2 mg twice daily. For children above 2 years, the usual dose is also 1 mg twice daily with food. If a patient is easily sedated, treatment might begin with 0.5 to 1 mg taken at night for the first few days. It is crucial to follow your doctor's specific instructions regarding dosage.

What are the possible side effects of Asthafen Tablet?

Common side effects can include drowsiness, dizziness, dry mouth, headache, stomach pain, nausea, fatigue, irritability, increased nosebleeds (with oral use), and trouble sleeping. In rare instances, more serious side effects like anaphylaxis, liver dysfunction, blood disorders, or seizures can occur. If you experience any severe or persistent side effects, you should contact your doctor immediately.

Is Asthafen Tablet safe during pregnancy or breastfeeding?

The safety of oral ketotifen, the active ingredient in Asthafen Tablet, during pregnancy and lactation is not well established, and it is generally not recommended for use during these periods.

Therefore, it's advised that you discuss the potential risks and benefits with your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

Can Asthafen Tablet be taken with other medications?

Asthafen Tablet can interact with other medications, potentially increasing drowsiness. This includes sedatives, hypnotics, other antihistamines, opioids, benzodiazepines, and antidepressants. Alcohol consumption should be limited as it can worsen drowsiness and dizziness. It may also interact with oral medications used for diabetes (oral hypoglycemic agents), and could affect the results of certain diagnostic allergy skin tests. Always inform your doctor or pharmacist about all prescription, over-the-counter, herbal, and vitamin supplements you are taking to avoid potential interactions.

What precautions should be taken while using Asthafen Tablet?

Since Asthafen Tablet can cause drowsiness and dizziness, exercise caution when performing tasks requiring alertness, such as driving or operating heavy machinery, especially during the initial stages of treatment. Alcohol intake should be limited or avoided. Inform your doctor if you have a history of medical conditions such as epilepsy, diabetes, or liver problems. This medication is not for immediate relief of asthma attacks; continue using your current asthma medications as instructed by your doctor and do not stop them abruptly when starting Asthafen Tablet.

What happens if a dose of Asthafen Tablet is missed?

If you miss a dose of Asthafen Tablet, 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 a missed one.
