FEXOFENADINE + MONTELUKAST

Fexofenadine: Fexofenadine is an antihistamine medication used to relieve allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat. It is commonly prescribed for allergic rhinitis (hay fever) and chronic idiopathic urticaria (chronic hives).

The mechanism of action of fexofenadine is to selectively block the effects of histamine in the body. Histamine is a substance produced naturally in the body during an allergic reaction, causing symptoms like itching, sneezing, and watery eyes. By blocking the histamine receptors, fexofenadine reduces or prevents these symptoms.

Fexofenadine is usually taken orally in the form of tablets or suspension. The usual recommended dose for adults and children 12 years and older is 180 mg once daily. For children 6-11 years old, the recommended dose is 30 mg twice daily. For children 2-5 years old, the dose is usually 30 mg once daily. It is advisable to follow the dosing instructions provided by the healthcare professional or mentioned on the product label.

While fexofenadine is generally well-tolerated, it may have some side effects. The most common side effects include headache, drowsiness, dizziness, fatigue, and dry mouth. These side effects are usually mild and temporary. Serious side effects are rare but may include allergic reactions, such as rash, itching, swelling, severe dizziness, or difficulty breathing. If any serious side effects occur, it is important to seek immediate medical attention.

Fexofenadine can interact with certain medications, so it is essential to inform your healthcare provider about all other medications, supplements, or herbs you may be taking.

Overall, fexofenadine is an effective and safe antihistamine used to manage allergy symptoms, but it is advisable to consult with a healthcare professional before starting this medication.

Montelukast: Montelukast is a medication used to help manage and prevent symptoms of asthma and seasonal allergies. It belongs to a class of drugs known as leukotriene receptor antagonists.

The main mechanism of action of montelukast is to block the action of leukotrienes, which are chemicals in the body that can cause inflammation in the lungs and airways. By inhibiting leukotriene receptors, montelukast helps to reduce inflammation, relax the muscles in the airways, and prevent the release of substances that cause allergy symptoms.

For asthma, montelukast is commonly prescribed as a daily maintenance treatment in both adults and children over the age of 12. It helps to control asthma symptoms and prevent asthma attacks when taken regularly. For seasonal allergies, montelukast can be used to relieve symptoms such as sneezing, runny nose, and itchy/watery eyes.

The usual dose of montelukast for adults and children over the age of 15 is 10 mg once daily. For children aged 6 to 14, the recommended dose is 5 mg once daily. For those aged 2 to 5, the dose is 4 mg once daily.

Like any medication, montelukast can cause side effects in some individuals. The most common side effects include headache, stomach pain, nausea, diarrhea, and cough. Some individuals may also experience behavioral changes such as agitation, irritability, sleep disturbances, and mood swings. Although rare, severe allergic reactions have been reported. If any unusual or concerning symptoms occur while taking montelukast, it is important to contact a healthcare professional for evaluation.
