Reactine is a popular over-the-counter medication used to treat allergic reactions, particularly those caused by hay fever, dust mites, pet dander, and other environmental allergens. The active ingredient in Reactine is cetirizine, a histamine receptor antagonist that works by blocking the action of histamine, a chemical released by the body during an allergic reaction. By blocking histamine, Reactine helps to alleviate symptoms such as itching, sneezing, runny nose, and congestion.
How Reactine Works
When an allergen enters the body, it triggers the release of histamine, which binds to receptors on the surface of cells, causing blood vessels to dilate and leading to increased mucus production. Reactine works by selectively blocking the H1 histamine receptors, preventing histamine from binding and triggering an allergic response. This results in a reduction of symptoms, allowing individuals to breathe easier, reduce itching and sneezing, and alleviate other discomforts associated with allergic reactions.
Reactine Dosage and Administration
The recommended dosage of Reactine varies depending on age and severity of symptoms. For adults and children over 12 years, the typical dose is 10mg once daily, taken orally with or without food. For children between 6 and 12 years, the dose is 10mg once daily, or 5mg twice daily. It’s essential to follow the recommended dosage instructions and consult a healthcare professional if symptoms persist or worsen. Always read and follow the label instructions to ensure safe and effective use of Reactine.
| Age Group | Recommended Dosage |
|---|---|
| Adults and children over 12 years | 10mg once daily |
| Children between 6 and 12 years | 10mg once daily or 5mg twice daily |
Common Side Effects and Interactions
While Reactine is generally well-tolerated, common side effects may include drowsiness, dry mouth, and stomach upset. In rare cases, more severe side effects, such as anaphylaxis, can occur. It’s essential to consult a healthcare professional if any side effects persist or worsen. Reactine can also interact with other medications, such as sedatives, tranquilizers, and certain antidepressants, which may increase the risk of side effects. Always inform your healthcare professional about any medications you’re taking before starting Reactine.
Precautions and Contraindications
Individuals with certain medical conditions, such as kidney or liver disease, should use Reactine with caution and under the guidance of a healthcare professional. Pregnant or breastfeeding women should also consult their healthcare provider before taking Reactine, as its safety in these populations has not been fully established. Hypersensitivity reactions to cetirizine or other ingredients in Reactine are a contraindication to its use.
Can I take Reactine with other medications?
+It's essential to consult your healthcare professional before taking Reactine with other medications, as interactions can occur. Provide your healthcare professional with a list of all medications you're currently taking, including prescription and over-the-counter medications, vitamins, and supplements.
How long does it take for Reactine to start working?
+Reactine typically starts working within 1-2 hours after taking the medication. However, it may take up to 3-4 days to reach its full effect. If symptoms persist or worsen, consult your healthcare professional for further guidance.
In conclusion, Reactine is a reliable and effective medication for treating allergic reactions, with a well-established safety profile and minimal side effects. By following the recommended dosage instructions and consulting a healthcare professional if necessary, individuals can safely and effectively manage their allergic symptoms and improve their quality of life.
