When considering the discontinuation of antihistamines, such as the one you mentioned (likely referring to a brand like Desloratadine or similar), after two years of use, it's essential to approach this decision with caution and awareness of your body's response. Antihistamines are commonly used to manage allergic reactions, and while they can be effective, long-term use may lead to concerns about dependency or tolerance.

First, it’s important to note that antihistamines, particularly the second-generation ones, are generally considered safe for long-term use. However, the gradual reduction in dosage that you have already initiated—reducing from daily use to four doses per week—is a prudent approach. This tapering method can help your body adjust to lower levels of the medication and minimize any potential withdrawal symptoms or rebound allergic reactions.

Given that you have been symptom-free (no itching) while on a reduced dose, this is a positive sign that your body may be managing without the medication. However, it is crucial to consider the underlying condition that led to the initial prescription of the antihistamine. If your allergy symptoms were primarily due to a specific trigger that has since been resolved or is no longer present, it may be feasible to stop the medication altogether.
Before making a final decision to discontinue the antihistamine, consider the following steps:
1. Consult Your Healthcare Provider: It’s always best to discuss any changes in medication with your healthcare provider, especially since you are also taking Carbimazole to manage thyroid hormone levels. Your doctor can provide personalized advice based on your overall health and any potential interactions between your medications.

2. Monitor Symptoms: If you decide to stop taking the antihistamine, do so while closely monitoring for any return of allergy symptoms. Keep a diary of any changes in your condition, noting any itching or other allergic reactions that may arise.

3. Consider Environmental Factors: Sometimes, allergies can be influenced by environmental changes. If you have recently moved, changed your diet, or altered your exposure to allergens, these factors could also play a role in your symptoms.

4. Alternative Management Strategies: If you find that your symptoms return after stopping the antihistamine, consider discussing alternative management strategies with your healthcare provider. This could include lifestyle changes, dietary adjustments, or other non-pharmacological interventions.

5. Gradual Discontinuation: If you decide to stop taking the antihistamine, consider doing so gradually. You might reduce the frequency further before stopping completely, allowing your body to adjust.

In summary, while it is possible to stop taking antihistamines after two years of use, especially if you have been symptom-free while tapering the dose, it is crucial to do so under the guidance of a healthcare professional. They can help ensure that you are making the best decision for your health and can provide support should any symptoms re-emerge. Always prioritize open communication with your healthcare provider regarding any changes in your medication regimen.
