Do You Need High Doses of Vitamin C for Urticaria Relief? - Internal Medicine

When dealing with urticaria (hives), the management of symptoms often involves a combination of antihistamines and dietary considerations. Your current regimen of Levocetirizine and Clarinase is a standard approach for alleviating allergic reactions and symptoms associated with urticaria. However, the suggestion to consume high doses of Vitamin C and B vitamins, particularly the recommendation of eating 12 oranges daily, raises several important points to consider.

Firstly, while Vitamin C is known for its antioxidant properties and potential immune-boosting effects, the idea that high doses are necessary for urticaria relief is not strongly supported by clinical evidence. The recommended daily allowance (RDA) for Vitamin C for adults is about 90 mg for men and 75 mg for women, with an upper limit set at 2,000 mg per day to avoid gastrointestinal disturbances and other side effects. Consuming excessive amounts of Vitamin C, especially in the form of supplements, can lead to side effects such as diarrhea, nausea, and abdominal cramps. Furthermore, while Vitamin C can help reduce oxidative stress, it is not a primary treatment for urticaria.

Regarding the consumption of B vitamins, these are also water-soluble and generally considered safe when taken within recommended limits. However, excessive intake can lead to adverse effects, particularly with certain B vitamins. For example, high doses of Vitamin B6 can lead to nerve damage, while excessive niacin (B3) can cause flushing and liver toxicity.

The suggestion to eat "natural foods" is generally beneficial, as a diet rich in fruits, vegetables, whole grains, and lean proteins can support overall health and potentially improve immune function. However, it is essential to balance this with the understanding that dietary changes alone may not resolve urticaria, especially if there are underlying allergic triggers or other medical conditions at play.

In terms of dietary recommendations, consider the following:
1. Balanced Diet: Focus on a variety of foods, including fruits and vegetables, lean proteins, whole grains, and healthy fats. This approach ensures you receive a broad spectrum of nutrients without the risk of excessive intake of any single vitamin.

2. Hydration: Staying well-hydrated can help your body manage symptoms more effectively. Water is essential for overall health and can aid in the elimination of toxins.

3. Identify Triggers: If certain foods seem to exacerbate your urticaria, consider keeping a food diary to identify potential allergens or irritants. Common culprits include shellfish, nuts, eggs, and certain preservatives.

4. Consult a Healthcare Provider: Before making significant changes to your diet or supplement regimen, it is crucial to consult with a healthcare professional. They can provide personalized advice based on your medical history and current symptoms.

5. Monitor Symptoms: Keep track of your symptoms and any changes in your condition as you adjust your diet or supplement intake. This information can be valuable for your healthcare provider in managing your treatment plan.

In summary, while Vitamin C and B vitamins play essential roles in health, high doses are not necessarily required for managing urticaria and could lead to adverse effects. A balanced diet, proper hydration, and professional guidance are key components in effectively managing your symptoms. Always prioritize evidence-based treatments and consult with your healthcare provider for tailored advice.
