Hi doctor,

I am a 29-year-old male. I am suffering from a food allergy. I consulted a dermatologist two months back, and he prescribed Fexofenadine, Levocetirizine, with Montelukast Sodium tablets. He advised me not to take tomatoes, onions, potatoes, and lemon. The medications are over. Still, I find some hives in my body. How long should I take the medicines? Is it curable? Can I recover even if I take tomatoes, onions, and potatoes? Can you help me?



Welcome to icliniq.com.

If you have an allergy to certain foods, you must be getting hives when you consume them. You might get hives within an hour of consuming those foods mentioned above. Are you getting hives when you take these foods? If yes, then you have to avoid them in the future completely.

Once your body develops an allergy to something, it remembers it forever. Whenever you take those foods, you will have hives. This is like, if you have an allergy to a wristwatch, you should stop using it. That is the only remedy for that. Similarly, if you have found out that you are getting hives after having these foods, you should stop eating them. I am afraid that allergy is not curable, but it can be controlled with medications.

Your dermatologist has given you the right anti-allergic pills. Are you on any other oral medications? Have you done any blood tests? How often do you get hives? Do you get swollen lips, eyes, breathing difficulty, or any joint pain?
