What foods can you eat if you are allergic to drugs?

After a drug allergy, as long as you avoid foods that are clearly allergenic in themselves and have clear cross-reactions with the allergenic drugs, you can basically eat the rest of the foods you eat regularly without discomfort, and there is no need to blindly avoid large-scale foods.

Many people first stop eating eggs, milk, seafood, beef and mutton as soon as they are allergic. In fact, it is really not necessary. Unless you are allergic to these foods, skipping these foods will easily lead to nutritional deficiencies and slow down the recovery of the body. Not long ago, I met a girl in her early 20s at the allergy clinic. She was allergic to amoxicillin and had hives all over her body. When she came in, she asked me if she couldn't even touch the tea eggs cooked at home. When I asked her if she was okay with eating eggs and milk, I told her to eat. Instead, she put the spicy duck neck and ice sparkling wine she had just bought into the cupboard. After all, blood vessels in the skin and mucous membranes are in a state of expansion in the acute stage of allergies. Eating too spicy, too cold, or alcohol will only aggravate the symptoms of redness, swelling and itching, and whether the food itself can induce allergies is completely different.

As for the frequently asked question "Can you eat fermented foods if you are allergic to penicillin/cephalosporin?", there is currently no unified conclusion in the industry. Some allergists believe that penicillin is fermented by Penicillium. In the acute phase, eating blue cheese, fermented bean curd and other foods containing Penicillium may cause cross-reactions, so it is recommended to avoid them first.； Many clinicians also believe that the probability of such cross-reaction is extremely low. As long as there is no reaction after eating it, you can eat it normally. If you are not sure, just ask the doctor who is treating you directly. There is no need to worry about it yourself.

There is another point that is easily overlooked. If you are taking antihistamine anti-allergy drugs, it is best not to touch grapefruit or grapefruit juice. It will affect the liver's metabolism of the drug, which will either reduce the efficacy of the drug or may aggravate the side effects. There was a young man who drank grapefruit juice every day while taking medicine. The rash took almost two weeks to go away. After stopping the grapefruit juice, it was almost gone in 3 days. There was an old man who had a drug allergy. After his neighbor told him to avoid food, he only drank white porridge with vegetables every day. As a result, he became hypokalemic and felt weak all over within two days. I asked him to add the steamed lean meat and oranges that he usually eats back to his diet, and he recovered within two days.

To put it bluntly, there are really not as many dietary taboos as people think about drug allergies. Don’t add a bunch of unnecessary taboos to yourself. Just eat the food you usually eat and feel comfortable eating. If you are really not sure whether you can eat something, asking a doctor is much more reliable than searching the fragmented information on the Internet.
