A must-read for people with allergies: Allergens "lurk" in these medicines

We are all familiar with drug allergies. Many people are prone to allergies, so they will have allergic reactions after taking certain medicines. Let us now find out which medicines contain allergens.

Antipyretic drugs. When we have a cold or fever, we often take Chaihu oral liquid, Yinhuang oral liquid, etc. It should be noted that the above-mentioned oral liquids often contain alcohol. This is because ethanol is added during their preparation process to precipitate water-soluble impurities, which may induce alcohol allergy. Patients who are allergic to it may experience skin discomfort such as eczema and urticaria after taking it. In severe cases, it may lead to low blood pressure, suffocation, and even life-threatening. Patients who have not been found to be allergic to the above products should stop taking the medicine immediately if they experience the above discomfort and ask the doctor to rule out allergens. If the symptoms are severe, go to the hospital for treatment immediately.

In addition, common antipyretic and analgesic drugs such as acetaminophen and ibuprofen may be made into drops, to which certain pigments, saccharin, propylene glycol, etc. may be added. Although patients who are allergic to these ingredients are relatively rare, it is still recommended that you follow your doctor's advice to check whether you are allergic to them before use, and change the dosage form or type of medicine if necessary.

Vitamins. Vitamin A is often used for night blindness; Vitamin D has anti-rickets and other effects; Vitamin E can assist in the treatment of cardiovascular and cerebrovascular diseases, habitual abortion and infertility. However, these three vitamins are fat-soluble, so when they are made into drops, soft capsules, etc., some oils such as peanut oil, coconut oil or soybean oil are often added to facilitate human absorption. Therefore, patients who are allergic to peanuts, soybeans, coconuts, etc. must inform their doctors of their allergies before supplementing the above vitamins so that they can choose the type of medication that suits them.

Calcium supplement. Patients with osteoporosis often need to take calcium supplements, but calcium granules and calcium tablets often contain lactose. For people who are intolerant or allergic to lactose, it is best to check whether the product contains these ingredients before use to avoid allergic reactions or other adverse reactions when taking it.

Iron supplements. Starch, talcum powder and colorants are often added to iron supplements, granules and tablets. Pregnant women and patients with iron deficiency anemia who are allergic to these ingredients often experience symptoms such as itching and edema after taking them. Some patients who take iron supplements develop rashes all over their bodies after sun exposure. However, the above symptoms may also be adverse reactions caused by the iron supplement itself. Therefore, if symptoms such as itching and edema occur, it is recommended to seek medical attention promptly.

Folic acid. Women who are preparing to become pregnant, pregnant women, and people with high homocysteine ​​in their blood will take folic acid, but it may contain ingredients such as starch and lactose. Patients who are allergic to the above ingredients should read the instructions carefully before use. In addition, some rare patients are allergic to folic acid itself. If symptoms such as skin redness and itching occur after taking the medicine, it is recommended to stop taking it immediately and use anti-allergic drugs such as loratadine as prescribed by your doctor.

Topical medication. Many topical ointments, such as ketoprofen ointment for treating local pain caused by arthritis and keshangtong ointment for promoting blood circulation and removing blood stasis, contain alcohol. Patients who are allergic to alcohol should switch to alcohol-free dosage forms or types of medication under the guidance of a doctor.

Microecological preparations. For diarrhea caused by intestinal flora imbalance, some patients may use probiotic preparations such as Bifidobacterium and Lactobacillus triple live bacteria tablets. The skimmed milk powder, lactose, etc. contained in it can aggravate diarrhea symptoms in people with lactose intolerance or allergies. Therefore, people who are intolerant or allergic to lactose should read the instructions carefully to see if these ingredients are contained.

Finally, it should be reminded that patients with allergic constitution or a history of allergies should remember their allergens and fully explain their allergy history when seeking medical treatment. Before purchasing medicines, patients should consult a doctor and pharmacist, read the instructions carefully, and gain a preliminary understanding of the main ingredients of the medicines and their excipients. While taking the medicine, please pay close attention to your own changes and seek medical attention immediately if you feel unwell.
