It’s possible to take an antihistamine for bed bug bites, but you need to be careful not to take too much. Bed bug bites are not dangerous, but if you get multiple bites, you may need medical attention. While you can treat these bites at home with over-the-counter hydrocortisone or a prescription antihistamine, you should see a doctor if you experience a severe allergic reaction.
Over-the-counter antihistamines work by blocking the production of histamine, which causes the bites to itch. However, they can cause drowsiness, so you should take them before going to bed. In addition to taking an antihistamine, you can apply a cold compress to the affected area. You should apply this for at least 20 minutes to reduce the itch.
The use of insecticides is effective in killing bed bugs. Neonicotinoids, for example, work by activating nicotine receptors in the nervous system of bugs. This disrupts their growth. However, you shouldn’t use insect repellents around small children. If you must use repellents, try using DEET. Another good way to protect yourself is to cover your bedposts with paraffin oil. If you have an infestation that is too severe, call a professional exterminator.
If you suspect that you may be allergic to a bedbug sting, you should get medical attention immediately. Anaphylaxis, or an allergic reaction, is a potentially life-threatening reaction. Symptoms of anaphylaxis include swelling and difficulty breathing. Antihistamines can slow the process and prevent anaphylaxis.
