This will help clean the bite and can prevent additional infection. It's best not to use other creams or medications on the bite area until it is clean. Look for over-the-counter antihistamines like Benadryl or Chlor-Trimeton. Don't scratch the bite, as that can cause it to become infected. Topical creams, gels, and lotions—particularly those containing pramoxine or benadryl—may help control itching. Make a cool compress, a cloth dampened with cold water or filled with ice, and hold it over the swollen area. If possible, elevate the bite area to reduce blood flow. Crops of raised, itchy, red bumps may appear as a result of a hypersensitivity to insect bites.  This usually occurs after bites with fleas, mosquitoes, and bedbugs.  Treatment for urticaria include antihistamines and topical steroids. Do not scratch these pumps, as this can result in scarring or infection. . Some insect bites can cause an allergic reaction, which can be very dangerous. The first signs of a serious reaction are often hives, rash, a swollen throat or tongue, and trouble breathing. This is an urgent medical emergency, so call 911 or go to the emergency room right away. Use an EpiPen if you have one, as allergic shock can be fatal. In most cases, the effects like itching and swelling can go away quickly. If the symptoms persist, or get worse, you should look for a doctor, to make sure you are not suffering from a more serious reaction. If you think, or know, you have been stung by a scorpion, seek medical attention immediately. Insect bites may not be dangerous by themselves, but many insects can carry diseases. Ticks can carry Lyme disease and Rocky Mountain spotted fever, and mosquitoes may carry West Nile Virus and encephalitis and can transmit these serious diseases to humans. Keep an eye out for other symptoms like fever, body aches, and nausea. These are usually signs of a more serious condition.
