Antihistamine Drugs

Antihistamine drugs are used to treat and prevent problems that occur when your body is out of whack. Most antihistamines are sold over-the-counter in your neighborhood drug store. What exactly is a histamine? They're the things in your body that react to dust, pet dander and other nasty stuff.  Your body pretty much reacts by sneezing, sniffling and drizzling unmentionables out of the nose. It can also trigger bouts of nausea and vomiting. Here are five drugs and what they do.

  1. Vicks NyQuil: This famous and very popular liquid antihistamine drug not only makes your allergies calm down, it puts you to sleep. Most people take a dose of NyQuil right before bed. It helps you rest better when you experience colds and allergies. However, be warned. This drug has both antihistamine and alcohol content. You can easily become too drowsy and unaware of your surroundings when taking NyQuil.
  2. Dimenhydrinate: You may not have heard of dimenhydrinate unless you suffer from nausea or motion sickness. If you become nauseous from the slightest smell or movement, dimenhydrinate may be for you. Traveling by airplane may trigger dizziness and nausea in some people. This antihistamine  helps in this case. It comes in tablet form.
  3. Benadryl: The famous Benadryl brand is designed to calm both itchiness and allergies. It comes in tablet, liquid, cream and dissolvable strip forms. The  drug works by attacking the problem at the source. Although there are products for kids, pregnant or nursing women should consult a physician before taking. The side effects and warnings include dizziness, lack of coordination and indigestion.
  4. Chlorpheniramine: This is one of the antihistamines you may hear about when you have severe hay fever, allergies or the common cold. It doesn't get rid of your problem, but it does, however, relieve the symptoms they cause. If your eyes look like you've been out all night, chlorpheniramine may help. The medication comes in all forms including liquid and capsule. Side effects may include dry mouth, loss of appetite and constipation.
  5. Loratadine: Loratadine has the same ingredients found in Alavert and Claritin. It can be taken as a liquid or tablet. The medication temporarily treats hay fever, hives and allergy symptoms. Unfortunately, it does not prevent skin reactions or allergies from beginning. Loratadine has severe drug reactions on its own. It can cause difficult breathing, swelling and even bring on the hives.

Antihistamine drugs may be prescribed by a doctor or purchased over-the-counter. It is best to ask for medical advice before taking any drug for the first time. Read all product labels before taking any type of medication. You don't want to take anything that isn't going to treat the right symptoms.
