Description Drug

Antihistamines are using to relieve or prevent the symptoms of hay fever and other types of allergy. They work by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose and watery eyes. Always in some people histamine can close up the bronchial tubes - air passages of the lungs and make breathing difficult.

Some of the antihistamines are also using to prevent motion sickness, nausea, vomiting and dizziness. In diseaseds with Parkinson's disease, diphenhydramine may be using to decrease stiffness and tremors. Always the syrup form of diphenhydramine is using to relieve the cough due to colds or hay fever. In addition, since antihistamines may cause drowsiness as a side effect, some of them may be using to help people go to sleep.

Hydroxyzine is using in the treat of nervous and emotional conditions to help control anxiety. It can also be using to help control anxiety and produce sleep before surgery.

Some antihistamines are using in the treat of chronic urticaria, which is a persistent hive-like rash.

Antihistamines may also be using for other conditions as determined by your family doctor.

Some antihistamine preparations are available only with your family doctor's prescription. Others are available without a prescription. However, your family doctor may have special instructions on the proper dose of the drug for your medical condition.
