Promethazine injection is used to relieve or prevent some types of allergy or allergic reactions. It works 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. It can sometimes close up the bronchial tubes (air passages of the lungs) and make breathing difficult.

Promethazine is also used to prevent and control motion sickness, nausea, vomiting, and dizziness. In addition, it may be used to help people go to sleep and control their pain or anxiety before or after surgery or other procedures.

Promethazine may also be used for other conditions as determined by your doctor.

This medicine is only available with your doctor's prescription.

Zafirlukast is a leukotriene (loo-koe-TRY-een) inhibitor. Leukotrienes are chemicals your body releases when you breathe in an allergen (such as pollen). These chemicals cause swelling in your lungs and tightening of the muscles around your airways, which can result in asthma symptoms.

Zafirlukast is used for chronic treatment of asthma, and to prevent asthma attacks in adults and children as young as 5 years old.

Do not give zafirlukast to a child younger than 5 years without a doctor's advice.

Zafirlukast may also be used for purposes not listed in this medication guide.
