Levocetirizine dihydrochloride is a type of medication known as an antihistamine and is used to treat seasonal allergies. Some of the most common side effects associated with the use of this medication include weakness, fatigue, and dry mouth. Inflammation of the nasal cavity may occur in some patients, and a potentially life-threatening type of allergic reaction known as anaphylaxis may occur in a small percentage of people taking this medication. The dosage of levocetirizine dihydrochloride may have to be adjusted and closely monitored in those with preexisting medical conditions such as kidney or liver disease. Any specific questions or concerns about the use of levocetirizine dihydrochloride in an individual situation should be discussed with a doctor or other medical professional.
Allergic rhinitis, more commonly referred to as hay fever, is a type of seasonal allergy that is commonly treated with levocetirizine dihydrochloride. Unlike other antihistamines, this drug does not cause sedation, although other side effects are possible. While the fatigue or weakness associated with the use of this medication is typically mild, any persistent or bothersome symptoms that begin after taking this drug should be reported to a doctor for further medical evaluation.
The nasal passages, throat, and mouth may become dry and irritated when taking levocetirizine dihydrochloride. If this occurs, drinking extra fluids may help to reduce the dryness. Extreme caution should be used when operating machinery or performing any task that requires intense focus or concentration, as this medication may cause drowsiness or vision problems for some people. Headache or heart palpitations may occasionally develop as a result of taking levocetirizine dihydrochloride and should be reported to a doctor.
Those with liver disease or impaired kidney function can usually take levocetirizine dihydrochloride, although the dosage may need to be adjusted. This medication is not generally recommended for children less than the age of six years, but it may be prescribed for infants as young as six months old in certain situations.
A severe allergic reaction to levocetirizine dihydrochloride is rare, but if symptoms do occur, the situation should be treated as a medical emergency. Symptoms of anaphylaxis may include itching, facial swelling, or difficulty breathing. Death may occur within a matter of minutes if the airway swells closed and oxygen is not able to reach the brain and other tissues of the body. Supportive care can begin on the ambulance, so it is best to call for emergency help instead of attempting to drive the affected patient to the nearest hospital.
