If you are a seasonal allergy sufferer, or are diagnosed with the hives on a regular basis, your doctor may prescribe Xyzal to help relieve your symptoms. An antihistamine, Xyzal works by blocking the histamine in your body, thus reducing your symptoms. While a welcomed treatment for many, some may find its side effects outweigh its benefits.
Most Likely Side Effects
As with any medication, Xyzal produces side effects that are more common and less serious. If you experience any of these side effects, you should see them subside shortly after beginning your treatment. They include but are not limited to drowsiness, fatigue, coughing and sore throat. You may also become inflicted with the common cold, develop a fever or experience a sore throat. If these side effects do not go away or become worse, speak to your doctor. He may be able to adjust your dose or change your medication.
Severe Side Effects
Just as Xyzal produces mild side effects, it may also produce more severe side effects for which you should seek medical attention immediately as recommended by Drugs.com. These side effects include urine that is darker than usual, an irregular heartbeat or severe dizziness that does not go away. A yellowing of your skin or eyes could indicate a condition referred to as jaundice; this is sign of liver damage. Fainting is another reason to seek emergency help, as is a sudden change in your behavior, such as becoming hostile or agitated for no apparent reason. Xyzal also has the potential for causing seizures.
Overdose and Allergic Reactions
If you overdose on Xyzal, Drugs.com recommends calling your local poison control center immediately, or going to the emergency room. Signs of a Xyzal overdose include agitation, restlessness, irritability and extreme drowsiness.
You cannot predict whether an allergic reaction will take place. However if one does, it may be life-threatening and requires emergency medical attention as well. Signs of an allergic reaction to Xyzal include an unexpected swelling of your face, throat, lips and mouth, an unexplained rash, wheezing, difficulty breathing and difficulty swallowing.
