I understand managing your health with Hepatitis B can feel stressful, but please be reassured. Levocetirizine (found in Xyzal M) is generally safe to take if you have Hepatitis B. Unlike many medications, levocetirizine is primarily cleared by your kidneys rather than your liver, so it does not typically place extra strain on your liver. However, because combination medicines like Xyzal M may contain other active ingredients like montelukast, which is processed by the liver, it is always safest to check with your doctor first. They can confirm it is completely safe for your specific liver health.
