How Long Do the Side Effects of Cetrizine Last After Discontinuing It?

Q: Dear Doctor, for sinusitis, the doctor gave a levocetrizine 5mg tablet per day. I got very tired and felt mentally not well. So last week, I stopped that medicine. But since today, I feel weak in the evening. After how many days the side effect is gone?

Reply:

The side effects take 2 to 3 days to go. You may read here in detail about levocetrizine.

Take Care,
