Warnings and Precautions of Xolair Injection

Warnings:

Some people have experienced severe, life-threatening allergic reactions to Xolair, either immediately after the injection or hours later. It’s possible to have an allergic reaction even if you’ve been using Xolair regularly for more than a year.

If you show any signs of an allergic reaction to Xolair, such as hives, rash, anxiety, flushing, feeling faint, chest tightness, wheezing, difficulty breathing, rapid or weak heartbeat, or swelling of your face, lips, tongue, or throat, seek emergency medical help immediately.

Asthma often requires treatment with various medications. Always follow your doctor’s instructions and read the guides provided with each medication. Do not alter your medication doses or schedule without consulting your doctor.

If you’re taking an oral steroid medication, don’t stop it suddenly as it might lead to unpleasant withdrawal symptoms. If your asthma medications don’t seem to help with managing or preventing attacks, discuss this with your doctor. Your symptoms may not improve immediately after starting Xolair, but for the best results, continue receiving the injections as instructed. If there’s no improvement after a few weeks, have a talk with your doctor.

For the best benefit, use Xolair regularly and make sure you get your prescription refilled before you completely run out.

Precautions:

You shouldn’t use this medication if you’re allergic to omalizumab or any inactive ingredients in Xolair. For a full list of ingredients, check the Xolair ingredients list.
