Your doctor may prescribe a non-steroidal anti-inflammatory drug (NSAID) such as ibuprofen or naproxen to treat bone pain caused by Zarxio. Zarxio helps the body make more white blood cells by stimulating the immune system, which also creates histamines. So your doctor also may recommend an antihistamine such as Claritin (chemical name: loratadine) – NOT Claritin-D – to ease bone pain caused by Zarxio.
