Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: Any biologic medication such as mepolizumab can cause severe allergic reactions. If you experience itching, rash, dizziness or fainting, difficulty breathing or swelling of the throat or tongue, seek medical help immediately. These reactions usually occur soon after receiving a dose of the medication, but sometimes occur days after the dose and can occur at any time during your treatment with this medication.
Asthma symptoms: This medication is not intended for use during an asthma attack. Use your reliever medications when you have an episode of wheezing or difficulty breathing.
If your asthma worsens after you start using this medication, let your doctor know.
Other medications: Mepolizumab is not intended to replace other asthma medications. Continue to use your “preventers” (long-acting bronchodilators and corticosteroids) and “relievers” (fast-acting bronchodilators) as prescribed by your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication or less than 4 months after stopping this medication, contact your doctor immediately.
Breast-feeding: It is not known if mepolizumab passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under the age of 18 years.
