Let's take a minute to talk about your medication. 

This is Nucala. It helps control asthma and may reduce severe attacks. It also helps treat a condition known as EPGA, which affects blood vessels. Nucala may have other uses, too.

Nucala is an injection given under the skin once every 4 weeks. Your dose will be given to you by a healthcare professional. You should read the 'Instructions for Use' for full information. But, if you still have questions, your doctor or pharmacist can help.

Most people tolerate this medicine well. Common side effects include headache, back pain, and feeling a little weak or tired. You can also have mild pain, itching or redness at the injection site. These effects are normal if they are mild and should go away. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. You should not stop taking this medicine unless your doctor says it's okay.   

As with any medicine, rare but serious side effects could occur. With Nucala, these include a severe allergic reaction, or infections like shingles. You should read the patient information sheet to know which symptoms to watch for, and when to report them. To help keep this medicine safe for you, your doctor will follow your condition closely. Your doctor will also monitor you after your dose is given. 

It is not known if this medication can harm unborn babies. So, women should check with their doctors before becoming pregnant and before breastfeeding.

For best results with Nucala, you should track your symptoms. Remember, always call your doctor right away if your breathing problems get worse, or if you need your rescue inhaler more often than normal.
