Let's take a minute to talk about your medication. This is Entyvio. This medicine treats severe cases of either Crohn's disease or Ulcerative Colitis. It may be able to get your condition under control, and help improve some symptoms. This medicine is given through a needle into a vein, usually in your arm. This is known as an 'IV infusion'. The dose takes about 30 minutes. Your nurse will watch you closely during the dose, and will treat any reactions that may occur. Also, he or she will teach you what reactions you should watch for a few hours after each dose. After the first dose, your doctor may prescribe another dose in 2 weeks, then 6 weeks, and then every 8 weeks thereafter. There are many common side effects. They include a headache, nausea, tiredness, bronchitis, rash, or itching. They also include pain in the back, throat, joints or extremities. You should call your doctor for medical advice about side effects. As with any medicine, more serious side effects could occur. With Entyvio, these include allergic reactions or liver problems. It's important to read the Medication Guide for full information. Entyvio may lower your ability to fight infections. You should tell your doctor right away if you have a fever, a cough, or any possible infection. This includes the common cold, the flu, and infections of the throat, nose, or sinuses. Be sure to check with your doctor or pharmacist before taking other medicines, and before getting vaccines. Also, women should check with their doctors before becoming pregnant or breastfeeding. For best results with Entyvio, ask about support services for patients that are available.
