Let's take a minute to talk about your medication. This is Pulmicort Flexhaler. It helps control asthma so you have fewer flare ups. This medicine reduces swelling in the lungs to help keep your airways open. It is important to know Pulmicort is not a 'rescue inhaler.' It cannot treat sudden breathing problems.  Pulmicort Flexhaler is inhaled through the mouth and into the lungs. Your doctor will determine what dose is right for you. After your dose, rinse your mouth with water, and then spit the water out. This reduces your chance of getting an infection in your throat called 'thrush'. You should use the inhaler exactly as your doctor tells you to and read the 'Instructions for Use' for full information. If you still have questions, your doctor or pharmacist can help. Most people tolerate this medicine well. Common side effects include a sore throat, stuffy or runny nose, and nausea. It could also cause an upset stomach, diarrhea or loss of appetite. These effects are normal if they are mild and should go away. But, if these or other side effects become reasons you want to stop taking it, please talk with your doctor or pharmacist. As with any medicine, rare but serious side effects can occur. You should read the Patient Information Sheet to know which symptoms to watch for and when to report changes. You should call your doctor right away if you ever feel your breathing is worse, or if you notice any unusual changes to your body. Pulmicort Flexhaler may interact with other medicines. You should check with your doctor or pharmacist before taking any new medicines. Women should talk to their doctors before becoming pregnant or breastfeeding. For best results, use Pulmicort Flexhaler exactly as prescribed, and follow your doctor's recommendations for lifestyle changes that may help you breathe easier.
