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

This is Letairis.  It helps treat pulmonary arterial hypertension, which is high blood pressure in the arteries of your lungs. It can help improve the ability to exercise and delay worsening of the condition.

Letairis is usually taken once a day.  It is important to swallow the tablet whole. Do not split, crush or chew them. You can take your dose with or without food. 

Most people tolerate Letairis well, but some side effects can occur.  These effects include inflamed nasal passages, stuffy nose or flushing.  These are normal if they are mild and should go away.  Another possible side effect is swelling of the hands, legs, ankles and feet.  These could be a symptom of a more serious problem so you should report it to your doctor. If these or other side effects become reasons you want to stop taking this medication, please talk to your doctor or pharmacist. But, do not stop taking this medicine unless your doctor says it is okay.

As with any medicine, rare but serious side effects could occur. You should read the medication guide to know which symptoms to watch for and when to report changes. To help keep this medicine safe for you, your doctor will follow your condition closely and may order blood tests.

Letairis is not safe for unborn babies.  Women should have a pregnancy test before starting Letairis. Women must talk to their doctors about which birth control methods to use and for how long. Women should not breastfeed.

Letairis can interact with other medicines.  Talk to your doctor or pharmacist before taking any other medicines, even if they do not require a prescription.

For best results with Letairis, take it exactly as your doctor tells you to, and plan ahead for refills.
