Bosentan (Tracleer) improves your ability to exercise and slows worsening of pulmonary arterial hypertension (PAH), but it has several drug interactions and can cause liver damage.
Pulmonary arterial hypertension (PAH)
Bosentan (Tracleer) is an endothelin receptor antagonist. It works on proteins in your body that control the blood flow going to your lungs. This medication relaxes the arteries in your lung and allows more blood to flow through. As a result, your heart is able to pump better, your body gets more oxygen, and you should be able to breathe and exercise easier.

Bosentan (Tracleer) interacts with quite a few medications. Some of these interactions can be serious or life-threatening. Make sure your provider and pharmacist are aware of all the medications that you are currently taking, including over-the-counter products, vitamins, and herbal supplements.

Risk factors: Current liver problems | People taking high doses of bosentan (Tracleer)
Rarely, bosentan (Tracleer) can cause severe liver damage, including liver failure. This is one of reasons why you, your provider, and your pharmacy are required to sign up with the Risk Evaluation and Mitigation Strategies (REMS) program for this medication. You'll need to get liver blood tests every month, since it is usually hard to tell if there is damage early on. Liver damage is more likely to happen if you already have liver problems or are taking more than 125 mg of bosentan (Tracleer) twice a day. Do not take more medication than what your provider prescribed for you. Never take extra or double up in order to make up for a missed dose. If you notice severe nausea, vomiting, right-sided stomach pain, fatigue, low or no appetite, or yellowing of the skin or eyes, seek medical help right away.
Bosentan (Tracleer) can cause serious birth defects, which is why all female patients, their provider, and their pharmacy are required to sign up with the Risk Evaluation and Mitigation Strategies (REMS) program for this medication. If you're a female and haven't gone through menopause yet, you will be required to use 2 types of approved birth control while taking bosentan (Tracleer) and for one month after stopping the medication. You will need to provide a negative pregnancy test every month before you can get a medication refill. Tell your provider right away if you think you're pregnant or if you are unable to use your prescribed birth control.
Risk factors: Heart failure
Bosentan (Tracleer) can cause fluid build-up, especially if you have a history of heart failure. If you have any heart problems, let your provider know before starting bosentan (Tracleer). Contact your provider immediately if you notice unusual swelling in your arms or legs, rapid weight gain (more than 3 pounds in a day or 5 pounds in a week), or trouble breathing.
Although rare, bosentan (Tracleer) can cause a serious type of lung condition called pulmonary veno-occlusive disease, which can cause fluid build-up in the lungs. If your PAH symptoms get worse, breathing becomes difficult when you lie down, or if you develop a cough that doesn't go away, seek medical help right away.
Bosentan (Tracleer) can cause problems with sperm production. This can affect your ability to have children. If you are a male and would like to have children in the future, let your provider know before starting bosentan (Tracleer).
Risk factors: Low hemoglobin (anemia)
Bosentan (Tracleer) might cause your hemoglobin levels to go down. Hemoglobin is the protein on your red blood cells that carries oxygen. You will need regular blood tests while taking this medication to make sure your hemoglobin stays at a healthy level. If you experience difficulty breathing, lightheadedness, or more fatigue, let your provider know.
Adults and children over 12 years old: Start with 62.5 mg by mouth twice daily. After 4 weeks, if you weigh over 40 kg (88 pounds), your provider might increase your dose to 125 mg by mouth twice daily.
Children ages 3 to 12 years old: Depending on your child's weight, they can take between 16 mg and 64 mg by mouth twice daily.
