• Birth Defects: Tracleer can cause birth defects if taken during pregnancy. It is contraindicated in pregnancy and requires strict contraception measures for females of childbearing potential.
• Fluid Retention: Some individuals may experience fluid retention or peripheral edema while taking Tracleer, which can lead to swelling in the extremities or other parts of the body.
• Anemia: Tracleer may cause a decrease in red blood cell count, leading to anemia. Regular monitoring of hemoglobin levels is necessary during treatment.
• Decreased Sperm Count: Tracleer can reduce sperm count in males, which may affect fertility. It is important for men taking Tracleer to use effective contraception if their partner is at risk of pregnancy.
• Drug Interactions: Tracleer can interact with other medications, potentially reducing their effectiveness or increasing the risk of adverse effects. It is essential to inform healthcare providers about all medications, supplements, and herbal remedies being taken.
• Potential for Fluid Overload: Tracleer may increase the risk of fluid overload in patients with heart failure or compromised cardiac function.

It is crucial for individuals prescribed Tracleer to discuss these risks with their healthcare provider and to undergo regular monitoring to manage any potential side effects effectively.
