Has anyone taking sotatercept (Winrevair) experienced gut issues like heartburn, reflux, GERD, cramping, or indigestion?
It's understandable to be concerned about how sotatercept might affect your existing gut issues, especially since you're already managing them alongside your current medications.
Sotatercept is a newer medication that works differently from your current treatments (Tadalafil and Opsumit). It targets the activin pathway rather than the nitric oxide or endothelin pathways. Because it's a first-in-class treatment, there's less long-term data available about all potential side effects compared to older PAH medications.
Your current medication, Opsumit (macitentan), is an endothelin receptor antagonist that can cause GI-related side effects including GERD, constipation, and diarrhea. This class of medications is known for causing gastrointestinal issues.
When considering sotatercept as an addition to your current regimen, it's important to discuss with your doctor:
* How sotatercept might interact with your existing gut issues
* What monitoring will be in place to track any new or worsening symptoms
* Whether adjustments to your current medications might help manage GI symptoms
Since you and your doctor have identified this as a potential next step, make sure to have an open conversation about your specific concerns regarding your gut health and what warning signs to watch for.
