Selexipag may be used along with Pulmokit, which contains Ambrisentan and Tadalafil, in some patients with pulmonary arterial hypertension as part of combination or triple therapy, but this is strictly not for self use and must only be decided by a specialist because the treatment is highly individualised based on factors like disease severity, blood pressure, heart function, oxygen levels, response to current therapy, and side effect risk; using these medicines together can increase the chance of side effects such as low blood pressure, dizziness, headache, flushing, and fluid retention, so careful monitoring and dose adjustment under a cardiologist or pulmonologist is essential.
