Hi , and thanks for posting this question - it's a good one! While I am hopeful others in the community will see your inquiry and respond by sharing their own personal experiences with you, I also have something to add.
As you may be aware, medications can affect everyone differently. This applies to both their level of efficacy, as well as the untoward side effects that may be associated with them. Trelegy, naturally, is no exception.
Since you may feel like you are 'in the middle' between your allergist (who prescribed Trelegy), and your primary care physician (PCP), who is looking out for high blood pressure, you may want to ask them to collaborate with one another. Once they do, they can advise you more uniformly of how you should approach being on Trelegy at this time. This would be the best possible approach and take a lot of the burden off you, and keep the doctors cognizant of their responsibilities.
What do you think?
