Hi All - Has anyone ever had to use an EpiPen with a hyperpots diagnosis? Recently I've been having acute allergic reactions with throat involvement. Luckily they have resolved themselves with steroids and antihistamines but in the event that I would have to use my EpiPen I am worried about the effect that it would have on my blood pressure as my spikes take my systolic above 180. Thanks
