there was a study published february 2022 that showed that acetaminophen also increases blood pressure. I was pretty aware that both pseudoephedrine and ephedrine raised blood pressure slightly - but it's always good to see it mentioned online where other people may not have known.
In my case, I was taking ibuprofen+pseudoephedrine, so acetaminophen wasn't a confounding factor.
And yes, there's plenty of literature showing a slight average increase in bp -- but it seems that there's a wide variance, with some people having dramatically larger side effects.
