I think you are referring to something called the Serotonin Syndrome, which is a rare but serious drug reaction that can cause, among many other things, wild fluctuations in blood pressure. This can occur when taking 2 different anti-depressants in fairly large doses, for example.
A mild elevation of BP from a previous norm as described in the post, is not likely to be serotonin syndrome, which is an emergency condition. BP can vary from day to day, and even hour to hour.
The meds the poster is taking are not likely to cause serotonin syndrome.
I think this forum is excellent for disseminating suggestions for alternative treatments, tricks for getting more comfortable, support and encouragement, etc. It is not the place for laymen to give medical advice, which is the job of professionals. I understand there is a lot of dissatisfaction with the standard treatment of PN, because the standard treatment frankly sucks. Nevertheless, fooling around with medicine can be counter productive, and even dangerous.
Readers should always consult with their providers when adding or stopping any drug.
No offence intended.
