Why does PT-141 cause nausea?

Nausea was a counted study result, not a rumor. The two RECONNECT studies, in 1,267 women who had not reached menopause, over 24 weeks, found nausea, flushing, and headache, each in 10% or more, on bremelanotide 1.75 milligrams taken as needed. It works by switching on melanocortin receptors in the brain. That is why its side effects differ from erection drugs, which work on blood flow. A 52-week follow-on in 684 women, where everyone knew they were getting the drug, gave longer safety data. This FAQ reports that counted rate. It does not turn it into a prediction for any one person.

Part of more absences and national fields. Further harvested questions after the first names-and-absences set: more side effects the citations did not count, compounding formulas this catalogue does not hold, national legal-status fields for compounds that only have those four countries, trial windows rather than an onset clock, and named prescription combinations with no interaction table.
