I don't know that Butran, or pain meds, do
necessarily cause dehydration. Some people get opioid-induced edema, which is retention of water. Dehydration or dry mouth (and headache) do come up as known side effects of many pain medications (including Butran), but the frequencies I've seen have been in the 5-10% range. Opioid pain medications do cause constipation, but from partial paralysis of the stomach, decreasing peristalsis, reducing digestive secretions, etc. Dehydration could certainly cause constipation, and drinking more water is advised to patients with opioid-induced constipation, but constipation doesn't necessarily mean dehydration.

Headaches from opioids
usually fade within a few days as the body adjusts to the medication.
Palpitations are also a known side effect, but could also be more serious; I'd call your doctor about that.
Dehydration will cause a headache - that's pretty much what a hangover is.
