Hello jennybjones. I couldn't find anything to say, yes, Phentermine causes headaches or migraines. I've followed this drug for some time now and people rarely report about headaches. I'd wait a bit and if they continues, don't ease up, I suggest mention it to your doctor. Get her/his thoughts to your question. Good wishes and health to you,pledge
