I have had headaches - but only minor ones and they went away with my normal headache meds. This ended for me after about 12 days. I am sure it is different for everyone! Hope this helps!

i have been on phentermine a month now and the only time i really get headaches is if i go a long time not eating. I do not know exactly how it is working for you but sometimes if I am not hungry and no I need to eat something I will have a banana or a south beach diet meal mar with has lots of protein and nutrients and I am getting what i need to hold me off until a meal but technically I am not eating that much by my eyes!! Hope I was helpful:)

It could be the increase in blood pressure, which is a side effect of the meds.

I've been taking the drug for about 3 months. Yes, I've had terrible headaches also! They can happen for a number of reasons. More commonly, if you aren't getting enough fluids, or nutrition. You could be mildly dehydrated as well. If you are urinating a lot, the loss of potassium is another reason for the headaches (again, related to dehydration by urinating a lot). Try eating a banana and drinking plenty of water, if meds don't help your headaches. That seemed to help me more than meds.

I normally eat a small breakfast in the morning either before or after i take my half of pill because i went from 30mg to 37.5 cause i wanted to split my pills in half. also i try to snack on something every two to three hours throughout the day even if i'm not hungry. I also drink plenty of water to put in all lost fluids from exercising and urinating. Try this to see if it stop your headaches if not it could be an increase in your blood pressure. If your not checking it when your headaches occur I would suggest you do so quick.
