Getting headaches- start up SE of Topamax?

hi! Hoping for some guidance. Getting onto Topamax is a bit of a struggle!

I increased my dose to just 37.5 mg a week ago and have literally had a headache ever since. It’s a different type of headache to my norm. A real pressure in the back of my head and ache. It gets worse within 45 mins of taking the tablet but literally stays with me all day.

Has anyone had headache as a SE? Does it get better?

This is doing my head in because its making me feel worse and panadol won’t even help the pain. Got to keep working.

Thank you x
