Hi all I'm taking propanopol for anxiety low dose 20 mg a day. I've been getting a tension headache since starting this medication it's only been a few days. I'm hoping it's not related to the medication. I live in Chicago and there has been a huge change in weather it went from the 60s to 90s back down to the 80s so I'm wondering if my headache is weather related? I'm just so scared of taking beta-blockers and I'm hoping it's not going to lower my blood pressure as I already have normal blood pressure. The doctor said a low-dose shouldn't do that at all.
