I've been having hot flashes since early January. I started tindamax mid December, started ceftin in late December, and continued taking the doxy and mepron that I've been on for a year or so. Anyhow, I've been having hot flashes all day and night. I turn on a desk fan 5-10 time per day. I thought this may be hormonal. However, yesterday I missed my ceftin morning dose and realized when I got home i didn't have any hot flashes or ones that required a desk fan, so I skipped my evening dose last night. Well I resumed taking it this morning and within 30 minutes, I'm flashing. I don't know if this is a herx or a reaction. I don't feel ill. I will continue, but I was wondering if anyone else has hot flashes from ceftin. Also, I keep feeling this pressure around my sinuses. It's a pressure that builds up and then passes, but some pressure remains. I took sinus congestion medicine and that didn't help. My MRI showed mild sinus inflammation. This has been happening for a couple of weeks. No headaches. Thanks for reading.
