Hi guys, my HA has been doing well, flying under the radar for the most part due to treatment. I started doxycycline a couple weeks ago due to moderate acne I’ve had for years and haven’t had success with treatment with other things. The first week I took it, it was fine. But since around last Friday, I’ve had dizziness, feeling woozy, and a terrible headache. My resting heart rate has also increased. I’m wondering if this is due to the doxycycline. It’s a pretty big dose, at 200mg per day. It’s clearing up my face really nicely though. Has anyone ever taken this and had these kinds of effects. Thanks!
