Has anyone else had serious issues with Doxycycline Monohydrate 150mg Caps? I'm on my 3rd day of taking them for acne, and I've started to have some scary symptoms. I read the side effects, but it's a lot to take in. Has anyone else had Clostridioides difficile-associated diarrhea or other scaring side effects? What should I be on the lookout for? I'm really worried that I need to stop taking them, but my acne is so bad I don't want to stop treatment if it can be managed. I'm also getting a headache, but my vision seems okay. I don't know if this is related but I'd love to hear about it, if you've had the same thing happen!

I wish I had known about vision problems! I got them and it was scary. I thought I was going blind. It took a few days to go away after I quit taking them, but it was awful.

I had to go to the hospital, and my doctor had to change out my antibiotic entirely! Seemed a bit silly to me, but I guess they were worried about all these severe side effects.

I'm so glad you posted this! I've been worried because I have a few of the symptoms but not all of them. I definitely need to talk to my doctor about this. Also, I've had trouble swallowing water and I have no idea what that's about. I never knew it could cause that. Shame you didn't know about those side effects.

I wish I had thought to look this up sooner. I had some weird side effects, but nothing so bad that I had to stop taking them, and I'm wondering if they were related at all. I'm glad I have this info now, though!

I'm so sorry you're dealing with this! If you experience any more signs of an allergic reaction, like swelling of the face or severe stomach pain, then it's definitely time to call a doctor or go to the ER. I had to stop taking it due to Throat irritation, but I had no idea it could be that serious. I never knew this. I would have stopped taking it right away if I did!

Does anyone else find this medication useful? I feel like I've had a lot of side effects, but nothing that bad so far. I'm a little worried about the diarrhea, though. I had that before and it was awful.

I had to stop Doxycycline because of severe dizziness. It was terrifying. I felt like I was going to pass out every time I stood up. I had no idea this could happen with antibiotics. However, I think it was worth it. My acne is gone. Now I just have to deal with the fact that I can't be in direct sunlight without burning.

I had to stop taking Doxycycline due to chest pain. It was scary. I had to go to the ER and it took a while for them to figure out what was wrong. The doctors weren't even sure it was the medication at first. It was awful.

Your rash should have been prevented! I got the rash and had to stop the medication. It went away after that, but it was awful and lasted for a while. If I had known it could be so bad, I'd have quit taking them!
