I was prescribed doxycycline 2xday for seven days. On the third day I started to feel very sick. However, it was not until the 5th/6th day that I began to suspect I was having a reaction to the antibiotic. I have never had a negative reaction to any medication ever. My symptoms started with severe nausea that lasted all day, and extreme tiredness. The symptoms continued to get worse....muscle aches, joint pains, elevated blood pressure, back & neck pains, unfocused vision, confusion, dizziness, loss of appetite, muscle tremors that woke me from sleep, depression, and anxiety. When I discussed with my doctor that I suspected it might be the medication I was dismissed and told I was developing a virus. They had prescribed this medication often with no problems. I decided to try to stick with it for two more days. That was the biggest mistake ever. I can't really describe what it did to my head, but all I could think about was that I was dying. I guess severe anxiety and paranoia. So, I finally stopped taking it. It took three full days with no medication for my nausea and mental confusion to begin to subside. It took a few more days for most of the muscle and back pain to go away. It also took about seven days for the depression and most of the anxiety to quiet down. It is now 11 days with no medication and I still have diarrhea, and minor joint pain. I have also stopped drinking coffee because I an still a bit anxious. I have not really gotten back to my routine yet, and will probably hold off going to the gym until next week. The most frustrating thing of all is that this medication was given to me as a preventative before a small surgery. All the symptoms I was supposed to be watching for I was having. I am sure this contributed to the anxiety. At least most of the symptoms have gotten better, and I am hopeful that they will continue to improve. I have researched serum sickness and it says it can take 1-2 weeks for symptoms to subside, and up to several months in some cases. Good luck to everyone.
