I was given Doxycycline on Tuesday after having my wisdom teeth extracted as an infection preventative. I followed the directions carefully as I have always been very sensative to medications and wanted to be careful with this new one. Wednesday evening within minutes of taking the pill I was overcome with nausea. I began to vomit and with in an hour had severe chest/stomach pains just below my rib cage. The following morning I called the prescribing Dr. right away- The Dr. told me to stop taking the Doxycycline. It is now Saturday evening (3 full days later) and the horrible chest/stomach pain has not at all subsided. I have had a hard time functioning in this much pain and am eager for it to end, to say the least. On top of all of this I have also experienced bloating in my stomach and an intense amout of gas. (burping, etc.) I realize I have obviously had a bad reaction to this medication, some people do and some people don't- it's the case with any drug. My main concern now is WHEN will these side effects end? How could two days on this medication have caused 3 additional days worth of such terrible pain? Should I contact my general physician on Monday, and if so is there even anything that they can do? I have had drug reactions in the past, typically when one ends a medication one is also able to end the uncomfortable reactions of the medication. This is a nightmare....How long does this stuff stay in a person's system???? Scary thought, isn't it.
