Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
Have taken 4 doxycycline by late doses of 100mg for a respiratory infection ;upper stomach pain , & bad headache. Have taken doxy mono hydrate before , didn t experience this upper stomach pain. Last dose was taken around 10am, but did not take the evening one, how long before this gets out of my system.
The half life of Doxycycline is 18 hours. The half life of a medicine is the time it takes for the amount of drug in the body to decrease by half. It takes approximately 3 to 5 half lives for a medicine to be mostly eliminated.
This means that your medicine should be eliminated in approximately 2 1/2 to 4 days. You should let your doctor know about your reaction.
Hope I have answered your query. Let me know if I can assist you further.
Regards, Dr. Michelle Gibson James
