Question: Chlamydia and Laxatives

 Tess - Sun Feb 06, 2005 11:48 pm

I am currently taking the antibiotic, Doxycycline for the treatment of Chlamydia. I also have had to take some laxatives the past couple of days. Will this affect the treatment that the antibiotics are supposed to perform?

If the laxatives are causing loose or watery motions, the amount of the antibiotic available for absorption into the blood stream will naturally be less that the required dose. This may affect the efficacy of the drug and success of treatment.

It should also be noted that Doxycycline may reduce the efficacy of oral contraceptives if you are on this class of drugs.
