[Question #2313] Doxycycline Effectiveness

44 months ago
HI, I was concerned about the effects of alcohol on doxycycline. I've read its okay to consume 1 to 2 drinks per day if on doxycycline. Although pharmacists have told me that drinking or binge drinking can reduce it's effectiveness. I had a total of 3 drinks during my 7 day course of doxycycline of which I spaced the doses at equal times, although once it was take about 12-14 hrs later rather than 12 hrs. After my final dose, 12 hours later I had 2 beers. I also had 2 yogurts during the course, and was concerned about the calcium. Also, I was consuming daily cloves of garlic to help.

This is your 3rd new question in 8 days and you are repeating yourself.  I answered your questions about alcohol use, as well as yogurt a week ago.  Repeating the question will not change the answers.  While many people including health care providers and, apparently pharmacists still tell people that ingestion of alcohol can impair the effectiveness of doxycycline that is a myth, particularly in instances in which alcohol ingestion is modest as is the case for you. 

Milk and milk products eaten an hour before or two hours after taking doxycycline can impair absorption and therefore the effectiveness of the medication but in your case. two yogurts should not negatively outcome your chlamydial treatment.   

Dr. Handsfield warned you about further posts.  I answered this question but will not reply to follow-ups and further repetitive, anxiety-driven questions will be deleted.  Prove to yourself that you have been cured by having a repeat chlamydia test about three weeks after completion of therapy but please understand the further posts on this topic will be deleted without comment.  EWH
