I know that I can't take doxy and mepron togetehr.

Are thre any othes of the above list that should not be taken together?

I looked at the Drug Interactions digest and they didn't come up with any interaction (even for the doxy/mepron).

Since I know doxy /mepron is not okay, I didn't really trust the info I got there.

Was hoping some you you all might have some info.

Doxycycline
Ketek
Mepron
Plaquenil

ALCOHOL may interact with DOXYCYCLINE

Doxycycline is broken down and removed from the body by the liver. If you are taking doxycycline and have been consuming alcohol on a regular basis for a long period of time, the drug may be broken down at a faster rate than normal. If this happens, then potentially less doxycycline would be available for the body to use and blood levels could become too low. This could make doxycycline less effective at treating an infection. On the other hand, alcohol may increase the absorption of doxycycline from the stomach. This is more likely to happen when alcohol has not been consumed on a regular basis. Although this may cause blood levels of doxycycline to be increased, it is not likely to increase the beneficial effects of the drug. You may want to ask your healthcare provider about this potential interaction if you think you are having problems.

This interaction is poorly documented and is considered minor in severity. http://www.drugdigest.org/DD/Interaction/ChooseDrugs/1,4109,,00.html
