Effectiveness of Antibtiotics

[Guest guest]

I've been taking doxycycline for 2.5 yrs. I used to take it every

day and it helped a lot. Since I started to taper off, I've noticed

the skin not looking as good. However, I'm afraid to take it daily

(or too often) because I hear its effectiveness diminishes if you're

on it for a long time. I read somewhere that after 8 yrs it's common

for the drug to lose its effectiveness.

1. So if I take doxycycline less frequently, will I be able to extend

the life span of its effectiveness?

2. Also, the way I'm taking the antibiotics is this: when the skin

starts looking bad, I take it for 3 days straight. Then when the

skin stabilizes, I take the doxy less frequently (like maybe 1-

2x/week). Is this fluctuation bad for my system?

3. When the time comes that I find doxycycline has lost its

effectiveness, would I be able to find benefit from switching to

tetracycline or minocycline?

Thanks.
