I have just finished my fourth week of doxycycline and my Infectious Disease doctor is saying that he is open to continuing the antibiotics for another 4 weeks. My symptoms have dwindled and I have occasional tingling in my hands and feet and pressure in my head occasionally.

So my question is should all of my symptoms be completely gone before stopping the antibiotics? I am asking because I know that so many of you can speak from personal experience.

I have to make a decision today because my prescription runs out this evening.

You are still within the window where you can probably wipe this bugger out completely if you treat it long enough, so if comes down to either taking ABX for a little longer now, or a LOT longer later, which would you prefer?

Generally speaking, it's said that treatment should continue until all symptoms have been gone for about 2 months.

If you stop when you first seem to be over it, there could still be some spirochetes present. With time, they will multiply to the point that your LD will flare up again.
It it much more difficult to deal with then.

In my opinion, it's better to treat a little too long than to take a chance on not eradicating the disease when you have the opportunity.

Better to err on the side of caution.

What dose of Doxy are you taking per day?
