Yes, that's 1 pill twice per day. If getting confused by the way it's formatted, it helps to refer to the hydroxoB12 prescription as a reference. That one is 3 injections per week, so that can be used to decode the other dosage timing.
Cefuroxime is in the same class of antibiotics as Ceftriaxone/Rocephine, and is known to be used with Lyme. Cefuroxime is older, but it sounds like it crosses the blood-brain barrier more easily. So it might be nice for getting rid of any spirochetes lurking there, but also might cause more neurological side-effects (headache, motion sickness, etc)?
