Most doctors 'think' that 14 days worth of Doxycycline will kill off the Lyme Borreliosis and that you're healed. This may be the case if you are bitten, rip the tick off and high tail it to your doctor asap! Nothing could be further from the truth if you have had untreated Lyme for weeks, months or years.
(Please note that not all co-infections can be erradicated with antibiotics, some require antimalarial drugs etc.)
Common Antibiotics Used in the Treatment of Lyme Borrelia (borreliosis)
Doxycycline. This antibiotic is effective against both Lyme disease and human granulocytic anaplasmosis (HGA) and so is the standard antibiotic for any patient over 8 years old (except pregnant women). Doxycycline cannot be used routinely in children under 8 years old. It is a form of tetracycline and as such discolors teeth and inhibits bone growth. It can also cause birth defects, so it should not be used during pregnancy.
Either amoxicillin (one of the penicillins) or cefuroxime (Ceftin) -- a drug known as a cephalosporin -- are the alternative treatments for young children and some adults. Amoxicillin is the first choice and also probably the best antibiotic for pregnant women. Unfortunately, many people are allergic to penicillin. In addition, strains of bacteria are emerging that are resistant to penicillins.
Intravenous ceftriaxone -- another cephalosporin -- may be warranted if there are signs of infection in the central nervous system (the brain or spinal region) or heart.
Other types of antibiotics, such as macrolides, are not normally used for first-line therapy.
