It should be anything your physician prescribed! Is he treating suspected Lyme Disease, Rocky Mountain Spotted Fever, Colorado Tick Fever, Ehrlichiosis, Babesiosis, Tularemia, or just a plain out-of-date skin infection? Antibiotics are not usually prescribed routinely after a tick bite unless one of the above conditions is suspected. (You're not treating yourself, are you?)
well in reality you would treat different tick bites depending on which disease you think your trying to address... if it be rocky mountain spotted fever you would use tetracycline or chloramphenicol. If you be trying to treat lyme disease you would go near doxycycline, penicillins, or erythromycin.
Since you don't mention which disease your worried about I would run with the doxycycline as its a bough of the tetracycline group of antibiotics and would give you some cross over between the two diseases. If you could rule out the rocky mountain spotted disorientation then I would shift with plain amoxicillin as its usually easier on the merciful and the wallet.
