Lyme Disease

By: Dr. Chelsea Slyker, PharmD, MPH


Lyme disease is a tick borne illness that is estimated to affect around 300,000 people annually. It is carried by the black-legged tick, found in northeastern, mid-Atlantic, and north-central states, and the western black-legged tick, found on the Pacific coast. Most of those infected are bitten by immature ticks which are very small and hard to see. Lyme disease can be difficult to diagnose, so it is crucial to check for tick bites after spending time outdoors and be aware of the signs and symptoms.

Treating Lyme Disease

By understanding the early signs of Lyme disease, you can effectively treat it to prevent the potentially dangerous late symptoms. If you experience any early signs following a tick bite you should see a doctor right away for antibiotics. Lyme disease is typically treated with doxycycline, cefuroxime, or amoxicillin for a duration of 10-21 days depending on the patient. If these are used early, patients typically have a fast and full recovery.


This disease is seen more often in northeastern states, though cases have been reported across the nation. You should familiarize yourself with the symptoms regardless of where you live to prevent any long-term complications. Prevention is always the best treatment, so be sure to take the appropriate precautions when spending time outdoors.
