With summer here—and more time being spent outdoors—many individuals are concerned about sunburn, allergies, and first aid. However, one of the most significant and often-overlooked dangers is Lyme disease, which is the most commonly transmitted tick-borne infection in the United States.1 Because small ticks can be a significant threat, it is essential to be familiar with both preventative measures and symptoms.
Because our understanding of Lyme disease has advanced, we now know that the illness is caused by a spirochete bacteria known as Borrelia burgdorferi.2 This bacterium is transmitted via the bite of infected black-legged ticks, also known as deer ticks.1,3 Ticks are most commonly found in wooded areas but can also be found in lawns and shrubs.
Community pharmacists play a key role in helping patients identify signs of potential exposure, allowing for timely intervention and treatment.
SIGNS AND SYMPTOMS
The most common sign of Lyme disease is a bull’s-eye rash called erythema migrans, which is found in 70% to 80% of cases. The rash usually appears at the site of the tick bite approximately 1 to 2 weeks after the initial bite and can expand gradually over a few days, reaching up to 12 inches. The rash may feel warm to the touch and is normally not itchy or painful.1
Other early signs and symptoms seen between 3 and 30 days after a tick bite may include fever, chills, headache, fatigue, muscle/joint aches, and swollen lymph nodes. Later signs and symptoms, occurring days to months after a tick bite, may include severe headaches and neck stiffness, multiple bull’s-eye rashes on the body, facial palsy, arthritis with severe joint pain, and intermittent pain in tendons, muscles, joints, and bones. Lyme disease can have long-term effects affecting multiple vital organs, including the brain and nervous system, muscles and joints, heart and circulation, and digestion. Untreated Lyme disease can produce a wide range of severe symptoms including high fevers, facial paralysis, irregular heartbeat, and refractory arthritis.1

TREATMENT FOR LYME DISEASE
Treatment and duration may vary depending on the stage of Lyme disease, making it crucial for pharmacists to provide guidance to patients about the regimen selected. An analysis of the signs, symptoms, and blood tests will help determine the stage and treatment regimen accordingly. Stage 1 is called early localized Lyme disease, and in this stage, the bacteria have not yet spread throughout the body. Stage 2 is called early disseminated Lyme disease, which means the bacteria have now begun to spread throughout the body. Stage 3 is called late disseminated Lyme disease, meaning the bacteria have spread to distant sites such as the joints and nerves.1
A 10- to 14-day course of antibiotics is used to treat individuals diagnosed with early Lyme disease, and the duration of treatment depends on the medication selected. Common choices of antibiotics include doxycycline, amoxicillin, cefuroxime, and azithromycin. Later stages of Lyme disease are often treated with the same oral antibiotics for a longer period, usually up to 30 days. Intravenous ceftriaxone is sometimes utilized for refractory arthritis or neurologic disease caused by Lyme disease.4,5
In all scenarios, treatment should be initiated quickly and early for the best prognosis.
PREVENTION IS KEY
When it comes to ticks and Lyme disease, prevention is always the most effective strategy. Pharmacists should advise any patient engaging in outdoor activities, such as hiking, hunting, or walking, that preventing Lyme disease involves a combination of personal precautions and environmental management to minimize exposure to tick bites.
Patients spending time in wooded or grassy areas should wear long sleeves and long pants and tuck pants into socks to create a physical barrier against ticks.6,7 Remind patients who may be involved in outdoor activities to use insect repellents containing N,N-diethyl-m-toluamide (commonly called DEET) on the skin and permethrin on clothing for added protection.8
