Lyme disease is an inflammatory condition caused by the bacterium Borrelia burgdorferi, typically transmitted through the bite of infected deer ticks. This disease is characterized by a distinctive rash known as erythema migrans, joint inflammation, and flu-like symptoms. If left untreated, Lyme disease can progress, potentially affecting the nervous system, heart, and joints, leading to chronic symptoms such as arthritis, carditis, or neurological issues.

Early treatment is crucial to prevent progression, and antibiotics are the primary treatment for Lyme disease. A variety of antibiotics may be used, and the choice depends on factors such as disease stage, patient age, and presence of any co-existing health issues. Common antibiotics include:

• Doxycycline is a commonly used antibiotic for the treatment of Lyme disease, especially in adults and children over the age of 8. It is known for its effectiveness in combating Borrelia burgdorferi, the bacterium responsible for Lyme disease, and is typically a first-line treatment option. However, doxycycline carries a Category D pregnancy risk, making it unsuitable for young children under 8 years and pregnant women due to potential harm to fetal development.

Dosage for Doxycycline

• Adults and children over 8 years: 100 mg taken twice daily for a duration of 10–21 days.
• Not recommended for children under 8 years or pregnant women.

The exact dosage and treatment duration should be determined by a healthcare provider based on the patient’s symptoms and the stage of Lyme disease. Completing the entire prescribed course of doxycycline is essential to avoid complications and ensure effective treatment.
