Lyme Disease Treatment: Antibiotics, Timelines and Recovery

Quick answer

Lyme disease treatment is a course of antibiotics. Most people take doxycycline, amoxicillin or cefuroxime axetil by mouth for 10 days to 4 weeks, depending on their symptoms. Some heart, nerve or joint cases need IV antibiotics. People treated early usually recover rapidly and completely, according to CDC.

This page explains what the guidelines say so you can have an informed conversation with your provider. We never list doses. Your prescriber sets the dose based on your age, weight and health.

Antibiotics for Lyme disease

Three antibiotics taken by mouth are the mainstays of Lyme disease medication:

• Doxycycline. Usually listed first in CDC’s clinical tables. CDC lists it for adults and, for many forms of Lyme, for children of any age.
• Amoxicillin. A penicillin-family antibiotic and an option for children of all ages.
• Cefuroxime axetil. A cephalosporin used as another first-line option.

For people who cannot take any of these, CDC says azithromycin may be used, but it is less effective, so symptoms should be watched closely to make sure they clear.

When the infection is more serious, some people receive ceftriaxone through an IV, usually in a hospital or clinic at first. CDC notes many can switch to pills once they are stable.

Doxycycline for Lyme disease

Doxycycline is the antibiotic most people associate with Lyme. A few things to know:

• Children: The old rule against doxycycline under age 8 came from concerns about older tetracycline drugs staining teeth. The 2020 guideline says newer evidence casts doubt on that risk for doxycycline and supports short courses in young children. See Lyme disease in children.
• Pregnancy and breastfeeding: The guideline says the safety of doxycycline in pregnancy is uncertain, and its use while breastfeeding should be individualized. Talk with your provider about alternatives.
• Prevention after a bite: In certain situations, CDC says a single dose of doxycycline may lower the chance of Lyme: when it can be given within 72 hours of removing a blacklegged tick, in an area where Lyme is common. Ask your provider whether it fits your situation, and see our tick bite guide.

Treatment by type of Lyme disease

How long treatment lasts depends on what the infection is doing. CDC’s clinical guidance, which follows the IDSA/AAN/ACR guideline, lists these typical courses:

A few more points from the guidance:

• When studies show more than one length works, CDC prefers the shorter course, to reduce side effects such as diarrhea and the risk of antibiotic resistance.
• When Lyme affects the brain or spinal cord itself, the guideline prefers IV antibiotics over oral ones.
• Severe carditis needs immediate hospital care with heart monitoring. Some people need a temporary pacemaker.
• If arthritis improves but does not fully clear after the first course, a second oral course or watchful waiting may be considered.
• If joint swelling persists after two courses, CDC says more antibiotics have not been shown to help and suggests seeing a rheumatologist.

The Jarisch-Herxheimer reaction

Some people feel worse soon after starting antibiotics. This short-lived flare is called a Jarisch-Herxheimer reaction. A medical review in StatPearls (from the National Library of Medicine’s bookshelf) describes it this way:

• It begins within 24 hours of starting antibiotics, often within hours.
• Symptoms include fever, chills, headache, muscle aches and a faster heartbeat.
• It has been reported in roughly 7 to 30 percent of people treated for Lyme disease.
• It usually passes within 12 to 24 hours, and mild cases do not require stopping the antibiotic.

Do not stop your antibiotic on your own. Call your provider if you feel much worse. Hives, swelling of the lips or throat, or trouble breathing are not a Herxheimer reaction. They can signal an allergic reaction and need emergency care.

Recovery from Lyme disease

Most people start to feel better during treatment, and CDC says people treated early usually recover rapidly and completely. Recovery time varies with how far the infection had spread:

• Lyme carditis: CDC says patients generally recover within 1 to 6 weeks.
• Facial palsy: Facial movement usually returns gradually. In one US study, about 89 percent of treated patients recovered completely.
• Arthritis: Many people improve after one or two courses. People with lasting swelling may be referred to a rheumatologist.

Some people have fatigue, body aches or trouble thinking that last after treatment. CDC calls this post-treatment Lyme disease syndrome (PTLDS). Most people improve over time, though it can take months. Read our balanced guide to chronic Lyme disease and PTLDS.

Things that can help during recovery:

1. Take every dose and finish the full course, even if you feel better.
2. Keep a simple symptom diary so you and your provider can see progress.
3. Go to follow-up visits, especially after heart or nerve involvement.
4. Ask what to do if symptoms return or new ones appear.

Another view: ILADS

The mainstream position is different. The IDSA/AAN/ACR guideline strongly recommends against more antibiotics for fatigue, pain or thinking problems without objective signs of ongoing infection. NIH-funded placebo-controlled trials found that prolonged antibiotics did not work better than placebo for lingering symptoms and caused serious side effects in some participants. We explain both sides in more depth on our chronic Lyme disease page.

A word on unproven treatments

You may come across supplements, herbal protocols, and other treatments marketed online for Lyme disease. We have not found good-quality studies showing that these treat Lyme infection, and they are not part of CDC or IDSA/AAN/ACR treatment guidance. If you are considering any of them, talk it through with a provider you trust, and be cautious about anything that promises a cure or comes with a high price.
