Every person has around 600 lymph nodes, according to the National Institutes of Health. These groups of nodes act like tiny Brita filters, storing white blood cells and eliminating potentially harmful foreign substances. When these nodes swell up, it\u2019s a natural immune system response to illness. It shows that they\u2019re working to clear infections from the body.\u00a0<\/span><\/p>\n

Typically, treating swollen lymph nodes (lymphadenopathy) means treating the underlying cause. Antibiotics can help, but it depends entirely on the type of illness that\u2019s causing the swelling. Here\u2019s all the important information.\u00a0<\/span><\/p>\n

Do antibiotics help with swollen lymph nodes?<\/span><\/h2>\n

They can, but only in certain cases.\u00a0<\/span><\/p>\n

The most common <\/span>cause of lymph node swelling<\/span><\/a> is infection\u2014often an upper respiratory infection, the common cold, influenza, sinus infections, strep throat, tonsillitis, or infectious mononucleosis. Sometimes the lymph nodes themselves can become infected (lymphadenitis).<\/span><\/p>\n

Along with symptoms like sore throat, runny nose, or fever, these infections may cause the lymph nodes on the side of the neck, jaw, and chin to become enlarged, tender, or painful to the touch. Illnesses can sometimes cause lymph node inflammation in another part of the body\u2014like the armpit, ear, leg, or groin areas\u2014but the swelling is often close to the site of an infection.\u00a0<\/span><\/p>\n

When the infection is bacterial, antibiotics can help. \u201cA partial treatment that incorporates the use of antibiotics is suitable only if its cause is a bacterial infection, such as streptococcal pharyngitis (strep throat) or bacterial lymphadenitis,\u201d says Dr. Michael Chichak, MD, medical director at MEDvidi. \u201cAntibiotics will never be useful if a viral infection, like the ones caused by common colds or mononucleosis, is the underlying cause.\u201d<\/span><\/p>\n

Per Dr. Edmond Hakimi, DO, medical director at Wellbridge, \u201cif it is something viral\u2014like a cold or the flu\u2014antibiotics will not help because they only work against bacterial infections, not viruses. In those cases, your lymph nodes typically go down on their own once your immune system clears things up.\u201d<\/span><\/p>\n

These drugs stop the bacteria from spreading by attacking their cell walls or inhibiting their ability to multiply, per the<\/span> Nature Reviews Microbiology<\/span><\/i>. So if the healthcare provider suspects strep throat, tuberculosis, cat-scratch fever, skin infections, or other bacterial health conditions, they may prescribe an antibiotic. People whose enlarged lymph nodes come from a virus like a cold or flu, however, will see more success with antiviral medications or getting rest while the infection runs its course.\u00a0<\/span><\/p>\n

Rarer possible causes of swollen lymph glands include injuries, certain medications, human immunodeficiency virus, autoimmune disorders like rheumatoid arthritis, or cancer (like leukemia). The healthcare provider will develop a treatment plan specifically to suit the cause.\u00a0<\/span><\/p>\n

What are the best antibiotics for swollen lymph nodes?<\/span><\/h2>\n

When lymphadenopathy comes from a bacterial infection, antibiotic therapy is <\/span>one of the most common treatment options<\/span><\/a>. The particular antibiotic that works best depends on the type of infection, the patient\u2019s medical history, and other medications they\u2019re taking.<\/span><\/p>\n

That said, some of the most <\/span>commonly prescribed antibiotics<\/span><\/a> for bacterial infections include:<\/span><\/b><\/p>\n
