When the hollow cavities in the skull known as the sinuses become inflamed and congested, you have a case of sinusitis on your hands, or in your head, more specifically. Symptoms often include facial pain, nasal congestion, thick, colored nasal discharge, headache, bad breath, fatigue, fever, and even tooth pain. Not every case of <\/span>sinusitis<\/span><\/a> should be treated with an antibiotic. While bacteria can cause inflammation and congestion in the sinuses, viruses are the most common cause of sinusitis, according to the Asthma and Allergy Foundation of America (AAFA). That makes it unnecessary to use antibiotics since they are only effective against bacterial infections.<\/span><\/p>\n

However, sometimes mucus can build up in the blocked sinuses, leading to a secondary bacterial infection. That\u2019s when an antibiotic may be needed. According to the AAFA, if the sinuses remain blocked for a long time, such as 10 days or more, a bacterial infection is more likely to develop. In that case, <\/span>Augmentin<\/span><\/a> could be just the ticket. Augmentin combines <\/span>amoxicillin<\/span><\/a> (a penicillin) with clavulanate potassium (a beta-lactamase inhibitor). Some suggest that it may be more effective than amoxicillin in treating antibiotic-resistant infections.\u00a0<\/span><\/p>\n\t\t

Is Augmentin good for sinus infections?<\/span><\/h2>\n

\u201cThis is actually a first-line medication, meaning often the first medicine of choice, when treating acute sinus infections,\u201d says <\/span>Uma Darji<\/span><\/a>, MD, a family medicine provider in North Carolina. Augmentin is commonly used to treat respiratory tract, ear, and urinary tract infections.<\/span><\/p>\n

Before prescribing Augmentin or any antibiotic, your healthcare provider will likely perform an exam and ask you about your symptoms, including the duration and severity of symptoms. Many sinus infections clear up on their own if you give them some time.\u00a0<\/span><\/p>\n

\u201cI typically treat when symptoms last longer than 10 days, or if symptoms worsen significantly after at least five days,\u201d says <\/span>Lori Solomon<\/span><\/a>, MD, MPH, chair and associate professor of family and community medicine at New York Medical College.<\/span><\/p>\n

Although more <\/span>advanced diagnostic methods<\/span><\/a> aren\u2019t typically used to diagnose simple causes of acute sinusitis, in more serious cases, providers may obtain imaging of the sinus and nasal areas, perform a nasal endoscopy, or send nasal or sinus samples to the lab for analysis.\u00a0<\/span><\/p>\n

How fast does Augmentin work for a sinus infection? <\/span>\u00a0<\/span><\/i><\/h2>\n

The question on most people\u2019s minds when they start taking medication for a painful or annoying sinus infection is, \u201cWhen will I feel better?\u201d<\/span><\/p>\n

\u201cThat is variable, but most patients are better in seven days,\u201d Dr. Solomon says.\u00a0<\/span><\/p>\n

The medication actually starts working even sooner than that, as soon as an hour after the first dose. \u201cHowever, the patient will probably not notice a change in symptoms until three to five days later,\u201d says <\/span>Brian Laird, Pharm.D., MBA<\/span><\/a>, pharmacy operations manager at OSF Healthcare in Urbana, Illinois. \u201cSymptoms of a bacterial sinus infection are a combination of the bacteria\u2019s effect on the person and the body\u2019s immune system response to the bacteria.\u201d<\/span><\/p>\n

For that reason, you might also consider some other strategies to help you cope with the symptoms, such as irrigating or rinsing your sinuses with a saline solution, taking an over-the-counter pain reliever like <\/span>acetaminophen<\/span><\/a> or <\/span>ibuprofen<\/span><\/a>, or possibly using a decongestant.\u00a0<\/span><\/p>\n

Augmentin vs. amoxicillin for sinus infection<\/span><\/h2>\n

Your healthcare provider may still choose to prescribe <\/span>amoxicillin for a sinus infection<\/span><\/a>. \u201cAmoxicillin is reasonable for people with mild disease,\u201d Dr. Solomon says.\u00a0<\/span><\/p>\n

\u201cAmoxicillin with clavulanate is more effective and generally used in more severe cases and in people who have conditions like diabetes, kidney disease, heart problems, or immunocompromised conditions,\u201d adds Dr. Solomon. Clavulanate is like a \u201cbooster\u201d to amoxicillin, notes Dr. Darji.<\/span><\/p>\n

This ability to fight off infections caused by beta-lactamase-producing bacteria (such as Haemophilus influenzae and Moraxella catarrhalis, which can cause sinusitis) makes <\/span>Augmentin preferable to amoxicillin<\/span><\/a> for treating some bacterial infections. \u201cClavulanate, while not an antibiotic itself, helps treat infections caused by bacteria resistant to amoxicillin,\u201d Dr. Laird agrees. \u201cClavulanate blocks an enzyme bacteria use to break down amoxicillin. Without that enzyme, the bacteria are now susceptible to amoxicillin.\u201d<\/span><\/p>\n
