What If You Don’t Start To Feel Better
Most studies, such as the guidelines to treat ear infections in children, recommend that if no clinical improvement is seen within 48-72 hours of starting amoxicillin, therapy should be reevaluated.
Similarly, the American Academy of Pediatrics guidelines for the treatment of sinusitis states the following:
“Amoxicillin with or without clavulanate is the firstline treatment of acute bacterial sinusitis. Clinicians should reassess initial management if there is either a caregiver report of worsening or failure to improve within 72 hours of initial management.”
So overall, amoxicillin is absorbed quickly after taking a dose by mouth, and you should feel improvement in your symptoms within 72 hours. If you do not, it is important to speak with your doctor as your infection may be resistant to the antibiotic, and alternative therapy options should be considered.
Alternative therapies include:
Is Your Sinus Infection Acute Or Chronic
A short-term sinus infection is often referred to as acute sinusitis. Most cases of acute sinusitis last about a week, but this type of short-term sinus infection can last up to four weeks. If you suffer from a sinus infection that lasts longer than 12 weeks despite treatment from your doctor, its considered chronic sinusitis.
Drinking Liquids Help Ease Sinus Pain And Loosens Congestion
Staying hydrated keeps your sinuses moist so you feel better, and it also decreases the thickness of sinus mucus so it flows out more easily, Del Signore says.
Everyone is guilty of not drinking enough water, he says, recommending people get from six to eight 8-ounces glasses every day.
Steer clear of too many caffeinated or alcoholic drinks, which can cause dehydration.

Antibiotics And Sinus Infections
When a sinus infection hits, it seems worse than what you remembered from the last time you had one. This may give you the idea that you need antibiotics, but most clear up without them. Antibiotics have no effect on viruses and aren’t recommended within the first week of developing a cold. About 70% of sinus infections go away within two weeks without antibiotics.
Consider these other forms of treatments instead of antibiotics:
- These medications are available for over-the-counter purchase. Be careful to only take these medications for a few days at most, as they can cause the return of more severe congestions.
- Over-the-counter pain relievers Aspirins, acetaminophen or ibuprofen can help relieve temporary pain.
- Saline nasal spray This is used to spray into your nose several times a day to rinse your nasal passages. It can help to prevent and treat inflammation.
Antibiotics only will be needed if the infection is severe, recurrent or persistent.
The likelihood of bacterial infection increases when:
- Symptoms last seven days or more, particularly when symptoms initially improve and then worsen.
- Mucus is thick and yellow or green in color.
- There is facial or sinus tenderness, particularly if it’s worse on one side of the face.
- Pain is present in the upper teeth and is worse on one side of the face.
If the infection becomes severe, recurrent or persistent, contact your provider.
Amoxicillin Dosage For Pets
Both amoxicillin and amoxicillin-clavulanate are widely used to treat susceptible bacterial infections in domestic animals. Amoxicillin can be given as an oral tablet, and it is sometimes administered as an intramuscular, intravenous, or subcutaneous injection by a veterinarian, depending on the infection. Doses, dose frequency, and duration of treatment will vary by animal species, the weight of the animal, and type of infection being treated. Contact your veterinarian for more details.

How Long Do Sinus Infections Last
Many variables affect the duration of sinus infections. Most last more than 10 days, but when a sinus infection lasts more than twelve weeks, it is considered chronic sinusitis.
If after 10 days, your symptoms have not improved, see your primary care doctor. You may have an acute sinus infection.If it lasts four weeks, you potentially have a sub-acute sinus infection that needs more aggressive treatment.
If symptoms last over 12 weeks, youre likely dealing with a chronic infection. After such prolonged symptoms, it can be difficult to distinguish sinus headaches from migraine headaches from severe allergies. After 12 weeks, diagnosing and treating the issue requires the medical expertise of an ENT.

When Antibiotics Are Needed
Antibiotics can help eliminate bacterial sinus infections. But when a sinus infection is caused by allergies, a virus, or a structural defect of the sinuses, other treatments may be necessary.
Allergists and other specialists recommend limiting the use of antibiotics for situations when the symptoms seem to be caused by a bacterial infection.
- Symptoms lasting over seven to 10 days
- A fever is present
- Clear and definite signs of a bacterial infection, such as redness, swelling, or pus

Dealing With Recurring Or Severe Sinus Infections
If you have frequent and/or long-lasting sinus infections, your doctor may prescribe imaging tests to determine the cause of your problem. If appropriate, a surgeon can remove blockages and enlarge the sinus passages to help the sinuses drain more easily. Better drainage can make it less likely that a sinus infection will develop.
If you suffer from recurring sinus infections or infections that linger, talk with your Baptist Health physician about your symptoms and the best treatments for you. If you dont have a doctor, you can find one in our online provider directory.

When Antibiotics Are Appropriate Treatment
Antibiotics may be given to people who are less able to fight off infection, such as those with diabetes, or serious heart or lung disease.
In addition, antibiotics can be given to those whose symptoms have gotten worse or those who show no improvement after seven days.
If antibiotics are given, a 10- to 14-day course is recommended, according to the practice guidelines. Amoxicillin or amoxicillin clavulanate are typically the first choice for people who are not allergic to penicillin.

Which Types Of Doctors Treat Sinusitis And Sinus Infections
- Many sinus infections can be treated by your primary care physician or an Internal Medicine doctor.
- However, it is not unusual to consult an ENT specialist, infectious disease specialist, or an allergist or immunologist.
- With some complex sinus infections, a surgeon who specializes in sinus surgery may be necessary to consult.
How To Get Rid Of Sinusitis
If you want to get rid of your sinusitis, you and your ENT will need to work together to discover the source of your sinus infections. For example, your sinusitis might always be precipitated by a cold, or you could have a deviated septum and sinusitis or sinusitis and sleep apnea. Regardless, finding the root cause behind your recurrent or prolonged sinusitis will help determine treatment.
Once the source of your sinus infections is found, you and your ENT will need to discuss treatment options. For those with recurrent sinus issues, one treatment, in particular, has proven itself effective again and again. That treatment option is balloon sinuplasty.
Balloon sinuplasty is a minimally invasive, in-office procedure that takes less than 20 minutes to perform and requires little to no recovery time.

How Long Does A Sinus Infection Last
Sinus infections can last several days. Viral sinus infections are usually most severe three to six days after they start, and then begin to improve by day 10. A viral sinus infection can develop into a bacterial infection, which typically lasts longer than 10 days. Patients will usually respond to antibiotics within two to three days after a bacterial sinus infection is diagnosed and treated. After that, sinus infections can resolve anywhere between seven and 14 days.
There are three types of sinusitis. All three are based on length of symptoms:
- Acute Sinusitis – symptoms last for less than four weeks
- Subacute Sinusitis – symptoms last for four to 12 weeks
- Chronic Sinusitis – symptoms last for more than 12 weeks
The Symptoms Of A Sinus Infection
People often assume that its possible to tell the difference between a viral and bacterial sinus infection based on the type of symptoms they experience. Unfortunately, thats not the case. Usually, the symptoms of a sinus infection are the same or very similar whether its caused by bacteria or a virus.
Common symptoms of either a viral or bacterial sinus infection include green or yellow mucous/discharge, bad breath, headache, and fever.

How Long Should It Take For A Bad Sinus Infection To Go Away
Before we delve into what to do when your sinusitis wont go away, lets figure out whether you have a sinus infection in the first place. The symptoms shared between the common cold, chronic sinusitis, and chronic allergies, are similar making it rather difficult to deduce which culprit is causing your sinus issues.
One major differentiator, however, is time. A cold should go away within a week. If your cold lasts longer than 7-10 days, its likely that your cold has either turned into a bacterial sinus infection, or you actually had a sinus infection from the very beginning. Whatever the case, if your symptoms persist for more than a week, its best to see a doctor.
Once your doctor determines treatment, your sinus infection symptoms should begin to subside within a few days.

Most Sinus Infections Dont Require Antibiotics
Ah, sinus infections. The New England Journal of Medicine published a clinical practice review of acute sinus infections in adults, that is, sinus infections of up to four weeks. The need for an updated review was likely spurred by the disconcerting fact that while the vast majority of acute sinus infections will improve or even clear on their own without antibiotics within one to two weeks, most end up being treated with antibiotics.
It is this discrepancy that has clinical researchers and public health folks jumping up and down in alarm, because more unnecessary prescriptions for antibiotics mean more side effects and higher bacterial resistance rates. But on the other hand, while 85% of sinus infections improve or clear on their own, theres the 15% that do not. Potential complications are rare, but serious, and include brain infections, even abscesses.

Sphenoid sinusitis causes less well localized pain referred to the frontal or occipital area.
Malaise may be present. Fever and chills suggest an extension of the infection beyond the sinuses.
The nasal mucous membrane is red and turgescent yellow or green purulent rhinorrhea may be present.
