Will Sinusitis Go Away Without Antibiotics?

Sinusitis, a sinus infection, affects millions of people worldwide each year. Many wonder if sinusitis can go away without antibiotics.


The answer to “Will sinusitis go away without antibiotics?” is not a straight yes or no. It depends on various factors like

  • individuals’ condition – the intensity of the disease

  • stage of the disease

  • type of the disease – fungal or bacterial

  • immunity of the person

  • luck of the patient too


So, it is very unpredictable. An ENT doctor will have one of the two answers to this question.

  1. Maybe your sinusitis might go away without antibiotics

  2. No, your sinusitis will not go away without antibiotics


Will Sinusitis Go Away Without Antibiotics?


Causes of Sinusitis

There are three major causes of sinusitis.

  1. Allergy

  2. Anatomical Anomalies in the sinus drainage pathway

  3. Low immunity against bacteria from birth


People can have single or multiple causes among the three.


When individuals with these conditions develop a nasal infection, the mucosa lining the nose and sinuses becomes swollen. This swelling can lead to sinusitis, where fluids become trapped in the sinuses. Bacteria can then grow in these sinuses, infecting the sinus walls and causing further swelling. As the swelling increases, more sinuses can be blocked, starting a vicious cycle.

Can Sinusitis Heal Naturally?

In most cases, sinus infections can resolve on their own within the first 15 days if proper remedies are followed, even without antibiotics or medical intervention.


However, if your symptoms only reduce in intensity or number instead of disappearing completely, it's important to consult an ENT specialist immediately. In such cases, antibiotic treatment may be necessary.


If the infection doesn't clear up within the first 15 days, there's a higher chance it may progress to chronic sinusitis, which can lead to complications. Chronic sinusitis often requires antibiotics and sometimes even sinus surgery.


So, if your symptoms persist or worsen, it's best to seek medical advice to prevent complications.

Antibiotics Usage for Sinusitis to Go Away

Here, we have given generalized information regarding the antibiotic course used for sinusitis treatment.

Start the medication from the onset of the disease

Duration of antibiotics course

0-15 days from the start of the disease

At least 10 days

or till 5 days after the symptoms completely disappear

15-45 days

Minimum 15 days or till, 5 days after the symptoms completely disappear

Above 45 days

2 weeks to 6 months


Although the duration of the course might sound scary, the antibiotics used to treat sinus infections are relatively safe and milder.


Milder antibiotics with longer duration over stronger antibiotics with shorter duration is the choice made by ENTs for sinusitis. So, even if 6 months of antibiotics are prescribed, the side effects are almost nil.


How do you know if you need antibiotics for a sinus infection?

In the early stages of sinusitis, treatment options may vary based on the severity of the infection. While some ENT specialists may consider a wait-and-see approach, Dr. K. R. Meghanadh strongly recommends treating sinusitis with antibiotics. According to him, it is difficult to predict the course of the disease, and using antibiotics can help prevent complications. Additionally, Dr. Meghanadh believes that the medication required in the early stages is minimal and manageable, making it safer to use antibiotics rather than risking the infection worsening by avoiding them.

He highly recommends adding natural home remedies to the treatment, as the remedies are very effective and can decrease the course of antibiotics and prevent complications.


After the 15-day mark, sinusitis enters from the acute to subacute stage. The likelihood of this infection continuing to the chronic stage without subsiding is on the higher side. In some cases, past of the 15-day mark, a minor surgery could be opted for just to prevent the transition from subacute to chronic stage.

What happens if you let a sinus infection go untreated?

Leaving a sinus infection untreated or partially can lead to complications like spreading to the lungs, voice box, ears, eyes, and brain. Although complications with the brain and eyes are rare, getting treated when we experience any symptoms is better.

As mentioned earlier, the antibiotics for sinusitis are mild and mostly don’t have side effects, but the same cannot be said for the antibiotics required for complications of sinusitis.


Asthma is one of the complications of sinusitis. While sinusitis is a temporary condition, once asthma onsets, the condition is permanent. The medication will have side effects. Some people might think that their asthma is healed, but it is just part of asthma’s life cycle; at some point of time in their life, it will start acting up.

How to increase the chances of eliminating Sinusitis without antibiotics?

Home remedies and anti-allergic medications can help treat sinusitis without antibiotics.

The effectiveness of these methods depends on various factors, so they can increase the probability of relief but are not a guaranteed solution.

Home Remedies

As mentioned earlier, home remedies for sinus infections are very effective and can either help in faster recovery or even eliminate the need for antibiotics in the early stages.

  1. Steam inhalation

  2. doing multiple workouts daily

  3. Improving our immunity with spices

  4. Staying hydrated

  5. Adequate sleep

Anti-allergic medication

Many people with sinusitis have allergies, which is one of the three causes of the infection. In such people, anti-allergic medication can help control the allergy and further help in controlling the disease thereby increasing the chances of recovery without antibiotics.

Anti-allergic medication is a very safe medication compared to the medication required for the complications that can come with an allergy.


In summary, whether sinusitis resolves without antibiotics depends on several factors. The body's immune system can often fight the infection, but bacterial sinusitis may require antibiotics to prevent complications. Seeking medical attention if symptoms persist or worsen is crucial for effective management and to prevent further issues.

Doctors typically prescribe mild and safe antibiotics for several weeks for sinusitis, preferring this approach over stronger antibiotics for a shorter duration. The risk of side effects with these antibiotics is minimal, and even if they occur, they are usually not severe.
