Understanding Amoxicillin for Sinus Infection Relief

Could that persistent sniffle be your springtime allergies acting up — or is it something more serious, like a sinus infection?

If you’re one of the 28.9 million Americans who get sinus infections each year, you’ll know how frustrating they can be to treat.

Fortunately, there are several treatments and management techniques you can use to feel better again.

In this article, we’ll look at amoxicillin and how it can be used to treat sinus infections. We’ll also explore some alternatives for people with penicillin allergies and management techniques for those who prefer to monitor their symptoms before commencing treatment.

What is Amoxicillin?

Amoxicillin is a widely used antibiotic that belongs to the penicillin group. It works by disrupting bacterial cell wall formation, rendering the bacteria vulnerable and aiding the immune system in clearing the infection.

This antibiotic is suitable for both children and adults, and the recommended dosage and form depend on factors like age, weight, and the specific ailment being treated.

You can find amoxicillin in various forms such as capsules, tablets, and liquid solutions. This versatile antibiotic is prescribed for many conditions, including:

• Ear infections
• Throat infections
• Tooth infections
• Skin-related infections
• Infections in the lower respiratory system

What is a Sinus Infection?

Also known as sinusitis or rhinosinusitis, a sinus infection refers to inflammation and swelling of the sinuses, which are the air-filled cavities located in the face and skull.

During a sinus infection, fluid accumulates in the sinuses, leading to increased pressure and promoting bacterial growth.

Viruses, fungi, allergies, and structural abnormalities of the nose — such as nasal polyps or a deviated septum — can all lead to sinus infections.

Sinus infections may be mild and treatable with over-the-counter (OTC) medications, or they may be severe and require prescription medications or surgical intervention.

A long-lasting sinus infection is called chronic sinusitis, while a sinus infection that keeps returning is called recurrent acute sinusitis (RARS). People with RARS typically experience four or more sinusitis episodes per year and may have persistent symptoms year-round.

Acute bacterial sinusitis — bacterial sinus infections lasting three to eight weeks — typically respond well to antibiotic treatment. Your doctor may prescribe other treatments for chronic, recurrent, or severe sinusitis.

Amoxicillin for Sinus Infection: Is it a Good Treatment?

Amoxicillin is the recommended first-line treatment for sinus infections in both adults and children. When used to treat sinusitis, amoxicillin has an efficacy rate of 80–90%.

Another recommended treatment is amoxicillin-clavulanate (Augmentin®) — a combination therapy with an efficacy rate of more than 90%.

Sinus infections are mainly treated with antibiotics, but the treatment your doctor prescribes will vary based on the type and severity of your sinus infection.

Amoxicillin and augmentin will not be prescribed to people with penicillin allergies.

How long does it take for a sinus infection to resolve with amoxicillin?

Most people who take amoxicillin to treat acute bacterial sinusitis will begin feeling better 2–4 days after they’ve started the medication.

Symptoms like facial pain or pressure, nasal congestion, and thick mucus will start to clear within the first few days.

It will take between 10–14 days, or the duration of your antibiotic course, for the infection to completely resolve. This will differ between patients, depending on your doctor’s advice.

Amoxicillin for sinus infections: Possible risks and side effects

There’s always the risk of an allergic reaction when using medications, and antibiotics like amoxicillin are no exception.

People with known penicillin allergies should not use this treatment.

Always disclose any medication you’re currently taking before your doctor prescribes amoxicillin for your sinus infection.

Potential side effects of amoxicillin include:

• Allergic reactions – ranging from itching and mild rashes to severe reactions that include facial swelling and breathing difficulties — these require emergency medical attention.
• Digestive issues, like nausea, diarrhea, and vomiting.
• Superinfections or secondary infections, like fungal infections, that are unrelated to sinus infections. People who are immune-compromised have an increased risk of secondary infections and should exercise caution when using amoxicillin.
• Headaches and taste disturbances.

How Do I Use Amoxicillin to Treat Sinus Infection?

Amoxicillin dosages differ for adults and children. Doctors will typically prescribe capsules or tablets for adults and liquid suspensions for children.

Adult dosage:

• Amoxicillin 500 mg, twice per day, every 12 hours

Pediatric dosage:

• Amoxicillin 25–45 mg/kg, in divided doses as per your doctor’s directions

Pediatric doses of amoxicillin are determined based on the child’s weight. Your doctor will provide further instructions.

Amoxicillin can be mixed with baby formula, food, water, or juice to make it more palatable when administering it to children.

What happens if I miss a dose of amoxicillin?

It’s not advisable to skip doses or to stop taking amoxicillin if you start feeling better before you’ve completed your course.

Should you forget to take a dose, you can do one of the following:

If you remember you’ve missed a dose and it’s nearly time to take your next one, skip the missed dose and resume your regular dosing schedule.

OR

If there’s plenty of time before your next scheduled dose, go ahead and take the missed dose.

Never double dose and always properly dispose of any leftover antibiotics. You should not share antibiotics or save them for future infections.

How to Treat Sinus Infections: Alternative Treatments

If you don’t want to use amoxicillin for treating a sinus infection — or you can’t, due to allergies — there are several other treatment options available.

When you book a consultation with your doctor, they’ll walk you through these alternative treatments and prescribe what’s best for you.

Medication

For those with penicillin allergies, alternative antibiotics include:

• Levofloxacin
• Moxifloxacin
• Clindamycin
• Doxycycline
• Cefprozil
• Azithromycin
• Clarithromycin
• Erythromycin

All the above mentioned drugs have been proven to be incredibly effective for treating sinus infections.

The type of antibiotic your doctor prescribes will depend on whether you’re treating an acute, chronic, or recurrent infection.

Home therapies or natural remedies

The Centers for Disease Control and Prevention (CDC) recommends watchful waiting, as most sinus infections will clear on their own, so antibiotics aren’t always necessary.

However, people with severe or worsening symptoms and persistent fever for more than three days, should seek medical care.

If you keep having sinus infections, there may be an underlying cause, like a structural abnormality that needs to be addressed by a medical professional — in cases like these, home remedies and even medications won’t offer lasting relief.

For mild or uncomplicated sinus infections, you could try the following at-home treatments:

• Inhale warm steam from a bowl or during a hot shower
• Use a saline nasal rinse or spray to flush out your sinuses
• Apply a warm compress to your nose and forehead to relieve sinus pressure
• Use OTC decongestants, antihistamines, and pain medication like acetaminophen

  Management strategies

The following management techniques may also help prevent sinus infections in the long-term:

• Identify your triggers: Determine which factors contribute to your sinus infections.
• Invest in a humidifier: Adding moisture to the air can help reduce congestion and prevent nasal irritation.
• Drink enough water: When you drink enough fluids, your mucus will be thinner, thereby minimizing congestion — just remember to avoid dehydrating beverages like coffee and alcohol.
• Be sure to get enough vitamins and minerals, especially vitamin C.

Can Sinus Infection Go Away on its Own?

The consensus among physicians and specialists is that most sinus infections will resolve naturally without antibiotics or other treatments.

Unless you have severe symptoms, most doctors recommend a period of watchful waiting before taking medications and antibiotics.

Watchful waiting is a strategy that entails monitoring and assessing a patient’s condition first and holding off on prescribing treatment, thereby giving the body a chance to fight the infection and heal on its own.

The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) strongly recommends watchful waiting as a management strategy for sinusitis.

However, they do advise that this method only be used if the patient agrees to a follow-up visit that allows the doctor to reassess their condition.

When Should You Visit a Doctor for a Sinus Infection?

Sinus infections can cause great discomfort and make it difficult to perform daily tasks. If you have a serious or recurrent sinus infection, we advise you to speak to your doctor.

If your symptoms improve with OTC medication or without any treatment, and these symptoms do not recur, you may have a mild sinus infection that does not require a doctor’s visit.

Amoxicillin: What are the Dangers of Using This Antibiotic for Sinus Infections?

If you experience sinus infections once in a while, antibiotics should be safe to use. However, people with chronic or recurrent infections should be mindful of overusing antibiotics.

Amoxicillin is an antibiotic that has been widely overprescribed. Overuse of antibiotics contributes to antibiotic resistance, which is a serious concern for the CDC.

Antibiotic resistance occurs when bacteria evolve to withstand the effects of antibiotics, rendering treatments less effective or ineffective.

Your doctor may prescribe alternative treatments or surgical interventions if your sinus infections keep coming back or do not improve with antibiotics.
