Amoxicillin is an oral antibiotic that treats a range of bacterial infections, including nasal infections.
Nose infections are often caused by the bacteria Staphylococcus aureus. This bacteria is part of your microbiome and is usually harmless. But when it enters your body through a break in the skin, it can lead to infections. While most infections are mild, some can become serious.
Bacterial infections often resolve on their own, but if your symptoms persist or worsen, you’ll need to treat them with antibiotics.
How does Amoxicillin treat nasal infections?
Amoxicillin is a penicillin antibiotic that inhibits transpeptidation, a process that bacteria use to build their cell wall. Without a cell wall, bacteria can’t grow and eventually die.[1]
You must finish your full course of antibiotics to prevent re-infection. Even if you feel better, there’s a chance the bacteria is still in your body. Finishing the course of antibiotics ensures the bacteria is completely gone.
What doses of Amoxicillin are there?
Amoxicillin is available in two doses: 250mg and 500mg. The dosage you’ll be given varies depending on the severity of your infection. For adults, it’s typically 250mg to 500mg three times a day for a week.

How to take Amoxicillin
To take Amoxicillan:
Swallow the tablet whole with water.
It can be taken on an empty stomach, but taking it with food may help reduce side effects.
Space out your doses throughout the day.
You should complete your full course of antibiotics even if you feel better. This ensures the bacteria is completely gone and prevents reinfection.
If you don’t feel better after you finish treatment, let your doctor know. You may need another round of antibiotics.
How long does Amoxicillin take to work?
Although Amoxicillin starts to work immediately, it will take around three days to notice an improvement in your symptoms.
I made a mistake when taking Amoxicillin, now what?
If you took more than the prescribed dose, you might experience side effects, such as:
an upset stomach,
nausea,
cloudy urine,
diarrhoea,
problems urinating.
Contact your doctor for medical advice if you experience any side effects.
If you forget to take a dose, don’t worry. Take the missed dose as soon as you remember and wait at least four hours before taking the next dose. Taking two doses close together increases the risk of side effects. Don’t take a double dose to make up for a missed one.

Amoxicillin: FAQ
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
Will I get side effects from taking Amoxicillin?
Answer:
There's a risk of experiencing side effects with Amoxicillin, including:
skin rash,
nausea,
diarrhea, and
vomiting.
Taking it with food and spacing out the doses may help manage some of the side effects. The side effects should go away when your treatment finishes, but if they continue, contact your doctor for medical advice.
Is it safe to drink alcohol while taking Amoxicillin?
Answer:
You can drink alcohol while taking Amoxicillin, but it may worsen the side effects for some people.
What is Amoxicillin used for?
Answer:
Amoxicillin can treat several bacterial infections, including thrush, skin infections, sinusitis and dental abscesses.
Completing the full course of Amoxicillin is important. Stopping the treatment early can increase your risk of reinfection and antibiotic resistance. When bacteria become resistant to an antibiotic, that antibiotic can no longer effectively treat the infection. This makes it harder to treat future infections.
How does Amoxicillin differ from other treatments for nasal infections?
Answer:
Amoxicillin is an oral antibiotic often used to treat nasal infections. A similar treatment is Augmentin, which contains amoxicillin and clavulanic acid. The addition of clavulanic acid enhances its antibacterial properties. Both antibiotics are similarly effective, but Augmentin may cause more side effects.[1]
If Amoxicillin doesn't work well for you, you can try different antibiotics like Cefdinir and Doxycycline.
Is Amoxicillin available without a prescription?
Answer:
No, like all antibiotics, you will need a prescription for Amoxicillin. This is so your doctor can check the medication is safe and suitable for you to use. It also prevents antibiotic misuse, which can contribute to bacterial resistance.
