What Is Amoxicillin 250mg/5mL?

Amoxicillin is a penicillin-class antibiotic that works by stopping the growth of bacteria. The 250mg/5mL suspension is a liquid form that is measured with a dosing device, making it a common choice for children and for adults who have difficulty swallowing tablets. It is FDA-approved for a range of bacterial infections, including infections of the ears, nose, throat, lower respiratory tract, skin, and urinary tract. Because searches for amoxicillin and prednisone are common, note that prednisone is a separate steroid medication; only a healthcare provider can determine whether combining them is appropriate for you.

What Does Amoxicillin 250mg/5mL Treat?

Sinus infections (bacterial sinusitis)
Ear infections (otitis media)
Throat infections (strep throat, tonsillitis)
Lower respiratory tract infections (pneumonia, bronchitis caused by susceptible bacteria)
Skin and skin structure infections
Urinary tract infections
H. pylori infection (as part of combination therapy)

Amoxicillin 250mg/5mL Dosage

Mild to moderate infections (ENT, skin, urinary tract): 250 mg (5 mL) by mouth every 8 hours, or 500 mg every 12 hours.
Severe infections or lower respiratory tract infections: 500 mg by mouth every 8 hours, or 875 mg every 12 hours.
Take for the full duration prescribed; shake suspension well before each dose.

Frequently Asked Questions

Can you take amoxicillin and prednisone together?

Amoxicillin and prednisone are sometimes prescribed together because they treat different problems — amoxicillin fights bacterial infection while prednisone reduces inflammation. There is no major known interaction between them, but you should only take both if your prescriber directs you to. Always tell your provider about all medications you take.

Are amoxicillin and prednisone for sinus infection an effective combination?

For some bacterial sinus infections with significant inflammation, a prescriber may pair amoxicillin with a short course of prednisone. Amoxicillin targets the bacteria while prednisone can reduce swelling and congestion. This decision depends on your specific case and should be made by a healthcare provider.

Can I take amoxicillin and prednisone for tooth infection?

Amoxicillin is commonly prescribed for dental infections caused by susceptible bacteria, and a dentist or physician may occasionally add prednisone to manage severe inflammation. Do not combine them on your own — follow the exact regimen your prescriber gives you. Dental infections also often require a dental procedure to fully resolve.

Do I need a prescription for Amoxicillin 250mg/5mL?

Yes. Amoxicillin is a prescription-only antibiotic in the United States. A licensed provider must review your health information and confirm the medication is appropriate before it can be dispensed.

How does ordering and shipping work?

After you place your order, a licensed provider reviews your information (or your existing prescription is verified). Once approved, your medication is dispensed and shipped from a licensed U.S. pharmacy to your door.

How should I take the amoxicillin suspension?

Shake the bottle well before each dose and measure with the provided dosing device, not a household spoon. It can be taken with or without food, and taking it with food may reduce stomach upset. Finish the entire prescribed course even if you feel better.

What should I do if I miss a dose?

Take the missed dose as soon as you remember, unless it is almost time for your next dose. Do not take two doses at once to make up for a missed one. Contact your pharmacist if you are unsure.
