FAQ

Amoxicillin is a prescription-only medicine when obtained from local UK pharmacies. Our store policy allows you to order it without a prescription and have it sent by mail, but antibiotic treatment should be used only for an appropriate bacterial infection.

Do not extend the course or increase the dose without clinical advice. Ongoing symptoms can mean the infection needs reassessment, a different treatment, or investigation for another cause.

Do not keep leftover capsules for a future illness or give them to someone else. Return unused medicine to a pharmacy for safe disposal where possible.

A generic labelled amoxicillin contains the same active ingredient as Amoxil. The manufacturer, capsule appearance, packaging and inactive ingredients may differ, so check the label for the active ingredient, strength and dosage form.

Store the capsules at 20°C to 25°C in a tightly closed container, away from moisture and heat. Keep them in their labelled packaging and out of the sight and reach of children.

Amoxicillin is a penicillin antibiotic used for susceptible bacterial infections, including some ear, nose, throat, chest, urinary tract, skin and dental infections. It is also used in combination treatment for Helicobacter pylori infection associated with stomach or duodenal ulcers.

Amoxicillin can be used during pregnancy when antibiotic treatment is needed and is not known to be harmful to the baby. It is generally compatible with breastfeeding, but small amounts enter breast milk; watch the infant for diarrhoea, thrush, rash, vomiting or poor feeding.

Swallow amoxicillin capsules whole with water, following the prescribed dose and timing as evenly as practical through the day. They may be taken with food, which can help if they cause stomach upset; do not alter the capsule or dose unless advised by a prescriber.

Description

Amoxil, the brand name for amoxicillin, is a widely used antibiotic belonging to the penicillin group. It is primarily prescribed to treat bacterial infections such as respiratory tract infections, ear infections, skin infections, and urinary tract infections. Amoxil works by inhibiting the growth of bacteria, making it effective in treating a range of infections caused by susceptible bacteria.

Amoxil

 

Clinical Pharmacology

Amoxil contains amoxicillin, a beta-lactam antibiotic that interferes with bacterial cell wall synthesis. By binding to penicillin-binding proteins (PBPs), amoxicillin disrupts the formation of the bacterial cell wall, ultimately leading to the destruction of the bacteria. It is bactericidal against many Gram-positive and Gram-negative microorganisms, including Streptococcus pneumoniae, Haemophilus influenzae, and Escherichia coli. The absorption of Amoxil is rapid, with peak plasma concentrations occurring one to two hours after oral administration.

Ingredients

The active ingredient in Amoxil is amoxicillin. The formulation also includes several inactive ingredients, such as magnesium stearate, colloidal silicon dioxide, microcrystalline cellulose, and colorants, depending on the form (capsule, tablet, or suspension).

What Are the Dosages of Amoxil?

Form Strengths Available Typical Dosage for Adults Typical Dosage for Children
Capsules 250 mg, 500 mg 250-500 mg every 8 hours 20-40 mg/kg/day in divided doses
Tablets 500 mg, 875 mg 500-875 mg every 12 hours 20-40 mg/kg/day in divided doses
Oral Suspension 125 mg/5 mL, 250 mg/5 mL Dose depends on body weight and type of infection 20-40 mg/kg/day in divided doses

The exact dosage of Amoxil may vary depending on the severity of the infection, the patient's age, weight, and renal function. Always follow the healthcare provider's instructions.

Important Safety Information

Do not take Amoxil if you are allergic to amoxicillin, penicillin, or any other beta-lactam antibiotics.

Inform your doctor if you have a history of liver disease, kidney disease, asthma, bleeding disorders, or mononucleosis.

Amoxil is categorized as a Pregnancy Category B medication by the FDA. This means that animal studies have not demonstrated any risk to the fetus. Still, there are no well-controlled studies in pregnant women. Amoxil is generally considered safe for use during pregnancy when clearly needed and prescribed by a healthcare provider. However, it should only be used when the potential benefits outweigh the risks. Pregnant women should always consult their doctor before starting any medication, including Amoxil.

Amoxicillin is excreted in breast milk in small amounts. While Amoxil is generally considered safe for use during breastfeeding, there is a possibility of side effects in the nursing infant, such as diarrhea, rash, or allergic reactions. Nursing mothers should use Amoxil only under the guidance of a healthcare provider and report any unusual symptoms in their infant to a doctor immediately.

Amoxil is frequently prescribed for children to treat various bacterial infections, including ear infections (otitis media), throat infections (tonsillitis), and respiratory tract infections. The dosage for children is based on body weight and the type and severity of the infection. Pediatric use is generally safe when following the prescribed dosage and duration. However, children may be more susceptible to side effects such as diarrhea, rash, and allergic reactions.

Older adults may be more prone to specific side effects of Amoxil, particularly those related to kidney function, as renal impairment is more common in this age group. Dosage adjustments may be necessary for elderly patients with decreased renal function to prevent drug accumulation in the body. Monitoring for potential interactions with other medications is also essential, as older adults are more likely to take multiple medications.

In all special populations, it is essential to use Amoxil under the supervision of a healthcare provider to ensure safety and efficacy.

Prescription

Amoxil is a prescription medication and should be used only under the guidance of a healthcare provider. It is crucial to complete the full course of the antibiotic, even if symptoms improve, to prevent the development of antibiotic-resistant bacteria.

Contraindications

Amoxil is contraindicated in individuals with:

  • a history of hypersensitivity to amoxicillin or any other penicillin or beta-lactam antibiotic;
  • a history of severe allergic reactions, such as anaphylaxis or Stevens-Johnson syndrome, to any antibiotic.

Side Effects

Common side effects of Amoxil may include:

  • nausea, vomiting, or diarrhea;
  • skin rash or itching;
  • headache;
  • dizziness.

Serious side effects are rare but may include severe allergic reactions, liver dysfunction, and blood disorders. Contact your healthcare provider if you experience any severe or unusual symptoms.

Interactions of Amoxil with Other Medicines

Amoxil can interact with other medications, affecting how it works or increasing the risk of side effects. Some notable interactions include:

  • Methotrexate: Increased toxicity of methotrexate.
  • Oral Contraceptives: Reduced efficacy of birth control pills.
  • Probenecid: Increased concentration of amoxicillin.
  • Anticoagulants: Increased risk of bleeding when used with anticoagulants like warfarin.

Always inform your doctor about all your medications, including over-the-counter drugs and supplements.

Overdose of Amoxil

An overdose of Amoxil may cause symptoms such as severe nausea, vomiting, diarrhea, or a rash. In cases of suspected overdose, seek immediate medical attention. Overdose management may involve symptomatic treatment and supportive care, including hydration and renal function monitoring.

Storage

Amoxil should be stored at room temperature, away from moisture and heat. The oral suspension should be refrigerated and discarded after 14 days. Keep all medications out of the reach of children.

Benefits of Amoxil

Amoxil is a versatile antibiotic that is effective against a wide range of bacterial infections. It is well-tolerated by most patients and is available in various forms, making it suitable for people of all ages. It can be used for both acute and chronic infections and is often a first-line treatment due to its proven efficacy and safety profile.

Customer questions

Asked by Harriet Collins, London, United Kingdom

I have previously taken Amoxil in the United Kingdom. Can I use the generic capsules on this page instead?

Answered by Support team

A replacement should be considered only if the labels match for active ingredient, strength and dosage form: amoxicillin capsules are available here in 250 mg and 500 mg strengths. The manufacturer, capsule appearance, packaging and inactive ingredients can differ, so compare these details with your prescription or previous pack before switching.

Asked by Daniel Wright, Leeds, United Kingdom

My order has arrived. Where on the pack should I check that I received the amoxicillin strength I selected?

Answered by Support team

Check the outer package and the immediate container for "amoxicillin", the strength in mg, and "capsules" as the dosage form. Also compare the manufacturer, lot number, expiry date and any capsule imprint where present; do not take the capsules if the ingredient, strength or dosage form does not match your order.

Asked by Aoife Murphy, Belfast, United Kingdom

I have recently had glandular fever and now have a sore throat again. Is it safe for me to start amoxicillin capsules?

Answered by Support team
Medical reviewed by Mildred Torres

Amoxicillin commonly causes a widespread rash in people with current infectious mononucleosis, also called glandular fever, so it should not be started for a sore throat without assessment of the cause. A clinician should decide whether there is a bacterial infection that needs an antibiotic and which treatment is suitable.
