What Is Amoxicillin?
Amoxicillin is a penicillin-type antibiotic widely used to combat bacterial infections. Manufactured by several pharmaceutical companies including GlaxoSmithKline and Teva Pharmaceutical Industries, it contains amoxicillin trihydrate as its active ingredient. Think of it as a targeted strike force against unwelcome bacteria in your system. It’s prescribed for a broad spectrum of conditions – from common ear infections and sore throats to more serious respiratory tract infections like pneumonia, and even certain skin ailments.
Amoxicillin doesn’t just magically eliminate the infection; it actively interferes with the bacteria’s ability to build their cell walls. Without these walls, the bacteria become vulnerable and eventually die off, allowing your body’s natural defenses to finish the job. It’s a cornerstone treatment in many GP surgeries across the UK, and its effectiveness has been proven over decades of use.
The prevalence of bacterial infections requiring antibiotic intervention remains significant; recent NHS data (2024) indicates approximately 15% of all consultations with GPs involve suspected or confirmed bacterial infections treatable with antibiotics like amoxicillin. This highlights the continued importance of having access to effective treatments. It’s important to remember that Amoxicillin is ineffective against viral infections, such as the common cold or flu.
Forms and Dosages
Amoxicillin comes in several forms to suit different patient needs. The most common are capsules and tablets, available in strengths ranging from 125mg to 500mg. You’ll also find it as an oral suspension (liquid) – particularly useful for children or those who struggle swallowing pills. Injectable formulations exist but are typically reserved for hospital settings where rapid administration is crucial.
Here’s a breakdown of common dosage forms:
| Form | Strength(s) | Administration | Splittable? |
|---|---|---|---|
| Capsules | 250mg, 500mg | Swallow whole with water. | No |
| Tablets | 125mg, 250mg, 500mg | Swallow whole with water. Some scored tablets can be split. | Sometimes (scored only) |
| Oral Suspension | 60mg/mL, 125mg/mL, 250mg/mL | Measure dose accurately using provided syringe or spoon. Shake well before use. | N/A |
| Injection | Varies (hospital use only) | Administered by a healthcare professional. | N/A |
Dosage is highly individual, determined by the severity of infection, patient age, kidney function and overall health. Always follow your doctor’s instructions precisely – don’t try to self-adjust the dose or duration of treatment. "I always tell my patients," says Dr. Anya Sharma, a London GP, “it’s better to finish the course even if you feel better, otherwise some bacteria might survive and become resistant.”
Who Can Take It?
Generally, amoxicillin is suitable for both men and women, and children of all ages – though dosage adjustments are vital for younger patients. However, caution is advised in certain groups. The elderly may have reduced kidney function, requiring lower doses to prevent side effects. Pregnant or breastfeeding women should discuss the risks and benefits with their doctor before taking amoxicillin; while generally considered safe, careful evaluation is essential.
Individuals with a history of allergic reactions to penicillin or cephalosporin antibiotics must not take amoxicillin. It’s also important to inform your doctor if you have kidney problems, liver disease, or any other significant medical condition before starting treatment. A thorough medical history helps ensure the medication is safe and effective for you.
How to Take Amoxicillin
Amoxicillin can be taken with or without food, but taking it with a meal might help reduce potential stomach upset. Consistency is key; take your doses at roughly the same time each day. For oral suspensions, always use the measuring device provided – kitchen spoons aren’t accurate enough! The typical course of treatment ranges from 7 to 14 days, depending on the infection type and severity.
If you miss a dose, take it as soon as you remember, unless it’s almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular schedule. Do not double up on doses to catch up – this can increase the risk of side effects. Completing the full course is crucial, even if symptoms improve before you finish all the medication.
How It Works
Imagine bacteria as tiny builders constructing a fortress around themselves - their cell walls. Amoxicillin acts like a saboteur, blocking the enzymes these bacteria need to build and maintain those walls. This weakens the structure, eventually causing the bacterial cells to rupture and die. It’s a targeted attack that doesn’t harm your own body’s cells because they don’t use the same building process.
This mechanism classifies amoxicillin as a beta-lactam antibiotic. Beta-lactams disrupt peptidoglycan synthesis – a vital component of bacterial cell walls. By inhibiting this process, Amoxicillin effectively halts bacterial growth and proliferation, allowing your immune system to clear the infection. It’s a clever bit of biological warfare!
Contraindications
Certain conditions absolutely preclude the use of amoxicillin. Anyone with a known allergy to penicillin or any other beta-lactam antibiotic (like cephalosporins) should never take it. This is because cross-reactivity can occur, leading to severe allergic reactions.
Individuals with a history of infectious mononucleosis ("mono") shouldn’t receive amoxicillin as it can cause a characteristic rash. Similarly, those with certain genetic conditions affecting red blood cell function (e.g., hereditary spherocytosis) should avoid it due to increased risk of haemolytic anaemia. It’s vital to be upfront with your doctor about any allergies or medical history.
Interactions
Amoxicillin can interact with other medications and even some foods. Probenecid, a medication used for gout, can increase amoxicillin levels in the blood, potentially leading to side effects. Certain antibiotics, like tetracyclines, may reduce amoxicillin’s effectiveness.
While moderate alcohol consumption isn’t typically dangerous while taking amoxicillin, excessive drinking can worsen potential side effects like nausea and stomach upset. Avoid grapefruit juice as it may interfere with the metabolism of some medications, although this interaction is less well-established with amoxicillin specifically. Always inform your doctor about all medications, supplements, and dietary habits you have.
Side Effects
Like all medicines, amoxicillin can cause side effects. Common ones include nausea, vomiting, diarrhoea, and skin rash – these are usually mild and resolve on their own. Less common side effects might involve dizziness or headache.
However, serious side effects require immediate medical attention. These include severe allergic reactions (hives, swelling of the face/tongue/throat, difficulty breathing), severe diarrhoea (potentially indicating Clostridium difficile infection), and signs of liver problems (yellowing of skin/eyes). If you experience any concerning symptoms, don’t hesitate to seek help.
Overdose Risks
An amoxicillin overdose is rare but possible. Symptoms can include nausea, vomiting, abdominal pain, diarrhoea, and in severe cases, seizures or kidney problems. If you suspect an overdose, immediately contact your local poison control centre or go to the nearest emergency room. Do not attempt to induce vomiting unless instructed by a medical professional.
Price and Availability
The price of amoxicillin varies depending on dosage strength, quantity purchased, and pharmacy location. A typical 7-day course of 250mg capsules can range from £8 to £15 in the UK (as of late 2025). Online pharmacies often offer competitive pricing, such as Amoxicillin at medicade.co.uk. It’s available at most retail pharmacies across the UK with a valid prescription.

Alternatives
If you’re allergic to penicillin or amoxicillin isn’t suitable for you, several alternatives exist. Other antibiotics like erythromycin, azithromycin (macrolides), or ciprofloxacin (quinolones) may be considered. Natural remedies such as garlic and honey have some antibacterial properties but are not a substitute for prescribed medication in treating serious bacterial infections. They can potentially offer supportive care alongside conventional treatment.
Precautions
Store amoxicillin at room temperature, away from moisture and direct sunlight. Always complete the full course of treatment, even if you feel better. Inform your doctor about any allergies or medical conditions before starting amoxicillin. Avoid taking it with other medications without consulting your doctor first. Discard any unused medication properly – don’t flush it down the toilet.
