Fleming 1000mg: Uses, Dosage, Side Effects & Price in Nigeria

Fleming 1000mg is a prescription antibiotic that pairs two active ingredients to treat bacterial infections. Amoxicillin is a widely used penicillin-type antibiotic, while clavulanic acid stops bacteria from breaking the antibiotic down. This article covers what the medicine is, how it is taken, safety precautions, and possible side effects.

Mechanism of action of Fleming 1000mg

Fleming 1000mg is an antibiotic that kills the bacteria behind an infection. Each tablet contains two medicines that work synergistically: 875mg of amoxicillin and 125mg of clavulanic acid.

  • Amoxicillin (the bacteria killer)

 Amoxicillin belongs to the penicillin family (β-lactam antibiotics). It latches onto penicillin-binding proteins in the bacterial cell wall, which bacteria rely on to link up and reinforce their walls. Once these proteins are blocked, the wall can’t be completed; it weakens, and the bacteria burst and die.

  • Clavulanic acid (the bodyguard)

 On its own, clavulanic acid does little against bacteria, but its protective role is important. Many bacteria make enzymes called β-lactamases, which break apart the β-lactam ring in antibiotics like amoxicillin and make them useless. Clavulanic acid attaches to these enzymes and disables them for good, leaving amoxicillin free to do its job.

The combined effect is a broader-spectrum antibiotic. Together, the two medicines act against β-lactamase-producing Gram-positive bacteria, Gram-negative bacteria, and anaerobic bacteria such as Bacteroides species.

Indications: What Is Fleming 1000mg Used For?

Fleming 1000mg is prescribed when an infection is caused by bacteria that respond to it. Doctors most commonly use it for the following.

  • Typhoid fever. It can be used, but only when laboratory tests confirm that the typhoid bacteria are sensitive to co-amoxiclav (amoxicillin with clavulanic acid).
  • Skin and soft tissue infections. This includes cellulitis and wounds that have become infected.
  • Urinary tract infections (UTIs). It treats bacterial infections of the bladder and, in more serious cases, the kidneys.
  • Respiratory tract infections. It is often used for sinusitis, bronchitis, and pneumonia, where bacteria have settled in the airways or lungs.
  • Dental infections. It is a frequent choice for painful tooth abscesses and gum infections, especially severe ones.
  • Bone and joint infections. It may also be prescribed when bacteria have infected the bones or joints.

Because the right antibiotic depends on the bacteria involved, Fleming should only be taken when prescribed.

Contraindications: Who Should Not Take Fleming 1000mg

Before you start Fleming 1000mg, there are some safety points to keep in mind, including who should avoid it, which conditions need care, and which medicines can interact with it.

Do not take Fleming 1000mg if you:

  • Are allergic to amoxicillin, clavulanic acid, penicillin, or any other ingredient in the tablet
  • Have ever had a severe allergic reaction to another antibiotic
  • Have had liver problems or jaundice while on antibiotic treatment
  • Have glandular fever
  • Are being treated for liver or kidney problems
  • Have difficulty passing urine

Your doctor may also order tests to identify the bacteria causing your infection and adjust your treatment if needed.

Other precautions

  • Fleming 1000mg can make some existing health conditions worse and may cause serious side effects such as allergic reactions, seizures, or inflammation of the large intestine.
  • It can affect certain blood and urine test results. If you have tests coming up, such as liver function, red blood cell count, or urine glucose, tell the medical staff you are taking Fleming 1000mg.
  • Some medicines can interact with it, including gout treatments, blood thinners, methotrexate, and transplant rejection drugs.

Taking other medicines


Let your doctor or pharmacist know about any medicines you are using, have used recently, or may start using.

  • Allopurinol (for gout): may raise the chance of allergic skin reactions.
  • Probenecid (for gout): your doctor may need to adjust your Fleming dose.
  • Blood thinners (e.g., warfarin): extra blood tests may be needed.
  • Methotrexate (for cancer or autoimmune conditions): Fleming may change how it works.
  • Mycophenolate mofetil (to prevent organ transplant rejection): Fleming may make it less effective.

Pregnancy, breastfeeding, and fertility: If you are pregnant, breastfeeding, think you may be pregnant, or are planning a pregnancy, speak to your doctor or pharmacist before taking Fleming.

Driving and using machines: Some side effects can affect your ability to drive or handle machinery. If you feel unwell, avoid these activities.

Propylene glycol: Each tablet contains 4mg of propylene glycol.

Side effects of Fleming 1000mg

Like most medicines, Fleming 1000mg can cause side effects, although not everyone gets them. Most are mild and clear up on their own. Some people develop skin reactions or allergic responses, and in rare cases a reaction can be serious enough to need urgent medical care.

Common side effects include:

  • Nausea
  • Vomiting
  • Diarrhoea
  • Rash or itching
  • Vaginal thrush or discharge
  • Diaper rash in children

Serious reactions to watch for:

  • Hives, difficulty breathing, or swelling of the face or throat
  • A painful red or purple rash, blistering, or peeling skin
  • Fever with a sore throat or burning eyes
  • Yellowing of the skin or eyes (jaundice)
  • Unusual bleeding or bruising
  • Muscle aches or severe weakness
  • Persistent or bloody diarrhoea, which may point to a C. difficile infection

Fleming 1000mg Dosage

Fleming 1000mg is typically reserved for severe infections, where a higher dose of antibiotic is needed to bring the illness under control. Taking the correct dose is essential as it helps the antibiotic work as intended, reduces the risk of side effects, and lowers the chance of antibiotic resistance developing.

To get the most from your Fleming 1000 mg treatment, keep the following guidelines in mind:

  • Adults and children weighing 40 kg or more: usually 1 tablet every 12 hours, twice a day.
  • Children under 40 kg: the tablets are not suitable. A suspension or lower-strength form is usually used instead.
  • Kidney or liver problems: the dose may need adjusting, and closer monitoring may be required.

Finish the full course, even if you start feeling better early. Stopping too soon can allow the infection to return or the bacteria to become resistant.

Fleming 1000mg price in Nigeria

Fleming 1000mg typically costs between ₦7,000 and ₦14,000 in Nigeria. The actual price may vary depending on the pharmacy, location, and pack size. For the most current price and availability.

Frequently Asked Questions

This section answers common questions about Fleming 1000mg in simple terms. It is general guidance, so always follow your doctor’s or pharmacist’s instructions for your own situation.

  • What should I do if I miss a dose?

 Take it as soon as you remember. If it is almost time for your next dose, skip the missed one and carry on as normal. Don’t double up, as this raises the risk of side effects without making the treatment work better.

  • Can Fleming 1000mg be used for UTIs?


Yes, as Fleming 1000mg works well against some of the bacteria that cause UTIs, but not all of them, so it isn’t the right choice for every infection. Your doctor will decide based on your symptoms and, if needed, a urine or bacterial susceptibility test.

  • Does Fleming affect fertility?


Fleming 1000mg does not harm fertility in men or women. If anything, one study found that amoxicillin with clavulanic acid could clear bacterial infections in semen, which might improve sperm health in some men.

  • Fleming 1000mg or Fleming 625mg: which one should I take?


Both contain amoxicillin and clavulanic acid at different strengths. Fleming 625mg has 500mg of amoxicillin and 125mg of clavulanic acid, while Fleming 1000mg has 875mg of amoxicillin and 125mg of clavulanic acid. The right choice depends on the type and severity of the infection, so it should be decided by a doctor and never started without a prescription.
