Amoxicillin is a penicillin antibiotic that is used to treat a variety of bacterial infections, such as ear, throat, chest, skin and urinary tract infections. It can also be used in combination with other medications to treat stomach ulcers caused by Helicobacter pylori bacteria. Amoxicillin is also known by its brand names Amoxil, Trimox and Moxatag.
But how much do you know about amoxicillin? How does it work, how should you use it, what are the possible side effects and interactions, and who should avoid it? In this blog post, we will answer some of the most frequently asked questions about amoxicillin and provide you with useful information to help you use this medication safely and effectively.
What is amoxicillin and how does it work?
Amoxicillin is a synthetic derivative of penicillin, a natural substance produced by certain molds that can kill or inhibit the growth of some bacteria. Amoxicillin was developed in the 1960s by a pharmaceutical company called Beecham. It was first approved by the Food and Drug Administration (FDA) in 1974 for the treatment of bacterial infections. Today, amoxicillin is available in various forms, such as capsules, tablets, chewable tablets, oral suspensions and injections. It can be bought with a prescription from a doctor or illegally from the street.
Amoxicillin works by interfering with the formation of the bacterial cell wall, which is essential for the survival and growth of the bacteria. By weakening the cell wall, amoxicillin causes the bacteria to burst and die. Amoxicillin is effective against a wide range of bacteria, such as Streptococcus, Staphylococcus, Haemophilus, Escherichia coli and Helicobacter pylori. However, some bacteria have developed resistance to amoxicillin and other penicillins by producing enzymes called beta-lactamases that can break down the antibiotic and make it ineffective.
How should you use amoxicillin?
The dose and frequency of amoxicillin depend on your age, weight, medical condition and response to treatment. You should always follow the instructions on the label or the prescription from your doctor. Do not take more than the recommended dose or for longer than advised.
The usual adult dose of amoxicillin for most infections is 250 to 500 mg three times a day or 500 to 875 mg twice a day as needed. The maximum daily dose is 6 g. For children aged 3 months to 12 years, the dose is based on their weight and is usually given as an oral suspension or a chewable tablet three times a day as needed. The maximum daily dose is 30 mg per kg of body weight.
You can take amoxicillin with or without food, but taking it with food may help prevent stomach upset. Do not crush, chew or break the capsules or tablets; swallow them whole with a glass of water. If you are using an oral suspension of amoxicillin, shake the bottle well before each use and measure the dose carefully with a dosing syringe or spoon. Do not use a household spoon, as you may not get the correct dose.
If you miss a dose of amoxicillin, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for the missed one.
If you take too much amoxicillin, seek medical attention immediately. Symptoms of overdose may include nausea, vomiting, diarrhea, stomach pain, skin rash, confusion, drowsiness and seizures.
What are the possible side effects and interactions of amoxicillin?
Amoxicillin is generally well tolerated by most people, but it can cause some side effects in some cases. The most common side effects are:
- Nausea, vomiting, diarrhea, stomach pain or indigestion
- Skin rash, itching or hives
- Headache, dizziness or fatigue
- Vaginal itching or discharge
- Thrush (a fungal infection of the mouth or vagina)
Most of these side effects are mild and temporary and can be reduced by taking amoxicillin with food or milk. However, some side effects can be serious and require medical attention. These include:
- Allergic reactions, such as swelling of the face, lips, tongue or throat, difficulty breathing or anaphylaxis (a severe and potentially life-threatening reaction that requires immediate medical attention)
- Severe skin reactions, such as Stevens-Johnson syndrome or toxic epidermal necrolysis (a rare but serious condition that causes blistering and peeling of the skin and mucous membranes)
- Liver problems, such as jaundice (yellowing of the skin or eyes), hepatitis (inflammation of the liver) or cholestatic jaundice (a type of liver damage caused by bile accumulation)
- Kidney problems, such as interstitial nephritis (inflammation of the kidney tissue) or crystalluria (formation of crystals in the urine)
- Blood problems, such as anemia (low red blood cell count), thrombocytopenia (low platelet count), leukopenia (low white blood cell count) or agranulocytosis (severe reduction of white blood cells)
- Nervous system problems, such as convulsions (seizures), peripheral neuropathy (damage to the nerves in the arms and legs) or encephalopathy (brain dysfunction)
If you experience any of these side effects while taking amoxicillin, stop taking it and contact your doctor right away.
Amoxicillin can also interact with other drugs and affect their effectiveness or increase their side effects. Some of the drugs that can interact with amoxicillin are:
- Allopurinol (a drug used to treat gout), which can increase the risk of skin rash when taken with amoxicillin
- Anticoagulants (blood thinners), such as warfarin or heparin, which can increase the risk of bleeding when taken with amoxicillin
- Birth control pills, which can become less effective when taken with amoxicillin
- Methotrexate (a drug used to treat cancer or rheumatoid arthritis), which can increase the levels and toxicity of methotrexate when taken with amoxicillin
- Probenecid (a drug used to treat gout), which can increase the levels and effects of amoxicillin when taken with amoxicillin
This is not a complete list of all the possible interactions of amoxicillin. Before taking amoxicillin, tell your doctor about all the medications, supplements and herbal products you are using or planning to use. Do not start, stop or change the dose of any drug without your doctor’s approval.
Who should avoid amoxicillin?
Amoxicillin is not suitable for everyone. Some people may have an allergy or intolerance to amoxicillin or any of its ingredients. Symptoms of an allergic reaction may include rash, itching, hives, swelling, difficulty breathing or anaphylaxis. If you have ever had an allergic reaction to amoxicillin or any other penicillin antibiotic, do not take amoxicillin.
Some medical conditions may also make amoxicillin unsafe or ineffective for you. You should not take amoxicillin if you have:
- A history of severe allergic reactions to any antibiotics
- A history of liver or kidney problems
- A history of mononucleosis (also called “mono”) or lymphatic leukemia
- A history of phenylketonuria (PKU), a genetic disorder that affects the metabolism of phenylalanine
You should also avoid amoxicillin if you are pregnant, planning to become pregnant or breastfeeding. Amoxicillin can harm the unborn baby or cause birth defects. It can also pass into breast milk and affect the nursing baby. Talk to your doctor before taking amoxicillin if you are pregnant, planning to become pregnant or breastfeeding.
Amoxicillin is not recommended for children under 3 months of age. The safety and effectiveness of amoxicillin in this age group have not been established. Amoxicillin can cause serious side effects in children, such as allergic reactions, skin reactions, liver problems, blood problems and nervous system problems.
How to use amoxicillin safely and effectively?
