1. What Clamoxyl is and what it is used for

What Clamoxyl is

Clamoxyl is an antibiotic. The active substance is amoxicillin. This belongs to a group of medicines known as "penicillins".

Antibiotics are used to treat bacterial infections and are not effective against viral infections such as flu or the common cold.

It is important that you follow the instructions regarding dose, dosing interval, and duration of treatment as given by your doctor.

Do not store or reuse this medicine. If you have any antibiotic left over after completing treatment, return it to the pharmacy for proper disposal. Medicines must not be disposed of via wastewater or household waste.

What Clamoxyl is used for

Clamoxyl is used to treat bacterial infections in different parts of the body. Clamoxyl may also be used in combination with other medicines to treat stomach ulcers.

2. What you need to know before taking Clamoxyl

Do not take Clamoxyl

  • if you are allergic to amoxicillin, penicillin, or any of the other ingredients of this medicine (listed in section 6)
  • if you have ever had an allergic reaction to any antibiotic. This may include a skin rash or swelling of the face or throat.

Do not take Clamoxyl if any of the above apply to you. If you are unsure, consult your doctor or pharmacist before taking Clamoxyl.

Warnings and precautions

Talk to your doctor or pharmacist before starting Clamoxyl if:

  • you have infectious mononucleosis (fever, sore throat, swollen glands, and extreme tiredness)
  • you have kidney problems
  • you do not urinate regularly.

If you are unsure whether any of the above symptoms apply to you, consult your doctor or pharmacist before taking Clamoxyl.

Blood and urine tests

If you are undergoing:

  • urine tests (urine glucose) or blood tests for liver function
  • estriol tests (used during pregnancy to check whether the baby is developing normally),

inform your doctor or pharmacist that you are taking Clamoxyl. This is because Clamoxyl may alter the results of these types of tests.

Other medicines and Clamoxyl

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

  • If you are taking allopurinol (used for gout) with Clamoxyl, you may be more likely to experience a skin allergic reaction.
  • If you are taking probenecid (used to treat gout), it may reduce the excretion of amoxicillin and is not recommended. Your doctor may need to adjust your Clamoxyl dose.
  • If you are taking anticoagulants (such as warfarin), you may need more frequent blood tests.
  • If you are taking other antibiotics (such as tetracycline), Clamoxyl may be less effective.
  • If you are taking metotrexate (a medicine used to treat cancer and severe psoriasis), penicillins may reduce the excretion of methotrexate and potentially increase adverse effects.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

Driving and using machines

Clamoxyl may cause adverse effects, and symptoms (such as allergic reactions, dizziness, and seizures) may impair your ability to drive.

Do not drive or operate machinery unless you feel well.

3. How to take Clamoxyl

Follow exactly the instructions for using this medicine as given by your doctor or pharmacist. If you are unsure, consult your doctor or pharmacist again.

  • Swallow the capsules with water, without opening them.
  • If you cannot swallow the capsule, inform your doctor, who may prescribe another formulation more suitable for you. Capsules are not suitable for treating patients who cannot swallow capsules due to the risk of choking. Alternative formulations are available, depending on the dose, including oral formulations that can be used specifically in patients who cannot swallow capsules.
  • Space the doses evenly throughout the day, with at least 4 hours between doses.

The usual dose is:

Children weighing less than 40 kg

All doses are calculated based on the child's body weight in kilograms.

  • Your doctor will tell you how much Clamoxyl to give your baby or child.
  • The usual dose is 40 mg to 90 mg per kilogram of body weight per day, given in two or three divided doses.
  • The maximum recommended dose is 100 mg per kilogram of body weight per day.

Adults and children weighing 40 kg or more

The usual dose of Clamoxyl is 250 mg to 500 mg three times a day or 750 mg to 1 g every 12 hours, depending on the severity and type of infection.

  • Severe infections: 750 mg to 1 g three times a day.
  • Urinary tract infection: 3 g twice a day for one day.
  • Lyme disease (an infection transmitted by parasites called ticks): isolated erythema migrans (early stages – circular pink or red rash): 4 g per day; systemic manifestations (late stages – more severe symptoms or when the disease spreads through the body): up to 6 g per day.
  • Stomach ulcers: 750 mg or 1 g twice a day for 7 days, together with other antibiotics and medications for treating stomach ulcers.
  • To prevent heart infection during surgery: the dose will vary depending on the type of surgery. Other medications may be given at the same time. Your doctor, pharmacist, or nurse can provide further details.
  • The maximum recommended daily dose is 6 g per day.

Kidney problems

If you have kidney problems, your dose may be lower than the usual dose.

If you take more Clamoxyl than you should

If you have taken more Clamoxyl than you should, symptoms may include stomach upset (nausea, vomiting, or diarrhea) or crystals in the urine, which may appear as cloudy urine or difficulty urinating. Contact your doctor as soon as possible. Take the medicine with you so you can show it to the doctor.

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately, or call the Toxicology Information Service at 91 562 04 20, stating the medicine and the amount ingested.

If you forget to take Clamoxyl

  • If you forget to take a dose, take it as soon as you remember.
  • Do not take the next dose too soon; wait at least 4 hours before taking the next dose.
  • Do not take a double dose to make up for a missed dose.

How long you should take Clamoxyl

  • Continue taking Clamoxyl for the length of time prescribed by your doctor, even if you start to feel better. You need to take all the doses to completely eliminate the infection. If some bacteria survive, the infection may return.
  • If you still feel unwell after completing the treatment, you should see your doctor again.

Prolonged use of Clamoxyl may lead to candidiasis (a fungal infection in moist areas of the body that may cause pain, itching, and white discharge). If this occurs, consult your doctor.

If you take Clamoxyl for a prolonged period, your doctor may perform additional blood tests to monitor the normal function of your kidneys, liver, and blood.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
