1. What is Clamoxyl and what is it used for

What is Clamoxyl

Clamoxyl is an antibiotic. The active ingredient is amoxicillin. This belongs to a group of medicines called "penicillins".

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

It is essential that you follow the instructions regarding dosage, administration interval, and treatment duration indicated by your doctor.

Do not store or reuse this medicine. If you have any leftover antibiotic after finishing the treatment, return it to the pharmacy for proper disposal. Do not throw medicines down the drain or in the trash.

What is Clamoxyl used for

Clamoxyl is used to treat infections caused by bacteria in different parts of the body. Clamoxyl can 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 components of this medicine (listed in section 6)
• if you have ever had an allergic reaction to any antibiotic. This can include a skin rash or swelling of the face or throat.

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

Warnings and precautions

Consult your doctor or pharmacist before starting to take Clamoxyl if:

• you have infectious mononucleosis (fever, sore throat, swollen glands, and extreme fatigue)
• 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 having:

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

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

Other medicines and Clamoxyl

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

• If you are taking allopurinol (used for gout) with Clamoxyl, you may be more likely to suffer 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 adjust the dose of Clamoxyl.
• If you are taking anticoagulants (such as warfarin), you may need more blood tests.
• If you are taking other antibiotics (such as tetracycline), Clamoxyl may be less effective.
• If you are taking methotrexate (a medicine used to treat cancer and severe psoriasis), penicillins can reduce the excretion of methotrexate and cause a potential increase in side effects.

Pregnancy, breastfeeding, and fertility

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

Driving and using machines

Clamoxyl may have side effects, and the symptoms (such as allergic reactions, dizziness, and convulsions) can make you unfit to drive.

Do not drive or operate machinery unless you feel well.

3. How to take Clamoxyl

Follow the administration instructions for this medicine exactly as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

• Swallow the capsules with water, without opening them.
• If you cannot swallow the capsule, tell your doctor, and they may prescribe a more suitable formulation for you. The capsules are not suitable for treating patients who cannot swallow capsules due to the risk of choking. Other formulations are available, depending on the dose, including oral formulations that can be used especially in patients who cannot swallow capsules.
• Space the doses evenly throughout the day, at least 4 hours apart.

The usual dose is:

Children under 40 kg of body weight

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

• The maximum recommended dose is 100 mg per kilogram of body weight per day.

Adults and children over 40 kg of body weight

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.

Kidney problems

If you have kidney problems, the 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, the signs may be stomach upset (nausea, vomiting, or diarrhea) or crystals in the urine, which can be observed as cloudy urine or problems urinating. Talk to your doctor as soon as possible. Bring the medicine to show it to the doctor.

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 forgotten doses.

How long to take Clamoxyl

• Continue taking Clamoxyl for the time your doctor has indicated, even if you feel better. You need to take all the doses to overcome the infection. If some bacteria survive, they can cause the infection to recur.
• Once you finish the treatment, if you still feel unwell, you should go back to see your doctor.

Thrush (a fungal infection of the moist parts of the body that can cause pain, itching, and white discharge) may appear if you take Clamoxyl for a long time. If this happens, consult your doctor.

If you take Clamoxyl for a long time, your doctor may perform additional tests to check that your kidneys, liver, and blood are functioning normally.

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