While you are using FLOPEN
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking FLOPEN.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
If you become pregnant while taking this medicine, tell your doctor immediately.
Tell your doctor immediately if the symptoms of your infection do not improve within a few days or if they become worse.
If you develop yellow eyes or skin (jaundice) whilst or soon after taking FLOPEN tell your doctor immediately. Do this even if it occurs several weeks after you have stopped taking FLOPEN. Jaundice may mean that you have a serious condition affecting your liver. You may need urgent medical attention.
If you get severe diarrhoea, tell your doctor or pharmacist immediately. Do this even if it occurs several weeks after you have stopped taking FLOPEN. Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without checking with your doctor.
If you get a sore white mouth or tongue, or get vaginal itching or discharge, tell your doctor. This may mean you have a fungal infection called thrush. Sometimes the use of FLOPEN allows fungi to grow and the above symptoms to occur. FLOPEN does not work against fungi.
If you get severe skin reactions with painful red areas, large blisters, peeling of skin layers; fever, chills, aching muscles, feeling unwell (signs of drug reaction with eosinophilia and systemic symptoms (DRESS) and acute generalised exanthematous pustulosis (AGEP), Stevens-Johnson Syndrome or toxic epidermal necrolysis). Stop taking this medicine immediately and tell your doctor.
If you are taking FLOPEN for a long time, visit your doctor regularly so that they can check on your progress.
You may need to have tests to check your liver and kidney function.
Things you must not do
Do not take any medicine for diarrhoea without first checking with your doctor or a pharmacist.
Do not take FLOPEN to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor. If you stop taking it suddenly, your condition may worsen.
Things to be careful of
Be careful driving or operating machinery until you know how FLOPEN affects you.
Things to be aware of
FLOPEN can cause jaundice (yellowing of skin and/or eyes) and severe liver disease. This is more frequent in older patients, particularly those over 55 years of age, and those who take the medicine for more than 14 days.
Immediately contact your doctor if you notice any yellowing of your eyes or skin.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking FLOPEN.
This medicine helps most people with a bacterial infection, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
- vomiting or an upset stomach
- a mild rash
- oral thrush - white, furry sore tongue and mouth
- vaginal thrush - sore and itchy vagina and/or discharge
If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
- watery and severe diarrhoea, which may also be bloody
- severe stomach cramps
- tiredness, headaches, being short of breath when exercising, dizziness and looking pale
- bleeding or bruising more easily than normal

After stopping FLOPEN
Tell your doctor if your skin and/or eyes have turned yellow (jaundice) whilst or soon after you finish taking FLOPEN.
Tell your doctor immediately if you notice any of the following side effects, even if they occur up to several weeks after finishing treatment with FLOPEN:
- watery and severe diarrhoea, which may also be bloody
- severe abdominal cramps or stomach cramps
- fever, in combination with one or both of the above
These are rare but serious side effects. FLOPEN can change the bacteria (which are normally present in the bowel and are harmless) to multiply and therefore can cause the above symptoms. You may need urgent medical attention.
After using FLOPEN
