Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about LPV. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking LPV against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.
What LPV is used for
LPV is an antibiotic that belongs to a group of medicines called penicillins. These antibiotics work by killing the bacteria that are causing your infection.
It is used to treat infections in different parts of the body caused by certain bacteria.
This medicine may also be used to prevent infections before, during and after surgery.
LPV will not work against infections caused by viruses, such as colds.
Ask your doctor if you have any questions about why LPV has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is available only with a doctor’s prescription.
There is no evidence that LPV is addictive.
