1. What Co-amoxiclav Bluefish is and what it is used for
Co-amoxiclav Bluefish is an antibiotic with bactericidal activity against bacteria causing infections. Co-amoxiclav Bluefish contains two different active substances: amoxicillin and clavulanic acid. Amoxicillin belongs to a group of medicines called "penicillins", whose activity may sometimes be inhibited (inactivated). The second active ingredient (clavulanic acid) counteracts this inactivation.
Co-amoxiclav Bluefish is used in adults and children to treat the following infections:
- Middle ear and sinus infections
- Respiratory tract infections
- Urinary tract infections
- Skin and soft tissue infections, including dental infections
- Bone and joint infections.
2. Important information before using Co-amoxiclav Bluefish
When not to use Co-amoxiclav Bluefish
- If the patient is allergic to amoxicillin, clavulanic acid, or any of the other ingredients of this medicine (listed in section 6).
- If the patient has ever had severe allergic reactions (hypersensitivity) to any other antibiotic. These may include skin rash or swelling of the face or neck area.
- If the patient has ever had liver function disorders or jaundice (yellowing of the skin) associated with the use of an antibiotic.
If any of the above situations apply, the patient should not take Co-amoxiclav Bluefish.

Conditions to be aware of
Treatment with Co-amoxiclav Bluefish may worsen certain diseases or cause serious adverse effects, including allergic reactions, seizures, and colitis. It is important to monitor whether the patient develops specific symptoms during treatment with Co-amoxiclav Bluefish to reduce the risk of complications. See "Conditions to be aware of" in section 4.
Blood and urine tests
If the patient is due to have blood tests (such as red blood cell count or liver function tests) or urine tests (for glucose), inform the doctor or nurse that the patient is taking Co-amoxiclav Bluefish. Co-amoxiclav Bluefish may affect the results of such tests.

Inform the doctor about all medicines currently taken or recently taken, as well as any medicines the patient plans to take.
If the patient is taking allopurinol (used for gout) at the same time as Co-amoxiclav Bluefish, skin allergic reactions may be more likely.
If the patient is taking probenecid (used for gout), the doctor may decide to adjust the dose of Co-amoxiclav Bluefish.
If the patient is taking anticoagulant medicines (such as warfarin) together with Co-amoxiclav Bluefish, additional blood tests may be necessary.
