According to the National Health Service of Great Britain, it is all right to drink alcohol while taking co-amoxiclav. In addition, co-amoxiclav has no known food interactions. The drug, which combines amoxicillin trihydrate and clavulanic acid, is an antibiotic.
The National Health Service indicates that people with certain conditions should not use co-amoxiclav. People with allergies to antibiotics such as penicillin should avoid it, as should anyone with liver or kidney problems. Pregnant women should discuss with their doctors whether to take the drug. In addition, anyone who drives or operates heavy machinery should use caution if the drug is prescribed, because it sometimes interferes with safe maneuvering.
