5 Conservation of Medoclav
Medoclav is an antibiotic that eliminates the bacteria that cause infections. It contains two different active substances called amoxicillin and clavulanic acid. Amoxicillin belongs to the group of medications known as "penicillins" which can sometimes lose their effectiveness (become inactivated). The other component (clavulanic acid) prevents this from happening.
Antibiotics are used to treat bacterial infections and are not effective against viral infections such as the flu or the common cold.
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 medication. If you have any leftover antibiotic after completing the treatment, return it to the pharmacy for proper disposal. Do not throw away medications down the drain or in the trash.

Medical Advice/Education
Antibiotics are used to treat bacterial infections. They are not effective against viral infections.
Sometimes a bacterial infection does not respond to antibiotic treatment. One of the most common reasons for this is that the bacteria causing the infection are resistant to the antibiotic being taken. This means that the bacteria can survive or grow despite the antibiotic.
Bacteria can become resistant to antibiotics for many reasons. Using antibiotics properly can reduce the chances of bacteria becoming resistant to them.
When your doctor prescribes an antibiotic, it is only for the course of your illness. Paying attention to the following advice will help you prevent the appearance of resistant bacteria that can make the antibiotic ineffective.
If you still have antibiotic left after completing the treatment, return all unused medication to your pharmacy to ensure that disposal requirements are met.
The average price of MEDOCLAV 875 mg/125 mg FILM-COATED TABLETS in October, 2025 is around 6.81 EUR. Prices may vary depending on the region, pharmacy, and whether a prescription is required. Always check with a local pharmacy or online source for the most accurate information.
