WHAT CLARITHROMYCIN SANDOZ IS USED FOR
Clarithromycin Sandoz is used to treat certain bacterial infections, including the following:
- respiratory tract infections (throat, airways and lungs)
- ear infections
- skin infections
- peptic ulcer
Clarithromycin Sandoz is also used to prevent a specific bacterial infection associated with HIV infection.
Clarithromycin Sandoz is an antibiotic that belongs to the group of medicines called macrolides. These medicines work by killing or stopping the growth of bacteria which cause infections. It contains the active ingredient clarithromycin.
Your doctor, however, may have prescribed Clarithromycin Sandoz for another purpose. Ask your doctor if you have any questions about why Clarithromycin Sandoz has been prescribed for you.
Clarithromycin Sandoz will not work against infections caused by viruses, such as colds or flu.
Clarithromycin Sandoz to treat peptic ulcer
Peptic ulcers are associated with an infection in the intestine and stomach by a bacteria called Helicobacter pylori (H. pylori). Nearly all patients with peptic ulcers are infected with this bacteria.
The H. pylori infection can be treated with a combination of Clarithromycin Sandoz (clarithromycin), another appropriate antibiotic and stomach acid control treatments.
However, the best combination of tablets to treat H. pylori infection is yet to be determined. Your doctor will determine the best combination for you.
If your symptoms return, consult your doctor. It is possible that Clarithromycin Sandoz may no longer be effective in treating the H. pylori infection and a different antibiotic may be needed.
There is no evidence that Clarithromycin Sandoz is addictive. Clarithromycin Sandoz is only available with a doctor's prescription.
