What CLARITHROMYCIN AN is used for
CLARITHROMYCIN AN is used to treat certain bacterial infections, including the following:
- respiratory tract infections
- skin infections
- peptic ulcer
CLARITHROMYCIN AN is also used to prevent a specific bacterial infection associated with HIV infection.
Your doctor, however, may have prescribed CLARITHROMYCIN AN for another purpose. Ask your doctor if you have any questions about why CLARITHROMYCIN AN has been prescribed for you.
CLARITHROMYCIN AN 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.
CLARITHROMYCIN AN will not work against infections caused by viruses, such as colds or flu.
CLARITHROMYCIN AN is available only with a doctor’s prescription.
CLARITHROMYCIN AN 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 AN (clarithromycin), another antibiotic (amoxycillin) and another medicine called omeprazole (used to control the acidity of the stomach).
However, the best combination of tablets to treat Helicobacter 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 AN may no longer be effective in killing the Helicobacter pylori infection and a different antibiotic may be needed.
