Klacid 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.
Klacid will not work against infections caused by viruses, such as colds or flu.
Klacid is available only with a doctor's prescription.
Klacid 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 Klacid (clarithromycin) and other 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 Klacid may no longer be effective in killing the H. pylori infection and a different antibiotic may be needed.
