Take this medicine exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
Helidac® comes with patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions.
Each day's therapy is packaged in a blister card that contains 8 chewable tablets of bismuth subsalicylate, 4 tablets of metronidazole, and 4 capsules of tetracycline.
Pay attention to how to take each medicine. Completely chew and swallow 2 bismuth tablets. Swallow the metronidazole tablets and tetracycline capsules with a full glass of water. This will help prevent irritation of the esophagus (tube between the throat and stomach). Do not chew, crush, or break the metronidazole tablets and tetracycline capsules.
Your doctor will also prescribe another medicine, a histamine H2 receptor antagonist, which will come with its own directions and must be taken along with this combination of medicines.
Avoid taking milk, dairy products, antacids containing aluminum, calcium, or magnesium (e.g., Maalox®, Tums®), or supplements containing iron, zinc, or sodium bicarbonate. This may keep tetracycline from working properly.
To help clear up your infection completely, keep using this medicine for the full time of treatment, even if you begin to feel better after a few days. If you stop taking this medicine too soon, your symptoms may return.
