There is neither a pharmacologic basis nor data suggesting an increased toxicity of the combination compared to individual components.
Bismuth Subcitrate Potassium:
The optimal treatment of bismuth overdosage is unknown. Gastric lavage, purgation, and hydration should be considered, even if the patient presents late, as bismuth may be absorbed from the colon. Chelating agents may be effective in the early stages following ingestion.
Haemodialysis may be necessary but whether this hastens tissue clearance is uncertain.
Metronidazole:
Massive ingestion may produce vomiting, ataxia and slight disorientation. 4 g every other day. There is no specific antidote for metronidazole overdose. Management of the patient should consist of symptomatic and supportive therapy. Metronidazole is dialyzable.
Give ipecac syrup or perform gastric lavage. Activated charcoal combined with a cathartic may also be used.
Tetracycline:
The acute toxicity of tetracycline in overdose is not well established in the literature. Therapeutic and overdose quantities of tetracycline can cause gastrointestinal symptoms such as nausea, vomiting, diarrhea, esophagitis or esophageal ulceration.
Pylera® Page 6 of 35 Hypersensitivity reactions including anaphylaxis may also occur. There is no specific antidote for tetracycline overdose. Management of the patient should consist of symptomatic and supportive therapy. Tetracycline is not dialyzable.
Dilute well with water or milk due to the possibility of esophageal ulceration. g. calcium carbonate or lactate, milk of magnesia, aluminum hydroxide). Measures to reduce absorption such as induction of emesis or use of cathartic may be beneficial in certain patients.

Stool darkening should not be confused with melaena. Metronidazole Known or previously unrecognized candidiasis may present more prominent symptoms during therapy with metronidazole and requires treatment with a candicidal agent. Tetracycline Hydrochloride THE USE OF DRUGS OF THE TETRACYCLINE CLASS DURING TOOTH DEVELOPMENT (LAST HALF OF PREGNANCY, INFANCY, AND CHILDHOOD TO THE AGE OF 8 YEARS) MAY CAUSE PERMANENT DISCOLOURATION OF THE TEETH (YELLOW-GRAY-BROWN).
