EENT: tinnitus, tongue discoloration
GI: nausea, vomiting, diarrhea, constipation, gray-black stools, fecal impaction
Other: salicylate toxicity
Drug-drug.Aspirin, other salicylates: salicylate toxicity
Corticosteroids, probenecid (large doses),
sulfinpyrazone: decreased bismuth efficacy
Enoxacin: decreased enoxacin bioavailability
Methotrexate: increased risk of bismuth toxicity
Tetracycline: decreased tetracycline absorption
Drug-diagnostic tests.Radiologic GI tract examination: test interference
• Monitor fluid intake and electrolyte levels.
• Monitor stool frequency and appearance.
• Assess infants and debilitated patients for fecal impaction.
• Instruct patient to chew tablets or dissolve them in mouth before swallowing.
• Inform patient that drug may turn stools gray-black temporarily.
• Tell patient to notify prescriber if he has diarrhea with fever for more than 48 hours.

Adverse Reactions/Side Effects
- gray-black stools
- impaction (infants, debilitated patients)
Drug-Drug interactionIf taken with aspirin, may ↑ the risk of salicylate toxicity.May ↓ absorption of tetracycline or fluoroquinolones (separate administration by 2–4 hr).May ↓ effectiveness of probenecid (large doses).
Availability (generic available)
- Diarrhea: Assess the frequency and consistency of stools, presence of nausea and indigestion, and bowel sounds before and during therapy.
- Assess fluid and electrolyte balance and skin turgor for dehydration if diarrhea is prolonged.
- Ulcers: Assess for epigastric or abdominal pain and frank or occult blood in the stool, emesis, or gastric aspirate.
- Lab Test Considerations: Chronic high doses may cause falsely ↑ uric acid levels with colorimetric assay.
- May interfere with radiologic examination of the GI tract.
- May cause abnormal results with alkaline phosphatase, AST, and ALT tests.
- May cause ↓ potassium levels and serum T3 and T4 concentrations.
- Large doses of salicylates may also cause prolonged prothrombin time (PT).
- For additional lab test considerations related to salicylate content, see salicylates monograph.
