Pharmacist tips for Bismuth subsalicylate (Pepto-Bismol)
You can take bismuth subsalicylate (Pepto-Bismol) with or without food. If it upsets your stomach, try taking the medication with food.
If you're taking bismuth subsalicylate (Pepto-Bismol) for diarrhea, make sure to drink plenty of fluids to stay hydrated. If you feel faint, lightheaded, or dizzy, seek medical help right away because these are signs of dehydration.
Check the ingredients of your other medications, including OTC medications, to see if they also contain salicylate. Taking too much bismuth subsalicylate (Pepto-Bismol) or other products containing salicylate, including aspirin or Salonpas pain relieving patches (camphor / menthol / methyl salicylate), can lead to symptoms of salicylate toxicity, including headache, dizziness, and ringing in the ear.
Tell your provider and pharmacist about all the medications you're taking, especially if you're taking a blood thinner or an NSAID like aspirin. Taking bismuth subsalicylate (Pepto-Bismol) with these medications raises your risk for bleeding and side effects. Additionally, don't use bismuth subsalicylate (Pepto-Bismol) if you have a history of a bleeding problem without asking your provider first.
Tell your provider if you notice a ringing in the ears or loss of hearing after you start using bismuth subsalicylate (Pepto-Bismol). If so, you'll probably need to stop taking bismuth subsalicylate (Pepto-Bismol). The ringing sound should go away and your hearing should return after you stop taking this medication.
You shouldn’t take bismuth subsalicylate (Pepto-Bismol) for more than 2 days. If you still have diarrhea or stomach problems after 2 days of taking the medication, talk with your provider. You'll need to be seen and examined for a more serious medical problem.

The oral suspension comes in two strengths, 525 mg/30 mL (e.g., Pepto Bismol, Kaopectate) and 525 mg/15 mL (e.g., Pepto Bismol Ultra, Kaopectate Max). Make sure to carefully double check the strength and recommended dose of your bismuth subsalicylate product carefully to avoid taking the wrong dose.
Shake well before each dose. Then, use a medication dose cup or an oral syringe to measure your dose.
