Accidentally Tasted Benzoyl Peroxide Cream

2/15/2026, 5:00:19 AMMale25-34

Age: 21 years, Weight: 72 kg, Height: 175 cm. It's been half an hour since I wrote this. I just wrapped up my evening skincare regimen, during which I applied a 10% benzoyl peroxide treatment to my face. A few minutes later, while enjoying a leftover smoothie, I noticed a drop on my finger and instinctively licked it, only to realize moments later that it was benzoyl peroxide residue. I immediately recognized the taste, hesitated for a brief moment, and then hurried to rinse my mouth for about a minute. After rinsing, I consumed several glasses of warm water. At this point, I only feel a slight tingling and an extremely mild burning sensation on the tip of my tongue, as well as an unusual feeling at the back of my mouth. Given that I’ve eaten quite a bit today and have already gulped down around 750 ml of water since the incident, it's hard to discern if my mouth is overly salivating from the hydration or the benzoyl peroxide lick. What actions should I take next? My stomach feels quite full, and I haven't experienced any discomfort yet, as I did not ingest a significant quantity of the cream.

It's understandable to be concerned after accidentally tasting benzoyl peroxide cream, but it sounds like you've taken some good initial steps. Benzoyl peroxide is primarily a topical treatment and is not meant for ingestion. Here’s a concise overview of what you should know and do next.

Main Points:

  • Benzoyl peroxide can cause mild irritation but is generally not harmful in small amounts if ingested.
  • You've rinsed your mouth and consumed a good amount of water, which are positive actions.
  • Monitor your symptoms and know what to watch for.

Explanation:

Benzoyl peroxide is an acne treatment that can cause slight irritation of mucous membranes if ingested. The tingling and mild burning sensation you feel are common reactions and usually not serious, especially since it was a small amount. The fact that you rinsed your mouth and hydrated well helps mitigate potential discomfort.

Next Steps:

  1. Continue to Hydrate: Drink more water to help dilute any residual benzoyl peroxide, but avoid excessive ingestion if your stomach already feels full. Small sips are fine.

  2. Monitor Symptoms: Pay attention to your body over the next few hours. If the tingling or burning worsens, or if you develop nausea, difficulty swallowing, or any other concerning symptoms, that would be a sign to seek further assistance.

  3. Avoid Further Exposure: Refrain from consuming any more food or drink that might irritate your mouth for the rest of the evening (like acidic or spicy foods).

  4. Alleviate Discomfort: If you feel any residual irritation, consider consuming a smooth, soothing food (like yogurt) later to help calm your mouth, but wait until any immediate discomfort passes.

  5. Document the Incident: Keep track of your symptoms, timing, and any changes in how you feel over the next few hours.

It's good to remain calm and rational about the situation. If you have any changes in your condition or additional concerns, don’t hesitate to reach out for further advice.

Unusual Growth on My Toe: Seeking Insights

I’m a 17-year-old female experiencing a peculiar situation concerning my toes. It appears as though a second nail is developing over my existing toenails. After showering, this layer can be easily peeled off, but it consistently regrows, which has left me puzzled. There’s also a possibility that this might be linked to an incident from three years ago when I suffered from ingrown toenails on both of my big toes. While those eventually healed into fresh nails, I've now noticed this new growth, which seems to be continuously emerging atop my current nails. It's worth mentioning that this strange occurrence is localized to my big toes; no other toenails are affected. This has only become a concern recently, and I’ve only really started to pay attention to it in the past month. If anyone has insights or needs further information, I would be happy to provide more details.

Understanding Nutritional Care for Hospitalized Patients Who Can't Eat

A woman in her late 70s, specifically 77 years old, was previously in good health—actively engaging in everyday activities such as walking, talking, eating without assistance, and driving. However, she recently became ill due to pneumonia, leading to significant weakness and an inability to consume food orally. At her age, she does not have a feeding tube, and previous surgical options were deemed too risky. Currently, her only medications include those for managing blood pressure and a diuretic. After a few days of hospitalization, I find myself questioning the lack of nutritional support through intravenous means. Is it standard practice to provide nourishment via IV for patients in similar situations? A nurse mentioned that they typically administer nutrition through an IV tube, yet it seems she has only received intravenous fluids and no actual nutritional support for several days. This situation raises concerns, especially since she has no gastrointestinal complications and has been administered antibiotics, which have improved her respiratory function. Given that she has not had any food intake for an extended period, her weakness is becoming increasingly alarming. It makes me wonder if the healthcare team is overlooking the importance of nutrition in her recovery, especially when I know of many patients who have made remarkable recoveries with adequate nourishment. I approached the staff for clarification but felt my concerns were not thoroughly addressed; they only mentioned taking a wait-and-see approach regarding her treatment. Furthermore, the individual designated to make medical decisions on her behalf has expressed a desire for more aggressive treatment, as evidenced by the ongoing antibiotic prescriptions, indicating they do not want to abandon her care. I would appreciate further insights into the hospital's approach to managing nutritional needs in cases like this, as it seems she has been left without essential sustenance during a critical recovery period.

Frequent Illness in a Month: Seeking Answers

In the span of just one month, from January 5 until now, I have faced illness three times, and I currently find myself unwell once more. As a generally healthy young woman in my early twenties, I have been mindful of my wellness—my recent blood tests showed normal results, apart from a slight increase in white blood cells during my last examination. Despite my active lifestyle, nutritious diet, and lack of known medical conditions, I struggle to comprehend the reason behind this recurrent sickness. This ongoing situation has been significantly disruptive to my daily life. Could stress be a contributing factor? Am I possibly dealing with an autoimmune disorder?

Mixing DayQuil, NyQuil, and Tylenol in One Day: What Should I Do?

Hey there! I realize this might not be the smartest move, but I recently learned that combining these medications isn't advisable. My parents often take this combo when they’re unwell, but I’m uncertain if it’s safe for me. I would be grateful if someone could advise me on whether I need to contact poison control. A bit about me: I’m a teenager, standing at 5’3” and weighing 110 pounds. Today, I consumed a capful of liquid DayQuil around 10 AM, followed by NyQuil at approximately 8 PM, and throughout the day, I took between four to six doses of liquid Tylenol. As for how I’m feeling: So far, I haven’t experienced any severe symptoms, aside from some drowsiness likely from the NyQuil. My hands feel slightly tingly, although I can’t tell if that’s just out of anxiety. Additionally, there’s a bit of weakness in my foot, but that might just be in my head. Any insights would be helpful!

Concerns About Slightly Yellow Semen: Should I Be Alarmed?

M21 here, standing at 5 feet 6.5 inches and weighing in at 50 kilograms. I don’t indulge in smoking or drinking, and I've been noticing a yellowish tint in my semen for about a year now. The shade of yellow resembles that of urine, and I don't consume much water. Additionally, I lead a fairly sedentary lifestyle. On rare occasions, after masturbating, I experience a minor burning sensation. Could this be a cause for concern?
