Metronidazole for Treating SIBO
I have been given a prescription for Metronidazole, taking 500mg three times daily over a span of 14 days, aimed at addressing methane-dominant small intestinal bacterial overgrowth (SIBO). Initially, I was supposed to receive Rifaximin for my SIBO treatment; however, it turns out my insurance will not cover that medication. My concern lies in whether this prescribed dosage is considered safe. I've come across some troubling information regarding potential side effects and a possible risk of dental health issues associated with this medication. To provide some background, I am a 56-year-old female, weighing 130 pounds, and currently, I have no known health issues apart from SIBO.

Metronidazole can be an effective alternative for treating methane-dominant small intestinal bacterial overgrowth (SIBO), particularly if Rifaximin is not an option due to insurance coverage. Your prescribed dosage of 500 mg three times daily for 14 days is generally considered safe for adults and is within established guidelines for treating bacterial infections.
Understanding the Medication
Metronidazole works by killing bacteria and protozoa. It is commonly used for various infections and can also help manage SIBO. While effectiveness is key, it’s also important to be aware of potential side effects. Common side effects may include nausea, headaches, and a metallic taste. There are also rare severe side effects, including potential impacts on dental health, as metronidazole can affect the oral microbiome.
Next Steps for Safety and Effectiveness
Here are actionable steps you can take while on Metronidazole:
-
Monitor Side Effects:
- Keep track of any side effects you experience. If you notice severe reactions like persistent nausea, vomiting, rash, or unusual headaches, note them quickly.
-
Hydrate and Maintain Nutrition:
- Drink plenty of water and eat a balanced diet. This will help mitigate any gastrointestinal discomfort and ensure your body functions well while on the medication.
-
Oral Care:
- Maintain good oral hygiene by brushing your teeth regularly and using mouthwash to minimize any potential effects on dental health.
-
Discuss Concerns:
- If you have specific worries about the side effects or if you experience any unacceptable symptoms, consider discussing these with your healthcare provider. They may offer solutions or alternative treatments.
-
Follow-Up Monitoring:
- Plan to follow up with your healthcare provider after completing the course to evaluate how effective the treatment has been and to check on any lingering symptoms associated with SIBO.
Reassurance
It's understandable to have concerns about a new medication, but many people tolerate Metronidazole well without severe issues. Listening to your body and maintaining open communication with your healthcare team is vital. If you have any other questions, feel free to reach out!

Light Pink Discharge After Urination
Just yesterday, after using the restroom, I spotted a faint pink hue on the toilet paper. Initially, I thought it might indicate the start of my menstrual cycle, especially since I didn’t have my period last month during the last week of January. However, today I haven't noticed any blood, and I don't anticipate any appearing this week or even the next. Additionally, I observed small traces of blood in my urine during the week my period was supposed to arrive. While I do experience some hormonal symptoms, I’m uncertain about their meaning. Thankfully, I haven’t felt any burning sensations, but I find myself feeling confused and, to be honest, a bit anxious about the situation. I maintain an average weight, I’m not on any medications, and I do not smoke.
Worsening Memory Problems Over Time
Age: 25 Weight: 175 lbs Current Medications: Modafinil (200mg); Lexapro (10 mg); Lamotrigine (100mg in the morning + 100 mg in the evening); Cyproheptadine (4 mg); Vraylar (1.5 mg) Supplements: Iron; Vitamin B12; Vitamin D; Salt tablets Health Background: Long-standing, stubborn migraines (resolved as of May 2025, originally began in April 2016); Depression (currently very stable); Attention Deficit Disorder (ADD) (experimented with various stimulants with no improvement in memory); Chronic fatigue syndrome (developed a few years after memory problems began). I possess a documented medical history concerning my memory challenges. Around 2012, I underwent neurological evaluations that included an IQ assessment. The clinician indicated that my memory performance was particularly low, affecting my overall IQ representation, while I scored at or above average in most other areas. In approximately 2017, a neurologist referred me for a neuropsychological evaluation. Unfortunately, the results were deemed "inconclusive" due to inconsistent findings, with the provider stating my memory levels mirrored the previously reported low scores. Fast forward to 2023, when I underwent another neuropsych evaluation, which indicated my working memory was significantly below the average range. The clinician expressed uncertainty regarding effective treatment options for my memory issues, suggesting avenues such as ADHD medications, stress management, enhancing sleep quality, and mental health support—areas which I have pursued or tried to improve. Here is a summary of the strategies and treatments I've explored: - **Sleep Study**: Diagnosed with mild sleep apnea when lying on my back, although I typically sleep in other positions. - **Antidepressants**: Tried various types repeatedly, yet without noticing any significant changes. - **Occupational Therapy**: Participated but found it more stressful than beneficial. - **Speech Therapy**: Benefitted somewhat, yet it didn't meet my expectations, though I continue to use some of the techniques learned. - **Digital Notes**: Attempted to record important information on my phone, but due to many lists, vital entries often get lost. - **Memantine**: Prescribed by my neurologist as a last resort, based on its reported effectiveness in elderly patients for pain management; however, I did not observe any memory improvements while on this medication. - **Nutritional Supplements**: Regularly take Vitamin B complex, fish oil, flaxseed oil, and various other potential memory enhancers. Additionally, family history reveals that my brother, sister, and paternal grandmother have also faced memory-related issues throughout their lives. Unfortunately, several neurologists have declined to treat me, citing my youth and existing diagnoses of depression and ADD as indicators of instability rather than addressing my memory concerns. Moreover, I am anxious that my past struggles with chronic pain could have exacerbated my memory problems. Any insights or suggestions to tackle these ongoing challenges would be greatly appreciated.
Seeking Clarity on Brain MRI Results
I’m a 36-year-old man experiencing occasional headaches, and I have no additional health concerns. I take Lexapro for anxiety and Ativan as needed. Earlier this week, I underwent a non-contrast MRI scan of my brain, and I have received the following report: **REASON FOR EXAMINATION:** Periodic headaches described as dull in nature. **COMPARISON:** None available. **TECHNIQUE USED:** The imaging included sagittal T1, axial FLAIR, axial T2-weighted, diffusion-weighted, and coronal gradient-echo sequences of the brain. **RESULTS:** The size of the ventricles and sulci appears to be normal. The position of the cerebellar tonsils is also within normal limits. Notably, a bilobed, septated lesion measuring 18 x 10 mm is located in the right parietal cortex, associated with some underlying edema or gliotic changes and cortical expansion. The pituitary gland size is normal. There are no signs of intracranial bleeding or any indications of recent infarcts in the cerebral regions, brainstem, or cerebellum. No abnormalities were detected on diffusion-weighted imaging. Additionally, there are no signal changes that would imply a demyelinating condition, such as multiple sclerosis. There are no fluid collections outside of the brain or subdural hematomas noted. Major blood vessels are patent, as indicated by the flow voids. The paranasal sinuses and mastoid air cells appear clear, although there is mild mucosal thickening in the left anterior ethmoidal air cells. **SUMMARY:** The findings suggest an 18 x 10 mm intra-axial cystic lesion in the right parietal lobe, accompanied by mild underlying edema or gliotic changes. This could possibly be an atypical manifestation of enlarged perivascular spaces or a benign cystic structure. Further evaluation with postcontrast imaging is advised. The overall conclusion of the MRI is otherwise normal. I’m feeling really anxious about these findings. Can anyone help me understand what this might mean?
Unexplained Bruising and Intense Itching
Hello, I’m a 20-year-old female, standing at 5 feet 2 inches and weighing 135 pounds. Recently, I have been experiencing intense itching that has resulted in significant bruising on my skin. Currently, I’m on several medications including spironolactone (which I haven’t taken for the last two weeks), Effexor, Aimovig, Wegovy, and Linzess. I do not use tobacco or consume alcohol. Apart from experiencing a generally sluggish digestive system, I have no pre-existing health issues. However, my family medical history indicates occurrences of Multiple Sclerosis, Hashimoto’s disease, diabetes, and eczema. The itching has become severe, leading to large bruises forming on my body. I consulted a virtual urgent care service, which advised me to visit the emergency room to check for potential blood clots or internal bleeding. Upon arriving at the ER, I underwent various tests, and I noticed that my resting heart rate has been notably elevated between 120 and 140 beats per minute, though I am uncertain if this is a new development. Eventually, I was discharged without any conclusive information, except with the advice to refrain from scratching. I have shared images of the tests conducted during my visit.
Concerns About Abdominal Distension
Hello, I'm a 25-year-old female, weighing approximately 51 kilograms and standing at 155 centimeters tall. I have established allergies to Prospan and certain vitamins, which I actively avoid in my diet. My daily caloric intake is around 2250 kcal, and I supplement my nutrition with B complex vitamins, omega-3 fatty acids, and vitamins C and D. I do not have any identified food allergies that I know of. I maintain a workout regimen that spans four days each week, followed by a day of rest. However, I’ve noticed a consistent issue where my lower abdomen noticeably swells after each meal. To me, it resembles the growth associated with early to mid-pregnancy, and it seems to occur only in that specific area. This situation is worrying me, and I would greatly appreciate any advice you might be able to provide. I am contemplating visiting a gastroenterologist soon, but I thought I’d ask for perspectives here as well, just in case. Thank you for any insights you can share. Best, 'Not Pregnant, Just Full' girl
