Dr. Bharat Joshi
I’m a periodontist and academician with a strong clinical and teaching background. Over the last 4 years and 8 months, I’ve been actively involved in dental education, guiding students at multiple levels including dental hygienist, BDS, and MDS programs. Currently, I serve as a Reader at MMCDSR in Ambala, Haryana—a role that allows me to merge my academic passion with hands-on experience. Clinically, I’ve been practicing dentistry for the past 12 years. From routine procedures like scaling and root planing to more advanced cases involving grafts, biopsies, and implant surgeries. Honestly, I still find joy in doing a simple RCT when it’s needed. It’s not just about the procedure but making sure the patient feels comfortable and safe. Academically, I have 26 research publications to my credit. I’m on the editorial boards of the Archives of Dental Research and Journal of Dental Research and Oral Health, and I’ve spent a lot of time reviewing manuscripts—from case reports to meta-analyses and even book reviews. I was honored to receive the “Best Editor” award by Innovative Publications, and Athena Publications recognized me as an “excellent reviewer,” which honestly came as a bit of a surprise! In 2025, I had the opportunity to present a guest lecture in Italy on traumatic oral lesions. Sharing my work and learning from peers globally has been incredibly fulfilling. Outside academics and clinics, I’ve also worked in the pharmaceutical sector as a Drug Safety Associate for about 3 years, focusing on pharmacovigilance. That role really sharpened my attention to detail and deepened my understanding of drug interactions and adverse effects. My goal is to keep learning, and give every patient and student my absolute best.

For a 3.5-month-old with persistent watery diarrhea following antibiotic use, it’s important to carefully assess the ongoing management and address the recent dosing error. First, always prioritize hydration. Since the baby is taking milk and ORS well, that’s a positive sign. Continue monitoring fluid intake closely. Regarding the medication issue, an accidentally higher dose of Metronidazole isn’t typically dangerous in a single instance, but you should be vigilant for signs of adverse effects like increased irritability or discomfort. Going forward, ensure you use the correct formulation—Flagyl 100mg/5ml—for the next dose, and give it at the prescribed frequency, twice daily at 3 ml per dose. It’s crucial not to administer another dose sooner to avoid exceeding the daily recommended dosage for your baby. Probiotics like Enterogermina can help restore gut flora disrupted by antibiotics. Maintain the current regimen but consult your pediatrician about the appropriate duration. Persistent diarrhea over 12 days warrants careful observation for signs of dehydration such as low urine output, dry mouth, or decreased activity. If any of these occur or diarrhea doesn’t improve, seek immediate medical attention. Be aware of red-flag symptoms like high fever, blood in stools, or refusal to feed, which would require urgent evaluation. Antibiotics can sometimes cause or exacerbate diarrhea, so reviewing the necessity for continued usage with a healthcare provider is advisable. Always discuss with your pediatrician before making changes in medication to ensure treatment is appropriately tailored to your child’s needs.
