Question:
My child caught rotavirus, and I was previously told there is no specific medicine for it. The diarrhea started yesterday evening (2 times), and today my child has had small amounts of watery diarrhea about 10 times. We are currently giving Bioflor (probiotics), but the doctor also prescribed Hidrasec (Racecadotril). I have always heard that antidiarrheal medications should not be taken during a viral infection. Is it safe to give this medication to my child?
Answer:
It is completely understandable to be worried when your child is having watery diarrhea 10 times a day due to rotavirus.
Understanding Antidiarrheals for Rotavirus
Standard antidiarrheals (like Loperamide) are generally not recommended for acute infectious diarrhea because they stop or slow down bowel movements, which can trap viruses and toxins inside the intestines.
Hidrasec (Racecadotril), however, works differently. It reduces intestinal fluid secretion without stopping bowel motility. Because it doesn't trap the virus in the gut, it is safe and commonly used for viral diarrhea like rotavirus.
Bioflor (probiotics) can safely be taken alongside this medication to help restore healthy gut bacteria.
What You Should Do Now
Take medications as prescribed: You can safely give Hidrasec and Bioflor according to your doctor's instructions.
Focus on hydration: This is the most important step. Offer an Oral Rehydration Solution (ORS, such as Pedialyte), clear broth, or water in small, frequent sips after every bout of diarrhea.
Monitor urine output: Keep a close eye on the frequency and color of your child's urine. Dark yellow urine or no urination for more than 8 hours are clear warning signs of dehydration.
Maintain nutrition: Continue feeding breastmilk or formula. If your child eats solid foods, offer easily digestible, bland options like rice porridge, bananas, or toast.
When to See a Doctor Immediately
Please seek urgent in-person medical evaluation if you notice any of the following red flags:
Signs of severe dehydration: dry lips and tongue, crying without tears, or no urine output for over 8 hours.
Stools containing blood or mucus.
Persistent high fever (38.5°C / 101.3°F or higher).
Severe abdominal pain.
Extreme lethargy, floppiness, or decreased responsiveness.
Rest assured that Hidrasec is an appropriate medication for rotavirus, so you can safely administer it while focusing primarily on keeping your child well-hydrated. If your child's symptoms persist, worsen, or if you observe any signs of dehydration, please visit your pediatrician for an in-person evaluation.
