📋 A Friendly Reminder About Our Patient Portal 📋
We love that so many of our families use the patient portal to stay connected with us! It's a great tool for quick questions and accessing your child's health records.
However, there are some requests that we may not be able to fully address through a portal message alone. These include:
🔹 Requests for new prescriptions or medication changes
🔹 Sending photos of rashes, injuries, or other symptoms for diagnosis
Why?
Because your child's safety comes first. Prescribing medication and evaluating skin changes, injuries, or other concerns often require a hands-on examination. Without seeing your child in person, we may not have the full picture needed to make the safest and most accurate medical decisions.
✅ What the portal IS great for:
• Requesting prescription refills for current medications
• Asking general, non-urgent questions
• Reviewing test results and visit summaries
If you send a portal message with a prescription request or a photo asking for a diagnosis, our team may ask you to schedule an office visit so we can properly evaluate your child. This isn't to create extra steps — it's to make sure your child gets the best care possible.
Thank you for understanding, and as always, we're here for your family! 💙
📞 For urgent concerns, please call our office directly. For emergencies, call 911 or go to your nearest emergency room.
