⚠️ Critical limitation — please read
Pillara is an informational tool only. It does not provide medical advice, medical diagnosis, medical treatment, or medical recommendations. Information provided by Pillara — whether from the AI assistant, the drug interaction checker, or any other feature — is not a substitute for professional medical advice from a licensed healthcare provider.
Always consult a qualified doctor, pharmacist, or other licensed healthcare professional before making any decision about your medications. Never delay seeking professional medical advice because of something you read on Pillara. Never disregard professional medical advice because of something Pillara told you.
Pillara's AI assistant may sometimes produce incorrect, incomplete, or outdated information. Drug interactions are complex. The absence of a warning from Pillara does not mean a combination is safe. The presence of a warning does not mean you should stop your medication without speaking to your doctor first.
This section describes what the Service does technically, so you understand its capabilities and limitations:
3.1 Drug Interaction Checker
When you submit a list of medications, Pillara searches a database of 541+ drug knowledge chunks derived from FDA drug label data and RxNorm (US National Library of Medicine) data. It uses hybrid semantic and keyword search, followed by a cross-encoder re-ranking model, to find the most relevant information. A confidence gate (threshold: 0.75) ensures that if relevant verified data is not found at sufficient confidence, the system returns a safe "insufficient data" response rather than guessing.
Limitation: Our drug knowledge database primarily covers US FDA-approved drugs. Coverage of Nigerian-specific brand names and locally manufactured generics may be incomplete. Drug interactions not well-documented in FDA data may not be detected.
3.2 Allergy Cross-Reactivity Detection
Pillara checks your stated allergies against a three-layer system: drug class membership (e.g. penicillins), molecular family relationships (e.g. beta-lactams), and known cross-reactive compounds. This runs deterministically — without AI — before the interaction check.
Limitation: Allergy cross-reactivity is medically complex and individual. Our detection covers documented cross-reactivity patterns but cannot account for individual patient sensitivity, undocumented allergies, or novel drug combinations.
3.3 AI Medication Assistant
The AI assistant answers medication-related questions using a retrieval-augmented generation (RAG) pipeline. Responses are grounded in verified clinical data retrieved from our database. The system uses multiple AI providers (currently Groq and Google Gemini) as fallbacks for reliability. Off-topic questions (unrelated to medications) are rejected before reaching the AI.
Limitation: AI-generated responses may contain errors. Drug names and questions are sent to third-party AI providers (Groq, Google Gemini) for processing. Your name, email, and account identity are not sent to AI providers, but drug names and your questions are. AI providers' own terms apply to this data.
3.4 Multi-Patient Profile Sharing
You can create profiles for patients you manage and invite other users to access those profiles. Roles are: owner (full control), caregiver (can view and add medications), viewer (read only). Access can be revoked at any time by the profile owner.
Limitation: You are responsible for ensuring that anyone you invite to access a profile has appropriate authorization from the patient. Pillara does not verify caregiver-patient relationships.
3.5 Medication Reminders
You can configure email reminders for medications. Reminders are processed by an asynchronous background worker. In the event of a technical failure, Pillara runs a missed reminder recovery job every 10 minutes. However, we cannot guarantee 100% reminder delivery.
Limitation: Pillara reminders are not a substitute for proper medication management. Do not rely solely on Pillara reminders for critical medications. Email delivery depends on third-party services and may be subject to spam filtering.
You are responsible for:
You may not share your account with others. You may not use Pillara to manage medications for a patient without appropriate authorization from that patient or their legal guardian.
