Clinical Strategy Engine
Analyze your full medication stack

Pharmacists check for interactions. StackRx optimizes for absorption, timing, and your actual lab values. We do not flag what is dangerous — we tell you exactly when to take each medication and why.

Medications, supplements, and peptides in the StackRx database

Nobody has the full picture.

Your pharmacist checks for conflicts. Your pill organizer has slots for morning and night. But nobody tells you that your morning coffee is neutralizing your thyroid medication, or that your calcium supplement is blocking your antibiotic absorption. Nobody connects your declining kidney function to the three nephrotoxic medications you are taking simultaneously.

Without StackRx

Fragmented care, undetected risk

  • Multiple prescribers who do not communicate with each other
  • Calcium blocking thyroid absorption undetected for years
  • Nephrotoxic combinations tolerated until labs decline
  • Supplement-drug interactions outside pharmacy scope
  • Generic timing advice not calibrated to your biology
With StackRx

One strategy. Your full stack.

  • Every dose timed to the hour with clinical rationale
  • Absorption conflicts automatically separated
  • Lab values inform every timing and dosage decision
  • Rx, supplements, peptides, and OTC in one unified strategy
  • Plain-language explanation for every recommendation

If you are managing medications for an aging parent across multiple prescribers — PCP, cardiologist, endocrinologist, telehealth — you already know: nobody has the full picture. StackRx does.

If you are stacking peptides, nootropics, and supplements alongside your Rx — across multiple providers who do not communicate — you need interaction intelligence, not reminders.

📅 Sample Medication Strategy
Personalized for Mary, 72 · 22 lab values loaded
6:00 AM
Levothyroxine 75mcg
Take on empty stomach. Calcium, iron, and antacids block absorption if taken within 4 hours. TSH trending toward optimal range — maintain current timing discipline.
8:00 AM
Lisinopril 10mg + Metformin 500mg
Safe to combine. Take with breakfast to reduce metformin GI effects. eGFR 52 (Stage 3a CKD) — metformin dose reviewed, NSAIDs flagged as contraindicated, renally-cleared medications adjusted in this strategy.
12:00 PM
Vitamin D3 2000IU + Calcium 600mg
D3 enhances calcium absorption. Separated 6 hours from levothyroxine to prevent competition. Vitamin D deficient at last draw (18 ng/mL) — dosing strategy reflects repletion protocol.
9:00 PM
Atorvastatin 20mg
LDL 118 — timing aligned with peak hepatic cholesterol synthesis (9PM–midnight) for maximum statin efficacy. Evening dosing improves LDL reduction by 15% vs. morning equivalent.

Not a reminder app. Not an interaction checker. A strategy engine.

Most medication apps are digital alarm clocks. StackRx analyzes your bloodwork, cross-references your full medication stack, and determines whether your dosage timing is optimized for your body.

Precision absorption timing

Each medication has a distinct absorption profile. StackRx maps food requirements, pH sensitivity, and competing minerals to produce a timing strategy calibrated to the hour.

⚠️

Interaction analysis

Flags drug-drug and drug-supplement interactions — then separates conflicting doses by the clinically validated interval. Includes Rx, OTC, supplements, and peptides.

🧬

Lab-informed personalization

Upload your labs — PDF, photo, or email to your secure inbox. StackRx reads every value and calibrates your strategy to your actual kidney function, liver enzymes, and metabolic markers.

📈

Visual lab trends

Track how your strategy affects TSH, LDL, A1C, and kidney function over time. Personalized reference ranges — because a 75-year-old woman's normal creatinine is not the same as a 30-year-old man's.

💬

Plain-language rationale

Every recommendation includes a clinical explanation. Not "take at 6 AM" but "take levothyroxine 6 hours before calcium to prevent absorption competition at the intestinal transporter level."

📄

Clinical handoff

One-click PDF export for physicians, ER staff, pharmacists, or home-health providers. Your full medication strategy, timing rationale, interaction warnings, and lab context — on one page.

Three inputs. One precision strategy.

01

Enter your full stack

Rx, OTC, supplements, peptides, GLP-1s. Type the name and we pull pharmacokinetic data from our database of 500+ medications. Includes telehealth prescriptions and self-assembled supplement stacks.

02

Add your health profile

Age, sex, conditions, and daily routine. StackRx uses this data to personalize timing and surface risks specific to your physiology — not population-average defaults.

03

Upload your labs

Snap a photo. Upload a PDF. Forward to your secure lab inbox. Our AI reads every value and recalibrates your strategy around your actual numbers. eGFR, A1C, TSH, liver enzymes — all of it.

Reminder apps tell you when. StackRx tells you why.

A clinical strategy engine versus a digital alarm clock. The difference is the depth of analysis behind every recommendation.

Capability Reminder Apps StackRx
Timing guidance "Take your pill at 8 AM" "Take levothyroxine at 6 AM on empty stomach — 60 min before calcium to prevent absorption competition"
Interaction analysis Generic drug interaction lookup Lab-informed analysis calibrated to your kidney function, liver enzymes, and metabolic markers
Reference ranges Population-average thresholds Personalized ranges based on your age, sex, and clinical history
Lab integration None Upload labs → visual trends → trajectory alerts that flag decline before it becomes a crisis
Supplement + peptide support Limited or none Full stack — Rx, OTC, supplements, peptides, GLP-1s in one strategy
Clinical handoff None One-click PDF for physicians, ER staff, pharmacists, and caregivers

Complex medication situations require more than reminders.

Whether you are managing a parent's regimen across multiple specialists or assembling a precision wellness stack, StackRx provides the analysis layer that clinical care currently lacks.

🫀

Caregivers managing a parent's regimen

Your parent sees a PCP, a cardiologist, an endocrinologist, and a telehealth provider. None of them have visibility into the full prescription list. You do not either — until now. StackRx produces a single strategy you can share with every provider and print for the bedside.

💪

Self-assemblers and biohackers

BPC-157, semaglutide, creatine, magnesium, NAD+ precursors, vitamin D. Your stack is more complex than most clinical patients — and no single provider oversees it. StackRx is the safety net between you and the interactions nobody warned you about.

💊

Polypharmacy patients

Five or more medications daily places you at elevated risk for interactions your pharmacy software may not catch. StackRx cross-references your full list — including supplements and OTC — and flags the conflicts that clinical care missed.

🩹

Health-conscious adults

Even a simple stack — multivitamin, fish oil, magnesium, vitamin D — has timing implications that affect absorption and efficacy. StackRx ensures you get the full benefit from every medication you take.
