The pharmacist who never clocks off

Is it safe to take them together?

You shouldn't need a pharmacy visit to find out. Bolus checks every medicine you take against every other one, plus your food, supplements and conditions, and explains what to watch for in plain language. All on your phone.

How it works

Three taps from worry to an answer.

No account, no setup, nothing to upload. Add what you take and Bolus does the rest, on your phone.

Step 1

Add your medicines

Scan a label or search by name, prescriptions and supplements alike. Up to three medications are free, forever.

Step 2

Bolus checks, on-device

Every pair, plus food, supplements and your conditions, cross-checked against a cited safety database. Nothing leaves your phone.

Step 3

Know what to watch for

Plain-language alerts with the mechanism and the evidence, a safer daily schedule, and a report you can hand your doctor.

Why it matters

Five bottles. Or fifteen.

The risk is rarely one dangerous pair. It's the quiet build-up across a whole regimen, the kind a busy appointment can miss. Bolus reads the whole picture and does the maths.

What Bolus does

A pharmacist's counsel, in your pocket.

Every capability below runs on the device. Safety is never behind the paywall.

Interaction checks

Drug against drug, food, supplement, alcohol and your conditions, cross-checked in seconds.

Plain-language alerts

Ranked by what actually matters, written like a person, never a leaflet.

Every flag is cited

Mechanism, evidence source and a PubMed reference behind each warning. No claim without its citation.

Polypharmacy risk

Cumulative anticholinergic, sedative, serotonergic, QT and bleeding load, with Beers 65+ flags.

A safer daily schedule

Timing and food rules worked out for you, so doses that need separating actually get separated.

Reports doctors read

A calm patient summary and an evidence-heavy clinician PDF with mechanisms and PMIDs, in 14 languages.

Emergency card

Allergies, conditions, medicines and a QR for first responders, ready on the lock screen.

Family Cabinet

Up to five profiles, so you can watch over the people you care for from one phone.

Personalised to you

Kidney function (eGFR) and pharmacogenomics aware, so the advice fits your body, not an average one.

The film

Half a minute with the pharmacist who never clocks off.

30 seconds · sound on

No claim without its citation

Every warning explains itself.

Tap any flag and Bolus shows you the mechanism, where the evidence comes from, and how established it is. The engine is the truth; the screen is just the counter.

Mechanism Evidence source Confidence
Serious · talk to your doctor

Sertraline and Amitriptyline

Mechanism

Both raise serotonin (additive effect), and Sertraline inhibits CYP2D6, raising Amitriptyline levels.

The moat

Your medicines are none of our business.

No account. No cloud. No analytics. No ads. Your medicines, doses, allergies, kidney and genetic data are read and checked on your phone, and never sent anywhere.

Don't take our word for it. Switch on Airplane Mode and keep using Bolus. Everything still works, because it was never talking to a server.

Questions

The things people ask first.

Does Bolus replace my pharmacist or doctor?
No, and it never will. Bolus is decision support: it helps you spot what to watch for and gives you a report to discuss. Always check with your pharmacist or doctor before changing anything.
Is my data really private?
Yes. There is no account and no cloud. Your medicines, doses and health details are read and checked on your phone, and never sent anywhere. You can switch on Airplane Mode and keep using Bolus, because it was never talking to a server.
What happens if I go offline?
Everything still works. The safety database and the engine live on your device, so checks, alerts and your daily schedule all run with the network switched off.
Where does the safety information come from?
Curated clinical pharmacology, grounded in public sources: the FDA NDC directory, DailyMed drug labels, PubMed literature, the AGS Beers Criteria® 2023 and CredibleMeds QTdrugs. Every flag carries its mechanism and a citation.
Is Bolus a medical device?
No. Bolus is an informational decision-support tool. It does not diagnose, treat or prevent disease, and it is not a regulated medical device.
How much does it cost?
Every safety check is free, for up to three medications, with no account. Pro is £39.99 a year or £129 once for life, and adds unlimited medications, the Family Cabinet, mechanisms and citations, the optimised schedule and PDF reports.
Everyone, everywhere

Speaks your language.

Bolus reads, checks and explains in fourteen languages, right-to-left included, so a report is ready for any clinician.
