Two ways in
Pharmaceutical care
The clinical half of the site: one search across every tool, the clinical queries you get at the counter, and the tools behind them.
- Interactions, paediatric dosing, pregnancy and breastfeeding
- Point-of-care screening and clinical calculators
- Every answer traced back to a named source
Academy
Training for pharmacists and technicians: the AI School for using artificial intelligence safely in a pharmacy, and short training pills on medicines.
- Lessons, worked cases and marked exercises
- One free account for every school
- The same courses in English and in Spanish

The six most-used tools. Everything else — 17 more, from a full drug reference to a travel health kit — is on the complete list.
Drug interactions
Check a whole medication list, pair by pair, with what to do about it at the counter.
OpenPaediatric dosing
mg/kg to mL of the actual bottle, by weight or age.
OpenPoint-of-care screening
Blood pressure, glucose, lipids, SCORE2, PHQ-2, AUDIT-C — in mg/dL or mmol/L.
OpenPregnancy & breastfeeding
Is this medicine safe in pregnancy or breastfeeding?
OpenPharmaceutical care
56 clinical queries and one search across every tool on the site.
OpenDrug reference
Brand name to active ingredient, and the fact sheet behind it.
OpenCommon questions at the counter
The interaction pairs pharmacists get asked about most — each with the verdict, the mechanism and what to say.
NSAIDs & warfarin
Ibuprofen against warfarin or acenocoumarol — the most common serious interaction at the counter.
OpenNSAIDs & antidepressants
Ibuprofen against an SSRI or SNRI — a very common pairing with a real bleeding risk.
OpenNSAIDs & lithium
A short course of ibuprofen can push lithium into the toxic range within days.
OpenNSAIDs & blood pressure medicines
ACE inhibitors or ARBs, plus a diuretic, plus an NSAID — the "triple whammy".
OpenNSAIDs & DOACs
Apixaban, rivaroxaban, dabigatran or edoxaban — newer does not mean the bleeding risk is gone.
OpenParacetamol & warfarin
The reassuring one — still first-choice, with one caveat on prolonged high-dose use.
OpenBuilt from official sources, not a search engine
Every answer traces back to a named source — the Spanish medicines database CIMA-AEMPS, the Spanish Paediatric Association, or a validated clinical score — and says so. Where AI fills a gap, it is marked as AI, with a reminder to check the official product information. See the clinical content policy for exactly where each tool draws the line, and how AI is used.
Frequently asked questions
Who built this, and why is the site called “Convenio de Farmacia”?
Antonio, a Spanish community pharmacist who also writes software. The site started as a payroll calculator for the Spanish pharmacy collective agreement — that is what the Spanish name means — and grew a set of clinical tools and an academy alongside it. This English section covers both: the clinical tools and the training.
Is it free, and do I need an account?
Every tool here is free with no account. A free account adds a couple of extras — saving a review, personal alerts — but nothing you need to get an answer at the counter.
Whose clinical guidance is this — Spanish or my own country’s?
The clinical content — mechanisms, doses, safety in pregnancy — is not specific to Spain. What is Spanish is the regulatory layer: which medicines need a prescription, and which official body to check. Each tool says so where it matters, and links to your own country’s source rather than assuming Spain’s.
What is in the academy?
Two things: the AI School, four levels on using artificial intelligence in a pharmacy without putting anyone at risk (Level 1 needs no account, Levels 2 and 3 need a free one, Level 4 is paid), and Pharmacy Pills, short study notes on medicines, supplements, herbal products and skincare with a free quiz on each. Pills read in full without an account where it matters most (the warnings); a free account opens the rest.
Can I install this as an app?
Yes. On Android or desktop Chrome/Edge you will be offered an install prompt; on an iPhone, open the Share menu and choose “Add to Home Screen”. It works offline once loaded, with no app-store account.
