When official medicine prices change in Spain: a 2026-2027 calendar.

For a pharmacy that means twelve fixed dates a year, four busier ones and an autumn window when old and new prices coexist. This guide puts them in one calendar, with the rule behind each date. It is written for pharmacy owners, managers of pharmacy groups and suppliers working with Spanish pharmacies who need the dates rather than the policy debate.

The monthly cycle: from the 20th to the 1st

The Nomenclátor oficial de la prestación farmacéutica is the official list of medicines and products the National Health System (SNS) funds through community pharmacies, with their prices. Royal Decree 177/2014 sets its rhythm:

The nomenclator is made available electronically to public administrations and to the General Council of Official Colleges of Pharmacists (art. 13.1). Pharmacies do not download it themselves: their management system receives it through a medicines database, usually the Council's own BOT PLUS. The Ministry also publishes it online in CSV, RDF and Excel; the current edition as we write is November 2026.

In practice, a change approved on the 22nd does not reach next month's list but the one after, and a change announced mid-month is not charged at the till until the 1st.

The four lowest-price months

Homogeneous groups bring together interchangeable presentations with the same active ingredient, dose, pharmaceutical form and pack size. A group's lowest price is that of its cheapest presentation, and it drives substitution at the counter.

Article 8.6 of Royal Decree 177/2014 sets a quarterly review, fixed automatically in the January, April, July and October nomenclators. The Ministry publishes the list of homogeneous groups and lowest prices on the same cycle; the latest available update is October 2026. Pharmacies dispensing many generics feel those four 1sts more than the rest.

The annual reference-price order

The reference-price system sets the maximum amount the SNS pays for each set of medicines. It is updated once a year by ministerial order (art. 5), with the procedure starting in April. Article 6 sets the deadlines:

• Manufacturers supply at the new price from the date the order applies.
• Wholesalers may sell existing stock at the old price for twenty calendar days.
• Pharmacies may sell affected stock at the old retail price until the last day of the first following month.
• New reference prices enter the nomenclator that applies on the first day of the second following month, and SNS prescription billing is settled at the new prices from then.

The last three orders:

The Ministry confirmed the 2024 and 2025 old-price deadlines in its press releases. The 2026 dates follow from applying article 6 to the effective date set in the order itself (the day after publication). According to the Ministry, the 2024 order revised 17,655 presentations and the 2025 order 17,385.

The mechanism is the same when the order lands in another month. Order SND/1308/2021 applied from 30 November 2021, and the General Council of Pharmacists explained in its journal that its reductions would appear in the nomenclator for January 2022 billing: the second following month, as article 6 requires. With an October order, December is the month to watch.

Month by month to December 2027

Closing and application dates are fixed by law; the 2027 order date is a forecast based on the last three.

Price changes outside the calendar

• Decisions of the Interministerial Committee on Medicine Prices (CIPM). It sets the maximum ex-factory price of medicines. Its 2026 calendar proposes eleven sessions, with two left: 18 November and 16 December. Treat these as indicative: session 273 met on 2 September, not on the 23rd as scheduled. Its agreements only take effect once the Ministry's directorate for the SNS common service portfolio and pharmacy issues the final resolution and the change reaches the billing nomenclator.
• Non-reimbursed medicines. Prices are notified by the laboratory and can change on any day; see what an EFP is and how the retail price is set.
• Parapharmacy and promotions. Set by the pharmacy, within the rules in the pricing and advertising rules guide.

A routine for the pharmacy team

1. From the 25th to month-end: check the management system has received the database update; most show the date of the last load.
2. On the 1st: check three or four reference products you know are changing, comparing till and shelf.
3. In January, April, July and October: extend the check to your fastest-moving generics.
4. From the reference-price order to 30 November: identify old-price packs still in the stockroom. They sell at that price until month-end and at the new one from 1 December.
5. In December: repeat the check on the sets affected by the order.

Each step of the chain, from official source to software to shelf, is covered in changing pharmacy prices automatically.

What labels and screens should do on those dates

With paper labels, every date in this calendar is a task. With electronic shelf labels, the task disappears only if the label reads its price from the same system as the till; otherwise the 1st of each month becomes a risk day again, as described in why shelf and till prices drift apart.

The October-November window is the trickiest: some packs sell at the old price while new stock arrives at the new one. The label should not calculate anything itself; it should show what the management system charges at that moment. How each Spanish system (Farmatic, Unycop, Nixfarma) connects is covered under pharmacy software integrations.

This guide summarises national rules. It does not replace your professional college's guidance or a reading of the official text, linked in each case.
