Mounjaro (Tirzepatide) Price in the Philippines 2026

As of 23 September 2026, Watsons Philippines lists 6 Mounjaro KwikPen strengths on its own product pages: 2.5 mg at ₱11,650, 5 mg at ₱13,550, 7.5 mg at ₱20,350, 10 mg at ₱22,950, 12.5 mg at ₱29,900 and 15 mg at ₱29,900. Every Watsons listing is marked prescription required and available through Click and Collect, so the pen is released at a branch against a validated prescription rather than delivered.

Mercury Drug publishes no Mounjaro price online, so this page carries no Mercury Drug figure. Mercury Drug publishes no medicine prices online; its Order Online page is a phone form. A Mercury Drug price has to be asked at a branch or by phone, by strength, as of the day you call. The pharmacies that do publish a Mounjaro price online, checked 23 September 2026, are Rose Pharmacy, Watsons and Southstar Drug.

Mounjaro is the trade name Eli Lilly gives to tirzepatide, a dual GIP and GLP-1 receptor agonist administered as a once-weekly subcutaneous injection. The distinction between the brand and the molecule matters more here than it does in most drug categories, because at least four different things circulate in this country under names that sound interchangeable and are not.

Mounjaro is the registered pharmacy product, dispensed against a prescription, in a KwikPen device. Zepboundis Lilly's other tirzepatide brand, marketed for weight management in the markets that carry it, and covered separately in the Zepbound filing. What Philippine pharmacy shelves actually hold is Mounjaro. Research-grade tirzepatide is a lyophilized powder sold in vials for laboratory research, not a registered medicine, and not the same category of product at all. And compounded tirzepatide is prepared by a pharmacy rather than registered as a product; the compounded tirzepatide guide explains the difference.

People searching "mounjaro philippines price" are almost always asking about the first of those four. That is what the rest of this page answers.

Mounjaro is sold in the Philippines through registered retail pharmacy channels. Watsons Philippines, Southstar Drug and Rose Pharmacy all carry product pages for the KwikPen, and every one of them is flagged prescription required. Watsons routes the product through Click and Collect or in-store pickup rather than ordinary home delivery, and Southstar requires a prescription upload for pharmacist validation before an order is released.

That is the operative fact for a buyer. Mounjaro is not an over-the-counter slimming product and it cannot legitimately be bought as one. A licensed Philippine physician writes the script, a registered pharmacy fills it, and the pen is released against the document. Any seller who skips that step is not offering you a shortcut through paperwork, they are offering you a product outside the chain of custody that makes the paperwork meaningful.

On indication, be precise about what you are asking for. The tirzepatide registration in most markets, including this one, sits with type 2 diabetes first. Weight management indications came later and are handled differently country by country. If your interest is weight rather than glycaemic control, that is a conversation to have openly with a prescriber rather than a detail to leave vague, because it determines whether what you are being prescribed is on-label or off-label for you specifically.

The prices in the table are listings rather than guaranteed counter prices, and they move. When checked, every Watsons strength was restricted to click and collect rather than delivery, and each chain releases the pen only against a prescription validated by its pharmacist. The GLP-1 price tracker covers the whole shelf, and the Ozempic price page covers the semaglutide side. Mounjaro vs Ozempic puts the two side by side, with the SURMOUNT-5 head-to-head result.

Listed and stocked are different words. A product page with a price says the chain sells the strength, not that a given branch holds a pen today.

Hospital pharmacies, such as those at Makati Medical Center, St. Luke's, The Medical City and Asian Hospital, dispense against an in-house or outside prescription and publish no pen prices online.

A practical note on how to ask. Ask a branch for the specific strength on the prescription, by milligram, and how many pens it holds, rather than whether it has Mounjaro.

The supply story for this whole drug class in the Philippines is documented, and the clearest published account is Manila Bulletin's 13 June 2026 report on the semaglutide side. Manila Bulletin described Ozempic prices rising from about ₱6,200 to ₱6,300 per pen to the ₱9,280 now listed at major drugstores, with a Las Piñas pharmacy quoted at ₱11,368. A pharmacist described being directed to start rationing, with patients capped at two pens per dosage per month, and one patient described having stock shipped from Mindanao to Metro Manila to fill a prescription.

Mounjaro sits inside the same squeeze from the other side. Demand for tirzepatide has been climbing precisely because semaglutide supply has been unreliable and expensive, which pushes prescribers and patients toward the alternative and thins that shelf in turn. The Manila Bulletin piece noted Mounjaro as an alternative in the market while also observing it was not available in local pharmacies at the time, and it cited a per-unit figure well below the KwikPen listings above, which is a good illustration of why you should treat any single reported Mounjaro number with care and check a real counter.

The demand side is not mysterious. Manila Bulletin cited roughly 4.7 million Filipino adults living with diabetes and around 27 million classified as overweight or obese. A drug class with that addressable population and a global manufacturing bottleneck that started in 2022 was never going to sit quietly on a shelf in Manila. Expect intermittent stockouts to be the normal condition of this market rather than a passing phase.

The device matters for price comparison, so it is worth being exact. Eli Lilly medical information states that each Mounjaro KwikPen contains four doses. It is a multi-dose device with a dial, not a single-shot autoinjector.

Six strengths are sold in the Philippines: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg. The 2.5mg pen costs nearly as much as the 5mg pen for half the drug. A Mounjaro price that does not name the strength is not a price.

The gap between a ₱30,000 pharmacy pen and a marketplace listing at a fraction of that is exactly the gap counterfeiters work in. Facebook groups, Shopee and Lazada reseller pages and Viber sellers are the documented informal channel for GLP-1 pens in this region, and a labelled box tells you nothing about the contents, the batch or the temperature history. The counterfeit GLP-1 filing goes through what has actually been found in this market.

Enforcement is not theoretical either. The NBI arrested two people in Tondo, Manila on 13 May 2026 for selling unregistered tirzepatide online, seizing about ₱310,000 in product, with the case built on RA 9711 section 10(j) alongside RA 10175 and RA 7394. Two weeks later, on 27 May 2026, the NBI and FDA raided an aesthetic clinic in Pasig over unregistered whitening and slimming injectables. Those are the two ends of the same problem: the online seller and the clinic that buys from one.
