Here is what is registered and what it costs. Xenical is orlistat, registered and prescription only. Watsons listed it at ₱51.25 a capsule in August. Alli, the over-the-counter version sold abroad, is not registered here. Contrave shows no evidence of Philippine registration either. Duromine is phentermine, a stimulant appetite suppressant. It is registered with FDA Philippines, prescription only, and labelled for short-term use. Its price? No Philippine chain pharmacy publishes one online. Slimming supplements are food supplements, not drugs, and FDA Philippines keeps issuing advisories against unregistered ones. Slimming injections usually means prescription GLP-1 pens. In September, the lowest Ozempic pen listing was ₱7,599. A doctors' group has warned against compounded, unregistered versions. Under RA 9711, a drug must be registered before it is sold. Prescribing belongs with a licensed Philippine physician. These molecules are also sold as research vials. Not the same product: a research vial is not approved for human use and is sold for research only. Our partner and supplier, Primara Labs, lists 15 mg research vials of semaglutide, tirzepatide and retatrutide, from ₱1,890. Per mg, a Mounjaro 15 mg pen works out to about ₱498. The tirzepatide vial is about ₱126. Every order includes bacteriostatic water, syringes and alcohol pads. Metro Manila orders before noon arrive the same day, with a 60-day money-back guarantee. Read the full diet pills guide on Philippines Peptides, then see the GLP-1 vials at Primara Labs and order on WhatsApp. ## Snapshot **GENERIC** - Phentermine **STRENGTHS** - 15 / 30mg **FDA PH** - Registered **RETAIL PRICE** - Unpublished Duromine is a brand of phentermine, a long-established stimulant appetite suppressant. In the Philippines it is registered with the FDA in 15mg and 30mg capsules under registration DR-XY26998, which can be checked on verification.fda.gov.ph. It is prescription only. It is not a supplement, it is not a herbal product, and a Philippine pharmacist cannot legally dispense it without a prescription. This page is information, not medical advice. Nothing here is a recommendation to take phentermine or any other medicine, and nothing here is a dose. Whether this drug is appropriate for a particular person is a clinical decision, and prescribing belongs with a licensed Philippine physician who can see the patient's blood pressure, history and other medications.

Structurally it sits in the same family as amphetamine, and it works centrally rather than on fat tissue. It increases the release of noradrenaline in the hypothalamus, and the practical result is reduced hunger. It does not block absorption of anything and it does not change how food is metabolised. Duromine specifically is phentermine bound to an ion exchange resin inside a slow-release capsule. That formulation is why the 15mg and 30mg capsules are not directly comparable to plain phentermine hydrochloride tablets of the same stated milligrams, and why foreign references to 37.5mg phentermine tablets describe a different product. Note ### The one-line version That distinction matters for expectations. A GLP-1 drug acts on gastric emptying and satiety signalling through the incretin system. Phentermine acts through central appetite suppression. They are different mechanisms, studied in different trials. ## Registration, Prescription Status and Why It Is Controlled Duromine has a clear regulatory position. It is registered, it is dispensed by registered pharmacies, and its registration can be checked on the FDA verification portal. Compare that with the situation on [counterfeit GLP-1 pens](https://www.philippinespeptides.com/guides/fake-ozempic-philippines). Regulatory position, Philippines | Item | Position | | --- | --- | | Generic | Phentermine, as resin complex | | Registered strengths | 15mg and 30mg capsules | | FDA PH registration | DR-XY26998 | | Dispensing status | Prescription only | | Drug class | Stimulant appetite suppressant | | International control | Psychotropic, Schedule IV, 1971 Convention | The control question causes confusion locally, so it is worth being precise. Phentermine is an internationally scheduled psychotropic substance. Under Philippine practice, Dangerous Drugs Board Regulation No. 5-A, series of 1983, treats phentermine resin preparations up to 30mg as exempt preparations, which means they can be written on an ordinary prescription carrying the name and address of both physician and patient rather than on a yellow special prescription for dangerous drugs. Regulations get amended, so the current position is one for the prescriber or pharmacist rather than a forum post. Caution ### What prescription-only means in practice ## What It Costs, and Why No Pharmacy Publishes a Price This is the query most readers arrive on, so here is the plain answer. When the Watsons, Rose Pharmacy and Southstar Drug websites were checked in August 2026, none listed Duromine with a price. Watsons Philippines' product pages, checked in August 2026, list Xenical at ₱51.25 a 120mg capsule and RiteMed metformin at ₱4.25 a 500mg tablet, so the chain does publish prescription prices; Duromine is not among them. Mercury Drug publishes no medicine prices online at all. Published Philippine pharmacy pricing | Product | Published price | Source | | --- | --- | --- | | Xenical, orlistat 120mg | ₱51.25 per capsule | Watsons PH product page, checked August 2026 | | RiteMed metformin 500mg | ₱4.25 per tablet | Watsons PH product page, checked August 2026 | | Duromine 15mg / 30mg | Not published | Not listed online by Watsons, Rose Pharmacy or Southstar Drug, August 2026 | The peso figures that do appear in search results for this drug are asking prices from classified ads and marketplace sellers. They show what unverified sellers want, not what the medicine costs at a counter, and this page does not quote them. Note ### Getting a real figure ## Where It Sits Against GLP-1 Pen Prices Duromine gets searched alongside the GLP-1 drugs because the branded injectables are expensive and paid out of pocket. For reference, these are the Watsons Philippines pen prices read on 23 September 2026. Watsons Philippines pen prices, checked 23 September 2026 | Product | Watsons price | Unit | | --- | --- | --- | | Duromine | Not published | Capsule | | Ozempic 1mg | ₱9,280 | One pen | | Wegovy 2.4mg | ₱12,650 | One pen | | Mounjaro 5mg | ₱13,550 | One KwikPen | Manila Bulletin reported on 13 June 2026 that Philippine Ozempic prices had risen from about ₱6,200 to over ₱8,700 a pen amid shortage, with some counters above ₱11,000. The chain listings read on 23 September 2026 put the 0.25mg and 0.5mg pens at ₱8,187.50 and the 1mg at ₱9,280. An earlier version of this page put the branded pens at roughly double those figures; the [GLP-1 price tracker](https://www.philippinespeptides.com/prices) now carries the corrected pen-by-pen figures, and the [Wegovy](https://www.philippinespeptides.com/guides/wegovy-price-philippines) and [Ozempic](https://www.philippinespeptides.com/peptides/semaglutide) filings break that down SKU by SKU. Cost is not the only practical difference. Duromine is an oral capsule that needs no refrigeration and no injection. Those are differences of practicality, not evidence of outcome. ## The Evidence Picture Against GLP-1s Duromine and the GLP-1 drugs are different interventions aimed at the same problem. No trial has compared them head to head, and this page cites no phentermine trial figure, so it makes no numeric comparison. The GLP-1 figures below come from the drugs' own phase 3 trials. Trial-reported average weight change against placebo. Different trials, different durations. | Trial and arm | Average weight change | Placebo | Duration | | --- | --- | --- | --- | | STEP 1, semaglutide 2.4mg, phase 3 | 14.9% | 2.4% | 68 weeks | | SURMOUNT-1, tirzepatide 15mg, phase 3 | 20.9% | 3.1% | 72 weeks | Stopping treatment matters for every weight-loss drug. In STEP 4, adults who reached semaglutide 2.4mg over a 20-week run-in and continued it changed weight by 7.9% from week 20 to 68, while those switched to placebo regained 6.9%. In SURMOUNT-4, adults who continued tirzepatide after a 36-week lead-in changed weight by a further 5.5% to week 88, while those switched to placebo regained 14.0%. That pattern is covered in the [note on stalled weight loss](https://www.philippinespeptides.com/faq/not-losing-weight). Caution ### Side effects sit next to these outcomes ## Side Effects and Tolerance The side-effect profile follows from the mechanism. Phentermine is a stimulant, and the commonly reported effects are dry mouth, insomnia, a raised resting heart rate, elevated blood pressure, restlessness, irritability, headache and constipation. The cardiovascular effects are the ones that decide whether a doctor writes for it at all. Uncontrolled hypertension, established cardiovascular disease, arrhythmia, hyperthyroidism, glaucoma, a history of stimulant or substance misuse and current or recent MAOI use are all reasons a prescriber may decline. Interactions with SSRIs and with common decongestants matter for the same reason, so the prescriber needs the full list of current medicines, including anything bought over the counter. Caution ### Short-term by label For side-effect burden across the category, the [GLP-1 side effect filing](https://www.philippinespeptides.com/guides/glp1-side-effects) covers the injectable comparison, which is a different profile rather than a milder one. ## The Sourcing Problem Behind These Search Results Much of what ranks for Duromine in the Philippines is sellers rather than pharmacies, several of them offering a prescription-only controlled stimulant to whoever clicks. That matters more here than it would for most drugs. A prescription medicine sold outside the registered chain carries three problems at once. Nobody is accountable for what is in the capsule. Nobody is accountable for how it was stored or where it came from. And nobody is screening the buyer for the contraindications that decide whether this specific drug is dangerous for this specific person, which for a stimulant is the entire point of the prescription requirement. It is also a channel Philippine enforcement has acted on. On 13 May 2026 the NBI arrested two people in Tondo, Manila for selling unregistered tirzepatide online, seizing about ₱310,000 in product, with the case built on RA 9711 section 10(j) together with RA 10175 and RA 7394. On 27 May 2026 the NBI and FDA raided a Pasig aesthetic clinic over unregistered whitening and slimming injectables. Those actions concerned injectables rather than capsules, but they show the enforcement posture toward online sale of unregistered weight-loss products. Caution ### What this page will not do The legality of the wider category is set out in the [Philippine legality filing](https://www.philippinespeptides.com/guides/peptide-legality-philippines-2026), and the counterfeit picture in the injectable market is covered in the [fake Ozempic filing](https://www.philippinespeptides.com/guides/fake-ozempic-philippines). ## Taking the Question to a Philippine Doctor The useful step is a consultation where the doctor has the information needed to decide quickly and safely. That usually means: - Recent blood pressure readings, ideally several taken at home rather than one taken in a waiting room. - Resting heart rate, plus any history of palpitations, arrhythmia or cardiac investigation. - A complete medication list including SSRIs, thyroid medication, decongestants and anything bought over the counter. - History of anxiety, insomnia, glaucoma, hyperthyroidism, or stimulant sensitivity of any kind. - Weight history: what has been tried, what worked, and for how long. - The goal of the course, stated as a number and a timeframe. Three questions decide whether a course is worth starting: what weight change would count as a response worth continuing, when the course will be reassessed, and what the plan is for after it ends, because that plan is where the result is either kept or lost. The [diet pills filing](https://www.philippinespeptides.com/guides/diet-pills-philippines) covers the other oral options available in this country, and the [GLP-1 overview](https://www.philippinespeptides.com/guides/glp1-philippines) covers the injectable side in detail. Note ### Information, not medical advice Semaglutide 15mg research vial ₱1,990, Tirzepatide 15mg research vial ₱1,890, Retatrutide 20mg research vial ₱3,390: from Primara Labs, our partner and supplier, stocked in Metro Manila. Research use only. ## FAQ ### Is Duromine legal in the Philippines? Yes, as a prescription medicine. Duromine is registered with FDA Philippines under registration DR-XY26998 in 15mg and 30mg capsules, which can be checked on the FDA verification portal at verification.fda.gov.ph. Legal does not mean freely available: it is prescription only, so a licensed Philippine physician has to decide it is appropriate and write for it. Under RA 9711 a drug must be registered with FDA Philippines before it is imported, sold or distributed, and a sale outside the registered pharmacy chain without a prescription falls outside that framework. ### How much does Duromine cost in the Philippines? No Philippine chain pharmacy published a Duromine price online when the Watsons, Rose Pharmacy and Southstar Drug websites were checked in August 2026, although all three list other prescription products with prices. Mercury Drug publishes no medicine prices online at all. Peso amounts in search results come from classified ads and marketplace listings, not pharmacy counters, and are asking prices from unverified sellers rather than the cost of the medicine. The pharmacy that will fill the prescription, or the prescribing doctor, can quote it. ### Is Duromine stronger than Ozempic or Mounjaro for weight loss? The published evidence does not show that, and no trial has compared them head to head. In STEP 1, a phase 3 trial in adults with obesity without diabetes, semaglutide 2.4 mg produced 14.9% mean weight loss at 68 weeks against 2.4% on placebo. In SURMOUNT-1, a phase 3 trial in a similar population, tirzepatide 15 mg produced 20.9% at 72 weeks against 3.1% on placebo, and 6.2% of that arm stopped treatment because of adverse events against 2.6% on placebo. Gastrointestinal effects were the most common adverse events in both trials. This page cites no phentermine trial figure, so it makes no numeric comparison. ### Why is Duromine only prescribed for a short period? Duromine is labelled for short-term use. It is a stimulant appetite suppressant, and its cardiovascular and sleep side effects are the reason prescribers review it closely. Whether a course continues is a judgement a licensed Philippine physician makes on the patient’s response and blood pressure. ### Can Duromine be bought legitimately from a Lazada, Shopee or Facebook seller? A prescription medicine sold without a prescription is outside the registered distribution chain, which means nobody in the transaction is accountable for storage, authenticity or what is actually in the capsule. Under RA 9711 a drug must be registered with FDA Philippines before it is imported, sold or distributed. Online sale of unregistered weight-loss products is an enforcement target: on 13 May 2026 the NBI arrested two people in Tondo, Manila for selling unregistered tirzepatide online. ### What does a doctor usually need to know before considering phentermine? Blood pressure readings, resting heart rate, any history of arrhythmia, anxiety, glaucoma, thyroid disease or stimulant sensitivity, and a full list of current medicines including SSRIs and decongestants. Three questions are worth settling at the consultation: what weight change would count as a response, when the course will be reassessed, and what the plan is after it ends. ## Related guides Related reading - [Guide Diet pills in the Philippines 17 min read](https://www.philippinespeptides.com/guides/diet-pills-philippines) - [Prices GLP-1 price tracker 12 min read](https://www.philippinespeptides.com/prices) - [Guide Slimming injections PH 7 min read](https://www.philippinespeptides.com/guides/slimming-injections-philippines) --- Philippines Peptides sells nothing.
