## Lowest price by strength and form

| Product | Lowest price | Where | Pharmacies |
| --- | --- | --- | --- |
| [400 mg tablet](#400-mg-tablet) | ₱2.10 / tablet | Isonix at Philippine Generic Medicines | 2 |

Each table is in the page's order: pharmacies by their lowest price in stock, and each pharmacy's other listings after its lowest. A price reported to DOH has no product page: Mercury Drug's name links to its online order form, and Generika's online store is closed for maintenance, so it has no link.
