This is the intense moment a customer argued with a pharmacist over medication.

Joan DV Alcudia confronted a male pharmacist for refusing to sell her Irbesartan medicine, to treat hypertension, without a prescription in Cebu, the Philippines, on April 24.

Footage shows the exchange between the customer and the healthcare worker.

Despite the pharmacist explaining multiple times why they couldn't dispense the pills, the customer and her friend persisted in questioning him.

He even sought assistance from a colleague as the customer remained adamant about purchasing the product, arguing that they could obtain it from another pharmacy without a prescription.

In an attempt to shame the healthcare workers, the woman posted about the incident online to garner sympathy from her followers.

However, medical professionals supported the pharmacists, and she faced criticism instead.

Pharmacists adhere to protocols requiring prescriptions for medication dispensation.
