What changes for a pharmacy with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday pharmacy situations before and after the CertuAI agent.
TodayA customer calls asking if you have a certain medication and nobody picks up at peak hours
With CertuAIThe agent confirms availability and price right away, on WhatsApp
TodayA delivery order jotted down in a hurry, with a risk of getting the item or address wrong
With CertuAIOrder logged in writing in the conversation, checked before it goes out for delivery
TodayA line at the counter just to find out if an item is in stock
With CertuAIWhoever asks on WhatsApp already knows before leaving home
TodayNobody knows whether the pharmacy is on duty at that hour
With CertuAIThe agent gives the hours and whether there is an on-duty shift, right away
What does a conversation handled by the AI look like?
Example conversation
Pharmacy AI agent
Customer: Do you have this medication in stock?
AI agent: Tell me the name and the presentation and I'll check the pharmacy's list.
Customer: Do you deliver? How long does it take?
AI agent: We do. Send me the address and the payment method and I'll log the order.
Is an AI agent or manual service better for pharmacies?
The agent wins at tasks that repeat, and the person keeps winning at what takes judgment. With manual service someone at the pharmacy has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Question about a specific medication | Customer calls, nobody answers at the counter's peak hours | The agent confirms availability and price right away |
| Delivery order | Jotted down by phone, with a risk of error on the address or item | Logged in writing in the conversation, with the address and item checked |
| Night-shift on-duty pharmacy | Customer finds out by calling or going there | The agent says whether it is open and until what time |
| Line at the counter for a simple question | Everyone waits for the same answer on price or availability | Solved on WhatsApp before the person leaves home |
What does the WhatsApp agent do for pharmacies?
It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers clients your way, with your rules.
Availability and price lookup
The agent checks whether the item is on the list you keep updated and gives the price, which saves the person a trip to the counter just to find out it's out of stock.
Written delivery orders
Item, presentation, address and payment method are logged in the conversation, without the risk of getting a dosage or street wrong on an order jotted down by phone.
Generic and similar of the same substance
The agent states which options with the same substance are in stock and the price of each, leaving the choice to the customer and the guidance to the pharmacist.
Opening hours and on-duty shifts
Answered at any hour, including the middle of the night, which is exactly when the on-duty question comes up.
Handoff to the pharmacist
A question about use, dose, interaction or indication leaves the automatic conversation and goes to your team, never answered by the agent.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday pharmacy messages no longer depend on you having your phone in hand.
How does the agent start answering for a pharmacy?
In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp for pharmacies cost?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.

Create my agentWhat needs to be ready before turning on the agent for a pharmacy?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The line between what the agent answers and what goes to the pharmacist: price, stock, delivery and hours on one side, use and indication on the other
- How the item list is checked and how often it is updated
- The rule for controlled medication: what requires a prescription and what requires presence at the counter
- Delivery neighborhoods, fee and average time by area
- Opening hours and the on-duty dates of the month
- Insurance plans and discount programs the pharmacy accepts
Whether the agent confirms the price of high-turnover items in the conversation or whether every price is checked by someone at the counter before it goes out.
The most common mistake: Not writing down the pharmacist's boundary. The effect, dose and substitution of one medication for another are the responsibility of the technical manager, and that rule needs to live inside the Brain, not be assumed in the team's heads. Read how to fix this.
Pharmacy FAQ
Does the agent recommend medication or give directions for use?
No. It answers availability, price, delivery and hours. Any guidance on use stays only with the responsible pharmacist.
Does this replace the pharmacist?
No. The agent handles the administrative side. Technical questions are passed to your team, as they should be.
Does it work for controlled medication?
The agent can let the customer know when the order is ready for pickup, but the sale of controlled medication follows the normal rules, with a prescription and presence at the counter when required.
Can it be used across more than one location?
Yes, you configure the agent per location and it routes orders and deliveries according to the customer's address and that store's stock list.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?

In short
Availability, price and delivery answered before the customer leaves home. Questions about use go to the pharmacist and the order is written down in the CRM.
