Finding an on-call pharmacy in Dakar at 2 a.m. is still a struggle in 2026. The National Pharmacists Order publishes the weekly list every Friday evening, but it circulates as a PDF across 47 WhatsApp groups and gets lost. A pharmacy that automates its on-call alerts via SMS and WhatsApp Business turns a public service into a durable acquisition lever.
TL;DR
- Official on-call list released every Friday by the Pharmacists Order
- Customer SMS subscription: XOF 800 to 1,500 per month, median XOF 1,000
- Outbound SMS wholesale cost in Senegal: XOF 8 to 12 via Orange API, XOF 15 via aggregator
- WhatsApp Business API: XOF 5 to 7 per utility message outside the 24h window
- A typical pharmacy reaches 300 to 800 subscribers in 6 months with a clean storefront
Why on-call SMS is still a local asset
Dakar has more than 600 pharmacies spread across Plateau, Médina, HLM, Mermoz, Sacré-Coeur, Almadies, Parcelles Assainies, Pikine, Guédiawaye and Rufisque. Each district has 4 to 8 on-call pharmacies per shift, rotating weekly. End customers never memorize the rotation — they call around, pay a Yango ride for nothing and walk away frustrated.
A pharmacy that positions itself as "the one that warns you before the shift" earns rare attention. SMS costs XOF 8 to 12 wholesale via Orange Senegal or Free Senegal SMS API. At XOF 1,000 monthly subscription for 4 to 8 SMS, gross margin tops 90%.
Three use cases that genuinely work
- Neighborhood subscription: a patient signs up with a number, receives every Friday night the on-call pharmacy for THEIR area only.
- Renewable prescription alert: a chronic patient gets a J-3 reminder before treatment ends, with a reservation link.
- Delivery pre-order: a WhatsApp message with a click-to-WhatsApp link to reserve meds before driving over.
Architecture compliant with the Order
The National Pharmacists Order of Senegal regulates pharmaceutical advertising. A factual, non-promotional on-call notification is still allowed. Unwritten rule: never name a drug in the SMS, never offer a discount on prescription.
| Component | 2026 recommended choice | Monthly cost |
|---|---|---|
| Database | Postgres Neon serverless | XOF 0 free tier up to 500 subs |
| Backend API | Next.js 14 + Prisma | VPS hosting XOF 6,000 |
| SMS gateway | Orange SMS API or InTouch | XOF 8 to 15 per SMS |
| WhatsApp Business | Meta Cloud API direct | XOF 5 to 7 utility message |
| Subscription billing | Wave Business 1% | included |
| Domain plus pro email | OVH or Hostinger | XOF 1,200 smoothed |
SMS remains the most universal channel — many older patients have no WhatsApp. But WhatsApp adds click-to-call and prescription photo upload.
Simple signup flow
- Step 1: customer scans an in-store QR code or clicks a WhatsApp link.
- Step 2: 3-field web form — number, neighborhood, first name.
- Step 3: Wave redirect to pay XOF 1,000 monthly subscription, manually recurring.
- Step 4: instant SMS confirmation and database insertion.
- Step 5: every Friday 7 p.m. a cron sends the list filtered by neighborhood.
Pricing and realistic economics
A pharmacy with 500 subscribers at XOF 1,000 grosses XOF 500,000 monthly. Variable costs (SMS, hosting, Wave) hover around XOF 60,000. Net margin around 88%. At 1,000 subscribers the margin climbs to 92% thanks to hosting economies.
| Subscribers | Monthly revenue XOF | Variable costs XOF | Net margin XOF |
|---|---|---|---|
| 100 | 100,000 | 18,000 | 82,000 |
| 300 | 300,000 | 42,000 | 258,000 |
| 500 | 500,000 | 60,000 | 440,000 |
| 1,000 | 1,000,000 | 95,000 | 905,000 |

Acquisition is the real cost: count XOF 800 to 1,500 per subscriber via Facebook Ads or in-store flyer. At XOF 1,500 acquired for 12 months of subscription, ROI stays solidly positive.
Three pitfalls to avoid
Several Dakar pharmacies tried and quit within 6 months. Causes are almost always the same:
- Mass send without segmentation: blasting all 8 districts to every subscriber kills perceived value.
- Non-automated billing: chasing 500 clients manually each month eats a full-time job.
- No clear opt-out: without a working STOP, the service becomes spam and falls under data protection law 2008-12.
FAQ
Q: Do I need Order authorization to send on-call SMS?
A: No for an informational service billed to the patient. Yes the moment a product promotion or brand partnership appears. Read the 2024 National Council ruling before launch.
Q: Which SMS gateway should I pick in Senegal in 2026?
A: Orange SMS API offers the best national coverage. InTouch is easier for a solo developer. International Twilio costs 4 to 5 times more and is unreliable on Free.
Q: Is WhatsApp Business enough without SMS?
A: No. Nearly 30% of pharmacy clients are over 60 and use a basic phone. SMS stays essential not to lose that segment.
Q: How much does Kolonell charge to deploy the system?
A: The on-call pharmacy pack runs around XOF 850,000 setup plus XOF 35,000 monthly for maintenance and gateways. Quote at kolonell.com/en/devis-gratuit.
