GLP-1 & Weight Loss Injections

GLP-1 Refill Subscriptions for Shopify Brands in India

For licensed pharmacies and weight-management programmes selling semaglutide or tirzepatide: run monthly pen refills, dose-step plans and companion nutrition on subscription. Offer prepaid, pay-as-you-go and AutoPay on UPI and cards side by side, with StackBack, the subscription & repeat-revenue platform for Indian D2C brands on Shopify. Our team takes you live in 2 days.

Weekly Doses, Monthly Refills Adherence Depends on the Next Pen Arriving

GLP-1 treatment runs on a fixed rhythm: one injection a week, one pen or four weeks of vials a month, and dose steps every few weeks as the doctor directs. A late refill means a missed dose. StackBack keeps the refill on schedule, so the protocol doesn't break.

AutoPay on UPI and cards for the monthly refill: The patient approves once. Each refill is paid on schedule into your own gateway, with a notice 48–72 hours before. Payments up to ₹15,000 go through without an OTP.
Prepaid for a 3-month programme: A full course of refills, coaching and nutrition paid once. It suits higher-value plans.
Pay-as-you-go while the dose is set: A payment link before each refill, for patients in their first months.
Dose steps as plan changes: Each strength is a variant. Once the doctor confirms, your team schedules the next strength from a set delivery, or the patient switches in the portal.
Companion nutrition in the same box: Protein, fibre and electrolytes that ship with the refill.
Needles and swabs on every delivery: Bundled with the pen, so the kit is always complete.

Proof: Over 100 brands run repeat revenue on StackBack, with ₹90 Cr+ GMV powered.

Why GLP-1 Patients Drop Off And How to Keep the Protocol on Track

Patients rarely stop GLP-1 treatment in one decision. A refill arrives late, a dose is missed, restarting after a gap brings side effects back, and the programme quietly ends. Since semaglutide generics reached India in March 2026, a patient who lapses can also restart with a cheaper brand.

Most programmes manage refills by phone, WhatsApp and spreadsheets. That works for 100 patients. With dose steps changing every few weeks, it breaks well before 1,000.

Put the refill on a schedule, with monthly pens or vials paid and dispatched before the last dose is used.
Keep dose changes clean, with every strength as a variant, changed in the portal or by your team when the doctor confirms.
Sell the programme, not just the pen, with refills, companion nutrition and needles on one plan.

Result: Better adherence, steadier monthly revenue and fewer refill calls for your care team.

Frequently Asked Questions

How do I launch GLP-1 refill subscriptions on Shopify in India?

Integrate StackBack with your Shopify store, and our team sets up your refill, dose-step and programme plans on prepaid, pay-as-you-go and AutoPay on UPI and cards. We take you live in 2 days. Your prescription and dispensing process stays as it is.

Can a subscription follow dose escalation?

Yes. Each strength is a variant. When the doctor moves a patient up a dose, your team schedules the new strength from a set delivery, or the patient switches in the portal. The next refill ships at the new strength.

Does StackBack check prescriptions?

No. Prescriptions are your brand's responsibility, and StackBack has no part in them. A subscription only schedules the refills and charges each one through your own payment gateway. Each refill reaches your team as a Shopify order before it's dispatched.

Which GLP-1 medicines can be sold this way?

Any your pharmacy is licensed to sell, including semaglutide (Ozempic, Wegovy and the generics launched in India since March 2026) and tirzepatide (Mounjaro). Each pen, vial and strength runs as its own variant.

Can patients pay for refills with AutoPay?

Yes. On StackBack's subscription checkout, the patient pays for the first refill and sets up AutoPay on UPI or a card in the same step. Payments up to ₹15,000 go through without an OTP, each with a notice 48–72 hours before. For higher-value programmes, a prepaid plan is often simpler. If a payment fails, it's retried, and after three failed retries the plan pauses or moves to pay-as-you-go, whichever you choose. Nothing ships unpaid. How AutoPay works.

Can patients pause treatment?

Yes. They pause, skip or reschedule from the portal when their doctor pauses treatment or they travel, and resume without a new sign-up.

Can I sell companion nutrition alongside refills?

Yes. Protein, fibre, electrolytes and supplies can ship in the same box as the refill, run as their own plan, or be added to an upcoming delivery from the portal.
