Injecting yourself with Ozempic, Mounjaro, Saxenda, or Victoza for the first time is daunting. Most Indian users receive a brief demonstration at the pharmacy or clinic — sometimes none at all — and are sent home to figure it out.
Getting the injection technique right matters. Incorrect technique leads to injection site reactions, pain, bruising, inconsistent drug absorption, and in the worst cases, wasted doses of medication that cost thousands of rupees.
This guide walks you through everything: the correct injection sites, the right technique, common mistakes, storage, and what to do if something goes wrong.

Most GLP-1 medications come in pre-filled injection pens — not syringes. Understanding your pen before injecting is essential.
Common GLP-1 pens available in India:
| Medication | Brand | Pen Type |
|---|---|---|
| Semaglutide 0.5 mg/1 mg | Ozempic | Pre-filled, weekly dose |
| Semaglutide 2.4 mg | Wegovy | Pre-filled, weekly dose |
| Liraglutide 1.2 mg/1.8 mg | Victoza | Pre-filled, daily dose |
| Liraglutide 3 mg | Saxenda | Pre-filled, daily dose |
| Tirzepatide | Mounjaro | Pre-filled, weekly dose |
| Dulaglutide | Trulicity | Pre-filled, weekly dose |
All these pens work on the same basic principle: attach a needle, dial your dose, inject, and remove the needle.
Essential supplies:
Never reuse needles. A used needle becomes blunt, barbed, and carries infection risk. Each injection should use a new needle.
When using a pen for the first time, you must prime it to remove air bubbles and confirm the pen is working:
On subsequent uses: Priming is not required every time — only for first use and if the pen has been dropped or stored incorrectly.
GLP-1 medications are subcutaneous injections — meaning they go into the fatty tissue just under the skin, not into a muscle or a vein.
Approved injection sites:
Abdomen (preferred): 2–3 finger-widths away from the navel. Avoid the navel itself and any scar tissue. This is the fastest-absorbing site.
Outer thigh: The outer, middle portion of the upper thigh. This is a convenient site for self-injection.
Upper arm (back): The outer back of the upper arm. This site is harder to reach for self-injection — easier if a family member or caregiver assists.
Rotation is essential. Never inject in the same spot twice in a row. Rotate systematically — for example, move 2–3 cm from the previous site each time. Repeated injections at the same site cause lipohypertrophy (fatty lumps under the skin) that impair absorption.
Avoid these areas:
Wipe the injection site with an alcohol swab in a circular motion. Allow it to dry completely before injecting — at least 10–15 seconds. Injecting into wet alcohol stings.
In India: Sharps containers (BD Safe-Clip, various brands) are available at pharmacies for ₹50–200. Alternatively, use a thick-walled plastic bottle with a secure lid. Local pharmacies and hospitals often have sharps disposal programmes — check with yours.
Incorrect storage is one of the most common — and costly — mistakes Indian users make.
| Status | Storage | Temperature | Duration |
|---|---|---|---|
| Unopened pen | Refrigerator (not freezer) | 2–8°C | Until expiry date |
| In-use pen (opened) | Room temperature | Below 30°C | 28–56 days (varies by pen) |
| Do not | Freeze | — | Freezing destroys the medication |
| Do not | Direct sunlight | — | Degrades protein structure |
India-specific challenges:
| Mistake | Problem | Fix |
|---|---|---|
| Injecting cold medication | Stings, poor absorption | Remove from fridge 30 min before |
| Reusing needles | Pain, infection, bent tips | New needle every time |
| Not holding needle for 6–10 sec | Partial dose delivery | Count to 10 before withdrawing |
| Always injecting same spot | Lipohypertrophy, poor absorption | Rotate systematically |
| Injecting into muscle | Pain, faster/erratic absorption | Pinch skin, ensure subcutaneous |
| Not priming new pen | Air bubble in first dose | Always prime a new pen |
| Leaving pen in hot car | Medication degradation | Keep in insulated pouch |
Contact your doctor or pharmacist if:
Q: Does the injection hurt?
It should not hurt much at all. A 4 mm needle with 32 gauge diameter is very thin — most users describe it as a tiny prick or nothing at all. If it hurts, you may be injecting into muscle (try pinching more skin) or the needle may be reused (replace it).
Q: What if I see blood after injecting?
A small drop of blood is common and harmless — you have nicked a small capillary. Press gently with clean cotton. It does not affect the dose.
Q: Can I inject through clothing?
This is possible in theory but not recommended — you cannot confirm site cleanliness or pinch depth through clothing.
Q: My pen feels empty but the dose selector says I have doses left. What happened?
This usually means the pen was not primed correctly, or air bubbles caused a partial dose. Do not re-inject without consulting your pharmacist — you risk a double dose.
