Tirzepatide (brand names: Zepbound and Mounjaro) is a weekly subcutaneous injection used for managing type 2 diabetes and promoting weight loss. Doctors mostly begin with a low starting dose and gradually increase it to help patients adjust to the medication. Maintaining a consistent weekly schedule is very important. Choose a day that works well for your routine.
You can get the injection at any time of day, with or without food. The shot is given under the skin on your thigh, stomach, or upper arm. Your doctor will decide the right amount for you. If you forget a dose, you can take it up to four days later.
If it’s been more than four days, skip the missed dose and take your next one on your usual day. As a new user, you must follow what your doctor prescribes, but here is the standard method of using it, along with dosage and the schedule.
How To Take Tirzepatide
Tirzepatide is taken once a week, on the same day each week. Choose a consistent day that fits your routine and lifestyle. It can be taken at any time of day, with or without food.
If you miss a dose:
- Take it as soon as possible within 4 days
- If more than 4 days have passed, skip the missed dose and resume your usual schedule
Tirzepatide Dosage and Schedule
Stage | Dose | Duration |
Starting Dose | 2.5 mg, once weekly | First 4 weeks |
Increased Dose | 5 mg weekly | After week 4 |
Further Increases | 7.5 mg up to 15 mg | Every 4 weeks, as tolerated |
Never change your dosage without speaking to your doctor. Dosage adjustments are based on how well the medication is working and any side effects you experience.
How To Inject Tirzepatide
Tirzepatide is given as a subcutaneous injection (under the skin) using a pre-filled, single-use injection pen. Giving yourself a tirzepatide shot is easier than you might think.
The medicine comes in a special pen that does most of the work for you. You don’t need to fill needles or measure doses. The pen is ready to use right out of the box. Most people feel nervous about their first shot, but it gets easier each time
- Clean your hands thoroughly before handling the medication.
- Inspect the solution to ensure it appears transparent and free of particles.
- Select your injection location (abdomen, upper leg, or upper arm).
- Gently grasp the skin and insert the needle straight down.
- Push the plunger steadily until you hear an audible click.
- Place the used needle in a proper medical waste bin.
Available Doses
Your doctor will start you on the lowest dose and slowly make it higher every few weeks. This helps your body get used to the medicine without too many side effects. Most people like to stay on their dose for at least four weeks before changing. Never change your dose without asking your doctor first, even if you think you need more or less medicine.
