What is tirzepatide?

Tirzepatide is an injectable drug and one of the latest medications to treat diabetic type 2 diabetes and promote weight loss. It is a component of two brand-name medications, one as a diabetes medication and one as a weight-loss medication. Tirzepatide is an agent that targets two gastrointestinal hormones, GIP and GLP-1, that aid in lowering the blood sugar level, slowing down the process of digestion, decreasing hunger, and increasing food fullness. Due to the dual action, it not only has an effect in regulating the level of glucose in the blood but also can result in a significant loss of weight when used under medical supervision.

Available Tirzepatide Dosage for Weight Loss: A Complete Breakdown

The two drugs, Mounjaro and Zepbound, have the same six doses. The doses are available in a single-dose pen that is prefilled. And one dose is once per week. Therefore, a month’s supply will need four pens.

There are Tirzepatide doses: 

  • 2.5 milligrams per 0.5 milliliters prefilled single-dose pen
  • 5 milligrams per 0.5 milliliters prefilled single-dose pens
  • 7.5 milligrams per 0.5 milliliters prefilled single-dose pens
  • 10 milligrams per 0.5 milliliters prefilled single-dose pens
  • 12.5 milligrams per 0.5 milliliters prefilled single-dose pens
  • 15 milligrams per 0.5 milliliters prefilled single-dose pens

Tirzepatide Injection Tips

  1. Learn how to inject yourself through your healthcare provider, your pharmacist, or by reading the manufacturer’s websites.
  2. Keep a schedule and inject yourself at the same general time on the same day of the week each week. In order to remember, schedule a reminder on your smartphone or watch.
  3. Do not be afraid to inject yourself during eating; tirzepatide may be consumed with or without meals.
  4. It can be injected in the same area, but not the same injection site as insulin. Rotating injection sites helps avoid skin problems.
  5. To facilitate the stability of the medication when traveling, consider using a Mounjaro travel case to store your pens.

Tirzepatide Dosage: From Starting Dose to Maintenance Plan

  • Like other weight loss injections, zepbound is given in a stepwise dosage regimen with the active ingredient tirzepatide.
  •  You begin with a small dosage, such that once your body adapts, you can reduce some of the most common Zepbound side effects, such as nausea, diarrhea, loss of appetite, vomiting, constipation, dyspepsia, and abdominal pain. 
  • You are then to gradually increase your dose by 4 weeks until your maintenance dose. 
  • In the case of Zepbound, the target maintenance dose is usually 15 milligrams. It has been observed in clinical studies that individuals show maximum weight loss at this dose. 
  • The maintenance dose can be reduced to a lower dose, to a minimum of 5 milligrams, and then go up, depending on how you tolerate Zepbound.
  • In the case of Mounjaro, 5, 7.5, 10, 12.5, or 15 milligrams may be used as a maintenance dose. The determination of the final maintenance dose will hinge on both the quantity you require to carry out perfect control of blood sugar and your level of tolerance to the medication.

  • When using Mounjaro, never exceed the suggested dosage that your provider has prescribed, since this could cause difficulties in controlling blood sugar.

  3. In the case that you miss a dose and it was within the last 4 days (96 hours), take a new one when you remember.
  4. However, you may take the missed dose if it is less than 4 days, but in that case, you need not take two doses at a time.

Tirzepatide Overdose: What to Do If You Take Too Much

  1. You can not lose weight fast, and can not manage your diabetes better with additional medication, yet it can give you unnecessary side effects.
  2. It is only possible to use two single-dose prefilled pens too soon or simultaneously and thus end up taking too much.
  1. In case of any reason, you take an overdose of Tizanidine, contact your healthcare provider to seek advice about what to do.
