Your Fifth Dose of Mounjaro: What the Titration Schedule Looks Like

Mounjaro (tirzepatide) is a once-weekly injectable medicine that works as a dual GIP and GLP-1 receptor agonist. According to the electronic Medicines Compendium, it is typically started at a low dose — commonly 2.5 mg — to allow the body to adjust, with increases guided by the prescriber over several weeks.

Under a standard titration pattern, doses are generally held for around four weeks before any increase is considered. If that pattern is followed, a fifth dose would fall during the second month — often still on the starting dose, or just moving to the next step. However, titration is not one-size-fits-all: some people stay on a given dose for longer if their prescriber decides that is right for them.

The dose range in context

The dose strengths commonly referenced for Mounjaro are 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. The lowest dose Mounjaro uses (2.5 mg) is a starting point, not a therapeutic target — it is intended to help tolerance. The higher end of the range represents what is sometimes called the maximum dose Mounjaro is available in, though not everyone needs or reaches the highest strengths. Your prescriber decides which dose is right for you based on your full clinical picture.

What the fifth dose is not

It is worth being clear: the fifth dose is not a milestone that automatically triggers a dose change, and there is no universal rule about what dose you should be on by this point. If you have questions about where you are in your schedule, the right conversation to have is with your prescriber or doctor.

You may also find it helpful to read about what a maintenance dose on Mounjaro means and how it differs from the titration phase. Some people also ask about a the concept of a "golden dose" on Mounjaro — the point where many people feel the medicine is working well for them.

One of the most practical things you can do across your titration journey — including around your fifth dose and beyond — is keep a clear log of every injection. GLP Trackr's dose logging feature lets you record the date, time, and dose strength for each shot, so you always have an accurate, timestamped record of where you are in your schedule.

This matters more than it might seem. When appointments with your prescriber come around, being able to show exactly when you took each dose, at what strength, and how you felt around each one gives them genuinely useful information. GLP Trackr also lets you log side effects alongside your dose history, so if your fourth or fifth dose brought a change in how you felt — more nausea, less appetite, better tolerance — that pattern is captured and ready to discuss.

Dose reminders are built in too, so a weekly injection does not slip your mind as the routine becomes more established. If you are thinking about the nuances of your schedule — such as approaches like micro-dosing on Mounjaro — having a precise record of what you have taken and when is especially useful context to bring to your prescriber.

Any decision about your dose — whether to stay where you are, increase, or adjust in any way — belongs with your prescriber. GLP Trackr helps you record your journey clearly so those conversations are better informed; it is not a substitute for their guidance. If you experience anything severe, persistent, or worrying at any point in your treatment, contact your healthcare professional promptly.
