MOUNJARO FOR WEIGHT LOSS | Week 9 7.5 mg | New Dose, New Symptoms
Patient story
Our summary
Brittany Rose gives her update for the first week on the 7.5 mg dose of Mounjaro, which she describes as very different from her earlier doses. She says she was nervous about the injection because of how the 5 mg dose felt the first time. She lets the pen sit out for about 10 minutes first, and says this helps it hurt less because it is not cold.

What else the video covers
She says she felt fine for roughly the first 24 hours, then developed a jittery, anxious feeling that lasted several days. She stopped taking Phentermine for about four days because she thought it was making things worse, and says that helped a little. She found a Reddit thread where others described the same reaction to 7.5 mg, and some commenters said they needed antidepressants. She messaged her doctor, who she says has heard of this occasionally and suggested giving her body a week or two to adjust. She already takes anti-anxiety medicine and says she felt much better over the last two days.
She also reports a second new symptom: after being constipated for her whole time on Mounjaro, she had diarrhea all week and stopped taking Colace. She says she ate little for several days, then felt hungry for the first time since early November but did not overeat. Her weight loss for the week was 2.2 pounds, bringing her total to 30.2 pounds. She says she told her sister she might not continue if next week felt the same.

Our guides closest to what this video covers, with prices checked weekly.
- Mounjaro dosage chart: the label's schedule, every pen and vial, and what each dose costs
Mounjaro starts at 2.5 mg injected once a week. If more blood sugar control is needed, the dose goes up in 2.5 mg steps after at least four weeks on the current dose, to a maximum of 15 mg a week for adults and 10 mg for children 10 and older. Lilly sells every strength self-pay starting at $499 a month, so on the brand the price does not climb with the dose.
- Mounjaro side effects: the label's numbers by dose, the low blood sugar risk, and how tirzepatide compares at weight-loss doses
On Mounjaro's own label, the common side effects are stomach ones and they rise with the dose: nausea in 12, 15 and 18 percent of people at 5, 10 and 15 mg against 4 percent on placebo, diarrhea 12 to 17 against 9, and any gastrointestinal reaction in 37 to 44 percent against 20. Most of it happens while the dose is being raised and fades. Low blood sugar is rare on Mounjaro alone and is mainly a risk when it is added to insulin or a sulfonylurea. Below: the full table, the rare warnings, and why Zepbound's numbers for the same molecule look higher.
- Mounjaro vs Rybelsus: a weekly shot against a pill Novo is replacing
Mounjaro is tirzepatide, a once-weekly injection; Rybelsus is semaglutide, a once-daily tablet. Both are type 2 diabetes drugs, and they have never been tested against each other. The bigger news for anyone choosing: Novo Nordisk says Rybelsus is being replaced by the Ozempic pill, which needs a new prescription. Paying cash, Mounjaro starts at $499 a month at LillyDirect, and Novo sells the Ozempic pill, not Rybelsus, at $149 to $299 a month.
