Symptom questions

Side effects, one symptom at a time

Choose a symptom below to read product-label findings and see what our compound summaries include. Product guides keep each brand’s findings separate. Compound summaries cover selected reactions; a missing entry does not prove that a symptom cannot occur.

Does tirzepatide cause constipation?

Listed in 8 of 42 summariesFDA label

The label for tirzepatide lists constipation. See how often people had it in studies of this drug and other GLP-1 medicines.

Does GLP-1 medication cause nausea?

Listed in 13 of 42 summariesFDA label

GLP-1 labels list nausea as a side effect. See when it occurred in studies, how dose changes fit in and which signs need medical help.

Does Mounjaro cause fatigue?

Listed in 6 of 42 summariesFDA label

Mounjaro’s common-reaction table does not list fatigue. Learn why Zepbound’s tiredness figures cannot be used as a Mounjaro rate.

Does GLP-1 medication cause hair loss?

Not listed in these 42 summaries

Wegovy and Zepbound labels list hair loss. See why the product and study matter, and what these reports can tell you about shedding.

Does Ozempic cause muscle loss?

Not listed in these 42 summaries

Semaglutide weight-loss research found a fall in lean mass. Learn why that is not the same as muscle loss or an Ozempic-specific rate.

Does a GLP-1 cause diarrhea?

Listed in 7 of 42 summariesFDA label

Wegovy, Mounjaro and Zepbound list diarrhea as a side effect. Read the study findings, dose-increase pattern and warnings about fluid loss.

Does a GLP-1 cause burping?

Not listed in these 42 summaries

Wegovy and Zepbound labels list burping as eructation. Read the label findings separately from FDA reports and claims about sulfur burps.

Every question against every record

The whole section in one grid. Listed means that record names the symptom itself. Grouped means it only shows up inside a combined figure — stomach problems counted together, for instance. Each symptom page gives the frequency behind every cell, with its source.

Each symptom question in this section against each of the 42 compound guides, showing whether the page names the reaction, carries it inside a grouped figure, or does not carry it.

One symptom or one compound?

Use this section when you have one symptom and want to compare every compound that lists it. Use a compound’s side-effect guide when you want its complete reaction list and warnings. For example, see the full tirzepatide side-effect guide.

For 3 of the 7 symptoms, no compound summary lists a matching reaction. Product labels may contain entries that these summaries omit. See how we judge the evidence in how we source each answer.

More side-effect questions

Want the complete reaction list for one medicine? Start with the FDA-label guides for semaglutide and tirzepatide. Browse the full compound index for all 42 compounds, or use the side-by-side comparisons to compare two.

Trial side-effect tables and reports filed after a drug reaches the market answer different questions. See the reports in what people actually reported.

Need to know how long a symptom may last? No label or trial states a set duration for every person.

Checking a combination? See what not to mix. Missing interaction data does not prove a combination is safe.

Wondering what happens after treatment stops? Three trials measured weight regain after semaglutide or tirzepatide ended.

Open a compound guide for its reaction summary, source links and evidence limits.

The GLP-1 suicide-warning timeline

Why the regulator moved from an open question to a warning-removal request.

What three alcohol trials actually measured

Three randomized semaglutide trials, with the primary and null outcomes kept together.

Tirzepatide and birth control pills

The current four-week instruction after starting and after every dose increase.

Peptide and bacteriostatic-water calculator for any vial

Concentration, units per dose and doses per vial, with the arithmetic printed.

Why nobody can say how long it lasts

No source cited on this site states how long any of these reactions lasts, and that is the answer.

Where the evidence on stopping runs out

Whether stepping down first helps, and what happens on restarting, are named here as unstudied rather than answered.

Every interaction these pages carry

Nothing on it is built by inference: no mechanism, no “probably avoid”, no list assembled from how a drug works.

Burping across all 42 compound guides

None of the sources reviewed lists burping — and that missing answer is shown clearly.
