Retatrutide Side Effects

Side Effects

Retatrutide Side Effects

A triple agonist adds glucagon to the familiar two, and glucagon brings something the other drugs in this class do not: an effect on heart rate that trial protocols monitor and no consumer app will ever prompt you about.

Orforglipron Side Effects

Side Effects

Orforglipron Side Effects

A daily GLP-1 pill that is not a peptide — which removes the fasting window that makes oral semaglutide so awkward, and keeps the gastrointestinal profile that defines the whole class.

The Best Reflux Relief on a GLP-1

The Best Reflux Relief on a GLP-1

Delayed gastric emptying pushes stomach contents upward, which is why reflux that was occasional becomes nightly. Seven options ranked — and an argument for not settling into a proton pump inhibitor for two years without asking why.

Foundayo Side Effects

Side Effects

Foundayo Side Effects

The side-effect pattern of a GLP-1 is largely a property of the class, and most of what determines whether you get through the first three months is the same regardless of which one you were prescribed. Here is the part that generalises.

Tirzepatide Side Effects

Side Effects

Tirzepatide Side Effects

A dual agonist that produces the largest average weight loss in the class — which means more of everything, including the effects nobody warns you about. And one interaction whose clock restarts every single time you go up a dose.

Zepbound Side Effects

Side Effects

Zepbound Side Effects

Tirzepatide at obesity doses, in a population that increasingly includes people treated for sleep apnea. Which raises a question the trials answer better than most people realise: what happens to daytime function while your gut is adjusting.

Mounjaro Side Effects

Side Effects

Mounjaro Side Effects

Tirzepatide licensed for type 2 diabetes, which puts two things at the front that the obesity label does not: what happens when it meets your insulin, and a contraceptive interaction whose clock restarts every time you go up a dose.

Oral Wegovy Side Effects

Side Effects

Oral Wegovy Side Effects

An oral GLP-1 removes the injection and adds a variable nobody expects: how much drug you absorb depends on how you took the tablet. Which means an unpredictable week is often a dosing-conditions problem rather than a drug problem.

The Side Effects Nobody Preps You For

Side Effects

The Side Effects Nobody Preps You For

Nausea gets all the attention. It is not usually what makes people quit. A practical field guide to the gastrointestinal reality, the genuinely serious risks, and the things that actually help.

Semaglutide Side Effects

Side Effects

Semaglutide Side Effects

One molecule, four delivery routes, and a side-effect profile that is largely the same across all of them — with one important exception. If your semaglutide comes from a compounded vial, the most likely serious problem is not the drug.

Wegovy Side Effects

Side Effects

Wegovy Side Effects

Wegovy titrates to 2.4 mg — the highest semaglutide dose in routine use — through five fixed steps. Which means the side-effect story here is really a story about escalation, and about the one decision you get to make five times.

Ozempic Side Effects

Side Effects

Ozempic Side Effects

The nausea gets all the attention and is rarely what makes people quit. On Ozempic specifically the risk that deserves your attention is different: it is what happens when semaglutide meets the other diabetes drugs you are already taking.
