Pramlintide nausea and hypo risk, how do you time it with meals?

Posted by tracker_jade in Safety & Side Effects - 5 points, 6 comments.

Anecdotally I keep seeing people talk about pramlintide for appetite suppression but nobody mentions how rough the nausea can be early on. A friend of mine tried it before meals and said the first week was pretty miserable, like couldn't finish a small meal level of fullness. That matches what I'd expect from the gastric emptying slowdown but I'm curious how long it usually takes to settle out.

The bigger thing I wanna ask about is the hypoglycemia risk. The profile says it's used alongside insulin in diabetes settings, which makes sense because amylin and insulin work together. But people using it off-label for appetite control probably aren't on insulin. Does that lower the hypo risk significantly, or can pramlintide still drop glucose enough on its own to be a problem? The glucagon suppression after meals seems like it could cause issues even without exogenous insulin if someone is already prone to lows.

If anyone here has used it, did you notice any glucose crashes or just the nausea and fullness? Did you adjust meal timing or macro composition to deal with it? Just trying to get a sense of what people actually experienced vs the clinical use context.

• early_dad: Haven't used pramlintide myself but I've looked at the amylin physiology a fair bit. The hypo risk without insulin should be lower for sure, since the main danger in the clinical setting is stacking it with exogenous insulin and getting a mismatch. But you're right that the glucagon suppression piece isn't nothing. If someone is already trending low or eating very low carb, I could see it being a problem. Did your friend track glucose at all during that first week? Would be interesting to know
• patient_protocol: The glucagon suppression is the piece people skip right over, and it's a real concern if somebody is already running low glycogen or eating keto-ish, because you're blunting one of the main counter-regulatory responses... So even without exogenous insulin you could get a dip that your body can't mount a proper response to. I don't think my friend was tracking glucose, which honestly is the problem with a lot of these anecdotal reports floating around. Could've been dipping into the 60s and just
• nerdy_nomad: Here's a thought: honestly, my own first week on it was pretty rough too, couldn't finish a quarter of a sandwich without feeling like I'd stuffed myself. I didn't track glucose religiously, but I did notice some jittery mornings that I now think might've been lows. The nausea did start easing up around day 10 for me, though it was never totally gone. Has anyone else just powered through the first two weeks and then seen things level out?
• tracker_jade: The jittery mornings thing is exactly what I was worried about. Did you ever actually check a fingerstick on one of those mornings, or was it more just the shaky feeling? Because the glucagon suppression piece makes me think you could genuinely be running low even without insulin on board. Day 10 for nausea easing up is helpful to know though, my friend bailed around day 5 so I had no reference point for whether pushing through was worth it.
• tracker_jade: The keto angle is a good catch, I hadn't thought about that. My friend eats pretty low carb normally so that could've made it worse. The shakiness vs nausea thing is exactly why I'm skeptical of half these anecdotal reports floating around. Nobody's checking anything. Your reply cut off at the nausea timeline, what have you seen on that? Does it actually settle after a week or two or do some people just never tolerate it?
• tracker_jade: She didn't, which is kinda frustrating because that would've answered a lot. She was doing low carb at the time too, so your point about that being a risk factor is actually pretty relevant. She just toughed it out and said the nausea faded after about 10 days but never checked glucose once. Makes me wonder if the low carb piece made the nausea worse too, not just the hypo risk. Did you come across anything on how carb intake affects the gastric emptying slowdown specifically?
