linzess weight gain
39 Replies RSS
I was just prescribed Linzess for my IBS. I am wondering if others on this medicine have experienced wieght gain? ## Actually, since it usually causes gastrointestinal side effects, including diarrhea, it's usually known to cause the opposite problem of weight loss. You should also be informed that some people develop serve, ongoing diarrhea, so you need to watch out for that and contact your doctor if it happens. Learn more Linzess details here. Is there anything else I can help with? ## I've gained 4 pounds in 3 days since I started taking Linzess. I am on weight watchers so I count points so I know it is not my food intake. I don't usually fluctuate in pounds so I think it's the new meds. I am still taking Miralax but it doesn't seem like either are working. I loo...

I have tried taking Linzess as needed and everyday. My experience was more often used less lt will works. Taking a break from your Linzess just for one day can make it work better. But need to use fiber drink or stool softener in place of . Do not eat bananas or any food that will cause constipation. Drink 100% pure apple juice and orange juice high pulp and fresh oranges . Also eat activia yogurts with fiber one everyday will help .

Linzess stopped working
3 Replies RSS
I have been on the 145 dose of Linzess for several years now, and it was like a miracle drug. No side effects, and for the first time in 30 years, regular BMs. The past few months have not been so great, though. Constipation, bloating and cramps have returned. I saw my Gastro a few weeks ago, and she upped my dosage to the 290. No change. Has anyone else experienced anything similar? So frustrating! ## Unfortunately, many people have reported the same experience, though the amount of time have varied. Are you making sure to take it with a full glass of water, at least half an hour, before eating or drinking anything else, as directed by the FDA? The bloating and cramps can be side effects of this medication, but it usually causes diarrhea, rather than constipation. Are you on any other ...

Linzess Allergy

I've been on Linzess for constipation for two weeks. While it has only produced one bowel movement during this time, I was still hopeful. However, I woke up on a Wednesday with a swollen face and a bump in my eyebrow. I thought I had gotten bitten by something and didn't attribute it to the Linzess. Took Benadryl but didn't get any relief. I woke up with my eyes swollen almost shut on both Thursday and Friday morning and the bump in my eyebrow began to itch. By Saturday morning when I awoke to a swollen face and eyes again, I knew it was the Linzess. I am bummed since I was so hopeful that the Linzess would help me with my constipation. ## Oh wow! I am so very sorry about what happened. Did you consult your doctor? Has swelling gone away, yet? It is always possible to find o...

Can linzess be taken as needed. My antidepressant causes constipation? ## Hello, Jill! How are you? Some people do take it that way, depending on how it works best for them. There is no harm in trying it that way, if your doctor approves of your doing so. The FDA lists its typical side effects as possibly including nausea, dizziness, bloating, stomach pain and diarrhea. However, have you tried just using fiber supplements?

Linzess, and heart problems
2 Replies RSS
I have been on Linzess since August 2015. By February 2016 I began having heart problems, short of breath, pounding, racing, and palpatating. I have seen a cardiologist, and had a echo cardiogram that showed problems. I went for a heart cath, but only had minminal blockage. I wore a holter heart moinitor for 24 hours, and there was many instances of pounding spontaneous rapid increase in my heart rate, which is what I had been experiencing. Additionally, my lips, tongue, and nose begin to feel tinglely, and numb feeling. I was put on heart meds, and they helped for a bit, but are not working now. Has anyone else experienced heart problems with linzess as well? ## Hello, Esther! How are you? The FDA doesn't list such issues as being among the known side effects for this medication, t...

how good does liness clean colon

Can you tell me does liness clean your whole colon? Are how much cleaning do you get y us Iiness ## Since the effects of any medication tend to vary for each individual, I think it may ultimately be best to work closely with your doctor on finding a safe and effective dosing regimen. Taking it in close proximity to food is something that might also affect how well it cleans. I'd recommend browsing through some of the related Linzess discussion broads here in order to get a better idea of what results are being reported. According to, Linzess is said to work by increasing the motion of food and waste through the stomach / G.I. tract as well as by blocking pain signals - but it goes without saying that the amount of movement or cleansing taking place can unfortunately only be ...

Please respond ## @KR, Sorry to hear about your condition. If you plan on taking an extra laxative medication along with Linzess, I would encourage you to talk with your doctor first just to play it safe with the dosing. However there are other home remedies such as Apple Cider Vinegar and Epsom Salt that might make for good alternatives. Have you also considered taking any probiotics or digestive enzymes to help better metabolize cer...

On Linzess for a week, NOT "Working" - HELP!
14 Replies RSS
Hi all! I'm new here, but not new to constipation... However, I only got my first *prescription* medication to treat it a week ago when my new PCP finally related enough to my digestive woes and the frustration that comes from years of living through the futile cycle of Miralax, MoM bombs, evil teas, and throwing my hands in the air. She gave me samples of Linzess (low and high dose) and thoroughly educated me on how to take it properly, along with a fair warning to remain near the bathroom those first few days. Honestly, I was pumped! And I know beyond a shadow of a doubt I've taken, and stored, this medicine correctly because I was all in on making this work, as gruesome as those first days might be. But alas, radio silence. I started with the low dose a week ago (a Wednesday)...
