Senna "After all the horrible reviews here, I never would have tried Senokot if I had read them first! However, I have had the opposite experience, they don't work for me at all. Nothing happens. Nada. I tried 2 tablets before bed, and I passed a tiny stool in the morning. The next time I used them, I took 4. Again, I took them before bed, and the following day, 14 hours later, I passed a minuscule stool. I had been using Dulcolax, but they are quite strong for me, and you wouldn't want to be far from a toilet for the entire day, and I found myself quite drained of energy, but at least they did the job. Won't be using Senokot again."

For Constipation "I took Ex-Lax with senna to induce a BM due to unrelenting constipation. The result? My mind was sped up, I felt faint with a panic attack feeling, stood in the dark, praying to get back to normal. BM? Yeah, a very small BM, wasn't worth the bad trip. I'll never use anything with senna again!"

For Constipation "Had an awful stomach bug which caused me surprisingly to become very constipated. I could just about manage to pass a very small bowel movement but not enough to feel fully relieved. I took a senna tablet at about 11 pm because I had awful stomach pain. At about 1 pm, I started to have the urge to go to the toilet. Senna is fabulous!"

Senna for Constipation "This works like a charm. I feel really bad for those who it doesn't work for or causes extreme pain. Seems those of us who suffer from chronic constipation, it really works well. I never have pain, works quick, and clears everything right out. I never have any pain while using this product, however, I do have to go to the bathroom 5-6 times after using it for the next few hours. But when I take this, it's because I really need it. So, I love it."

Senna for Constipation "It’s hit or miss. Usually 2 regular strength will cause something in 24 hours. No cramps, no feeling of movement, just a sudden urge to go. It’ll be large and hard. One poop, no follow-ups, no diarrhea. Currently I’m on 30ml of lactulose twice daily, and Senokot every 3rd day to get it out. The lactulose doesn’t do anything but make my every third day poop not as hard as a rock."

For Constipation "I just took a package of Senna laxative back to the drugstore and told them I felt like it almost killed me, and there should be a big warning on the package. After taking as prescribed at night with lots of water, I woke with extreme cramping and nausea. I crawled to the bathroom, where I lay on the floor because I was passing out. It was coming out of both ends, and I had no control. I was sweating profusely, and my heart was pounding in my chest. It was several hours before the feeling passed. It was terrifying, and I get the same reaction from any senna-based laxative. I don’t know why there isn’t a warning about this on senna medication."

For Constipation "Do not take this. I took one pill around 11 PM. Then around 1 PM the next day, I was vomiting non-stop and had severe abdominal pain. I have not been able to eat and am finding the easiest things to be impossible. I’m fatigued, weak, and still have bad cramping. The cramping is so bad that I can’t even stand up straight. It totally ruined my day. I hope tomorrow is better, but I will definitely be throwing this product in the garbage. Avoid."

Senna for Constipation "This product works really well. I almost never get constipated, but I have quit smoking, and I was having this side effect. I had tried Dulcolax before, and it was a terrible experience with terrible cramps and urgent diarrhea. This medication was recommended by a friend. I was hesitant to try it, but I was very uncomfortable and desperate. I also had hemorrhoids due to the constipation that were healing, and I was scared they would return. I took 2 pills at 9 p.m., and at 4:30 a.m., I woke up to have a BM. The first one was normal, and I had to go about 4 times afterward, and it was diarrhea. I didn't have any cramping or discomfort. I just needed to be near a washroom for about 2 hours after it started working. I feel so much better now. No more bloating, the BMs didn't hurt my hemorrhoids, and I feel like myself again."

Senna for Constipation "I took two at 8 pm and then the next morning... nothing at all happened, just a few stomach grumbles. I think I may have to increase the dosage today, as it didn't work. I've had laxatives that work in 8 hours, really quick and really effective with 1/2 pills. However, this one you need to slowly build up the intake of tablets every day -.- which is a bother."

Senna for Constipation "Was constipated for a few days, so took 2 Senokot, and nothing, so, 2 more a few hours later, still nothing. In desperation, took 2 more. This worked finally, with not too much pain, BUT now have had stomach tremors for the last few days, to the point of I've resorted to heat packs, etc. After doing research, have discovered this can be one of the rare side effects. Just an awful feeling, so never again will I take these."

Senna for Constipation "I took 1 tablet before bed for constipation as advised by a pharmacist (I’d had diarrhea on Saturday, then hadn’t been at all for 5 days - usually I’m every 2-3 days). The Senokot made me have a bowel movement the next day, around 14 hours after I had 1 tablet. Then I went again a couple of hours later. I started to feel quite sick at this point, really uneasy stomach, not much of an appetite. I still ate lunch and snacks as normal and didn’t feel like I needed to be sick - just crazy nausea. Then a few hours later, I went again, but it was more like diarrhea - then I felt VERY sick. I had to go to a pharmacy again for nausea relief (I was taking a flight to go on holiday, so I wasn’t going to wait for it to pass naturally!) - she gave me Pepto Bismol in liquid form instead of tablets - it worked like a dream and I’ve felt fine ever since. ADVICE: If you get the nausea (it was really bad) - definitely get Pepto Bismol to counteract it! So worth it."

For Constipation "Senna works every time! It can take 12 hours to a day to work, but it works with no side effects except some cramping, which is good. I take 2 chewables for the first dose, then take 1 more tablet when I start to feel cramping with no bathroom luck, usually works an hour later. To make it more effective, stay hydrated with warm liquids, massage your abdomen, and place a stool under your feet when using the bathroom to help you go better. Natural and safe!"

Senna for Constipation "For the second time in a few months, I'm getting hives an hour or so after taking this medication. The first time around, they were really bad. The second time, as soon as I got the itching and a few hives, I took an antihistamine that helped with the hives."

Senna for Constipation "This product worked absolute wonders for me. I was constipated for weeks, and then finally, this morning, I birthed an actual python out of my body. I would be on an Ex-Lax commercial if given the opportunity. Sweet relief."

For Constipation "Drugs spook me, so I try to be as 'natural' as possible. I've tried senna, but don't like it. What works for me? Prune juice! About 10-12 big gulps of prune juice - a couple of hours later, 'it's time to go' - and I mean go! It's amazing how well it works for me."

For Constipation "I hadn't been to the bathroom for almost one week. My stomach was rock hard, and I felt so sick. I took three senna tablets at 7 pm. At around 2 am, I woke up with the most horrible stomach cramps and gas. I lay on my left side with a cushion pressing into my cramping stomach until 5 am. I had the most intense urge to poo. I barely made it to the toilet. I had explosive diarrhea. It was the most painful stomach cramps I have ever had, I sat on the toilet for an hour, bent over my legs, crying from the pain. I still feel sick and crampy at 6 pm. It did get the poo out, but it was horrifically painful."

Senna for Constipation "Senokot is an unpredictable laxative. I take pain pills for chronic pain. For years, I took magnesium oxide, which worked like a charm. However, I had to keep adjusting the dose, and it finally stopped working altogether. After trying other laxatives unsuccessfully, I tried Senokot. Began with 2 pills: nothing. 3 pills: nothing. I finally took 4 pills, and the next day, excruciating cramps & went 4 times. Stools were not soft, and I had to strain despite taking stool softeners (these have never worked alone, but I read that taken with Senokot helped). At my wit's end because nothing aside from enemas works. I eat prunes, plenty of fruit, dried figs, & tons of vegetables. I can't take the cramping side effect, which I never had with magnesium oxide."

Senna for Constipation "Works well for me, usually 1 max strength tablet is enough, but I’ve taken 2 in one day before, morning and evening. I did get some stomach cramps from the double dose, but not bad enough to stop me from doing normal daily things. Personally, I prefer Senokot to Dulcolax, that was the one that gave me really painful cramps, so I have stuck with Senokot!"

Senna for Constipation "I have constipation regularly. Milk of magnesia gives me terrible cramps and makes me have nausea. Usually no BM. Miralax takes 3 days to work on me. Bisacodyl tablets react the same as milk of magnesia, except with horrible gas. Senna, I have normal cramping before a BM, it usually takes 8 hours to work. Very pleased."

Senna for Constipation "The first time I took Senokot, it made me have a bowel movement within an hour but was okay. The second time I took one, all hell broke loose. I don't know if having IBS plays a part in it, but I get severely constipated and don't have bowel movements for up to a week sometimes. But I took the Senokot, and once again, within an hour, I was on the toilet. I had a bowel movement. And then another. And another. In total, 10 times since I've taken the pill over the course of the day. I have felt lightheaded all day and feel as though I am going to pass out every time I make my way to the toilet. I have barely eaten anything today just because my stomach is bothering me so much. Now trying to sleep, but paranoid that I might end up needing to go for another bowel movement soon as my stomach is making some crazy noises. I would rather be constipated, the side effects are not worth it. I have been lying in bed all day, unable to do anything. At least when I am constipated, I can still go on with my day to day."

Senna for Constipation "I actually would recommend this product when you feel uncomfortably bloated. I took/take one tablet at night if I feel the need with a mixed herbal tea. The next morning, you do need a bowel movement, and you do get some cramping, but if you don’t take more than you need, it’s bearable and relieving. Heed the warnings, though, if you think you might not tolerate this or you’re tempted to take more than you should - DON’T. You will be on the loo on and off with severe stomach cramping for hours and hours. I took 2 one night, and I could barely walk around town the next day, I was in so much pain with my stomach and feeling sick. Can have really horrible side effects, but if it’s needed, it’s needed."

For Constipation "I'd rather stay constipated than use this again! Used Coloxyl with Senna to treat 4-day constipation due to a viral stomach bug. Supposed to work in 8 hours, but 4 hours after taking 1 tablet, I got bad stomach pains, nausea, and a general unwell feeling. Lasted all night and into the next morning."

Senna for Constipation "Worked very well. I’m on the toilet now. It didn’t work in 6-12 hours, it worked in 5, and now I’m going. My stomach hurt so bad. I chose this one at my local Walgreens. I also drank a little of the MiraLax powder, that made it work faster, in my opinion."

Senna for Constipation "I took Senokot, and it took about 9-10 hours for mine to start to work. When it did work, the experience itself is not the most comfortable, given slight cramps and a BM with a soft but foreign feeling consistency. However, it did get the job done, and I do not regret choosing this option. Would only recommend if constipation lasts for more than a couple of days, else, don’t put yourself through discomfort for nothing."
