Gas-X (simethicone) for Gas "I was having terrible terrible stomach pains. Couldn’t fall asleep or get comfortable. Couldn’t even stand up straight. My girlfriend was tired of hearing me moan so she suggested I take a Gas X. After about 3-4 minutes the pain started to break up and my bowels were able to move the gas build up out in the form of a fantastic symphony of flatulence. Absolute bowl ringers for about an hour. Not only was it great relief. It was just a great time. Wonder if you can just take this product for fun? I don’t know. But if you have stomach or gas pains. This is the product."

Gas-X (simethicone) for Gas "Just coming off antibiotics for diverticulitus & could not get my gut to settle down. After over a week of severe gas & bloating with no relief in sight the Dr told me to try Gas-x. I took the maximum & for the next 3 hours burped & farted. It was both relieving and intense. I felt like there was a war going on inside of me. Finally things calmed down & I'm greatly relieved."

Gas-X (simethicone) for Gas "This is a lifesaver. I don't use it every day and I only take 1 pill. Max is 2. It relieved it rather quickly! Took it before bed, felt better, and was able to sleep after a whole day of gas and bloating. I should have taken this sooner!"

Gas-X (simethicone) for Gas "For many years, I have not been able to eat out and hardly any restaurant. In either 15 minutes or up to a few hours depending on where I ate, I would get extremely nauseous and have a diarrhea attack, this after I got extreme swelling in my stomach and belly. I just discovered by accident that if when I took`Gas-X strips, I either did not get any symptoms or they were mild. I have been able to add a few good restaurants to places I can eat, (when before it was only at home) Eating at most fast food restaurants is still a no-no due to MSG and similars. Taking them 20 min or so before eating produces the best results. My son found similar results for himself."

"As I tapered my Benzodiazepine dosage down I began having painful cramps/bloating but could not pass gas, or go to the toilet. I found out about "Benzo Belly" a term used to describe stomach discomfort that happens when people withdraw from a benzodiazepine medication. Abdominal pain, bloating and constipation are a main symptom. Taking a simethicone medicine helped ease my intestinal tension. I would recommend this to anyone with a bloating problem. It very often works!"

Gas-X (simethicone) for Gas "I have made major life changes, including frequent exercise and diet. Eating a lot of fruit and vegetables which is causing me to pass a lot of gas a lot of the time. I've started taking GasX to keep from embarrassing my husband and myself. Works well for several hours."

Gas-X (simethicone) for Gas "For the past 4 years, I had what I thought were terrible menstrual cramps, but they were actually gas cramps caused by hormones. I take the softgels the first couple days of my period and it works like a charm. The only issue is that the relief does not last that long."

Gas-X (simethicone) for Gas "I’ve had the most excruciating pain in my upper stomach you can imagine. Pain that made me roll on the floor in near tears for hours. Not realizing it could be gas (as I’m pregnant) I was on the verge of going to the hospital. I tried Gas-X thinking it could possibly be gas that I was suffering from. When I tell you I will never be without this for the rest of my pregnancy. Highly recommend it."

Gas-X Extra Strength (simethicone) for Gas "I was in pain for 4 hours. The pain woke me up out of my sleep. It felt like I was having a heart attack and my stomach was about to blow up all at once. Thank God I found my Gas X Maximum Strength. I took 2 soft gels and waited. I will say within 5 minutes, I felt like I was having a baby again because a big cramp hit me. But then I felt the medicine working. I'm so grateful for this medicine "

Ovol (simethicone) for Gas "Ovol 35mg Gas relief chewable tablets has two main inconveniences. First he is ineffective/very slow to work, so with one tablet I did not notice any difference and the problem persisted. Even when I took another tablet it was not resolved (and this pattern happens every time), so by the time you take the third, you don’t know if it actually works but super slowly or it does not (compared to other brands that work instantaneously from the first tablet). The second annoying issue is that when you chew the tablet some substance similar to bubble gum sticks on the top of your throat, it is a very uncomfortable residue from the tablet, it does not dissolve completely. So in total, I will not recommend this medication nor purchase it again because of his ineffectiveness and the weird substance that it leaves in the mouth."

Gas-X Extra Strength (simethicone) for Gas "I get very bad bloating pains often. Especially when it's almost that time of month and this really helps. I usually end up taking 4 a day on a bad day. The only reason this doesn't get a 10 is because I didn't want y'all to think I'm a robot."

Ovol (simethicone) for Gas "I find Ovol Chewables easy to use and fairly fast-acting. But like one of the other reviewers, I find the gummy reside on the roof of my mouth annoying. I don't recall having this experience with the Ovol Chewables I've used in the past, just with the ones I have used in the past few months."

Gas-X (simethicone) for Gas "I was in extreme pain and I have vasovagal syndrome so I will pass out due to pain triggers (menstrual cycle, seeing blood, abdominal pain, child birth, anxiety, etc) I didn't know what else to do I used a heating pad, a hot bath, bicycle with my legs in the air thing, all the above. I was so nauseous and having hot flashes feeling faint and could not toot AT ALL. And as SOON as I took the Gas-X I'm talking MINUTES later I was completely fine!!!! Miracle MUST have. U ONLY NEED A FEW MINS TO GET THAT RELIEF. Doesn't have to be an everyday thing for it to work!"

For Gas "I deal with severe IBS on an almost daily basis, and most brands of simethicone help a lot when it comes to relieving gas. A word of warning however - be sure to read the inactive ingredients list! Some brands contain sorbital, which can cause painful reactions in many IBS sufferers, including gas! Gas-X uses sorbitol and mannitol in some of its formulations, so choose carefully."

Ovol (simethicone) for Gas "I used Ovoal Ultra Strength (180mg tablet) chewables. After chewing, there is residue left that is like chewing gum and sticks to the upper palette. I am not sure if I should swallow it or spit it out. But it does not seem right to swallow that chewing gum substance. I called the pharmacist and they have no idea at all. I called Church and Dwight the company that makes Ovol, and they said it should just turn to powder when we chew it. They are not aware of the pill turning to chewing gum and having a residue paste after. It seems like none of the pharmacists or even or manufacturing pharmaceutical company know about this or have the direct experience. I think this really needs to be sorted out so that we consumers really understand what we should expect."

For Gas "I had gall bladder removed not long ago. Terrible bloating and gas pains. I buy the cheapest brand of simethicone that I can find and it works wonders! I usually take two and the bloat is gone in several hours. What's funny to me is reading what people have written about farting. Hahaha. How else would a person pass gas! My doctor doesn't recommend 4 pills per day but an occasional 2 will be fine!"

For Gas "I had a lot of bloating/belching after dinner tonite. Was uncomfortable, felt nauseous. Searched my medicine cabinet and found an almost expired pack of chewable gas-x tablets. Could literally feel it working to settle down my stomach and had less bloating within minutes. Maybe I just got lucky but this really seemed to do the trick."

For Gas "Didn’t work at all for me. I had severe period cramps and gas pains. I took 3 200mg Advil and it stopped the uterus contractions but it didn’t help the gas pain. Took a Phazyme afterwards to help with gas and I’ve never been in so much pain in my life. I was bed-ridden all day. It made me feel constipated."
