Gas-X (simethicone) for Gas "I was having 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 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 bowel 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 "I used to experience severe chest pains that would move into my back until and think I was having a heart attack but after I found Gas-X, it was like a lifesaver. The pain was just wind - but man, that can hurt."

Gas-X (simethicone) for Gas "Just coming off antibiotics for diverticulitis and could not get my gut to settle down. After over a week of severe gas and bloating with no relief in sight, the doctor told me to try Gas-X. I took the maximum dose and for the next 3 hours, burped and farted. It was both relieving and intense. I felt like there was a war going on inside of me. Finally things calmed down and 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 at 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 happened after I got extreme swelling in my stomach and belly. I just discovered by accident that if 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 the 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 minutes or so before eating produces the best results. My son found similar results for himself."

Gas-X (simethicone) for Gas "For years I suffered with horrible gas pains. Someone suggested Gas-X. Tried it and in seconds the pain was gone. It was like a miracle. Just wish I had known how effective it was long ago. I keep boxes of it in both bathrooms."

Gas-X (simethicone) for Gas "Tired of waking up with gut pain and bloated abdomen. Finally tried simethicone to see if it would help. Next morning was the first morning in several months that I woke without pain and bloating (normal!). I wish I would have started using this product months ago!"

Gas-X (simethicone) for Gas "I have many horrible experiences of gas, bloating, headache, vomiting - pure life of misery. All this happens if lunch or breakfast is 1/2 hour late. No doctor could relieve my misery. I walked into a pharmacy in pure desperation and picked up the first item that said gas relief. I took one before I left the pharmacy, and in minutes, I felt at ease. Why didn't I take this before? I'm happy I found it now. I took only my first two but will continue to use it."

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 Gas-X to keep from embarrassing my husband and myself. Works well for several hours."

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 (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 soft gels the first couple of days of my period, and it works like a charm. The only issue is that the relief does not last that long."

"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 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."

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, childbirth, anxiety, etc.). I didn't know what else to do. I used a heating pad, a hot bath, the 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!"

Ovol (simethicone) for Gas "Ovol 35 mg gas relief chewable tablets have two main inconveniences. First, it 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, and it does not dissolve completely. So in total, I will not recommend this medication nor purchase it again because of its ineffectiveness and the weird substance that it leaves in the mouth."

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 residue 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."

Ovol (simethicone) for Gas "I used Ovol Ultra Strength (180 mg tablet) chewables. After chewing, there is residue left that is like chewing gum and sticks to the upper palate. 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 the manufacturing pharmaceutical company know about this or have direct experience. I think this really needs to be sorted out so that we consumers really understand what we should expect."

Phazyme Maximum Strength (simethicone) for Functional Gastric Disorder "I have Crohn's/IBD and often am bloated from gas buildup and have gas pain. I started taking Phazyme, the soft gels maximum strength. Two a day after dinner, since the evening is when I feel the most pain. After about five minutes, it all came out and I felt relieved. I highly recommend it to anyone with Crohn's."

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 sorbitol, 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."

For Gas "I had my gallbladder 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 four pills per day, but an occasional two will be fine!"
