What Are Gas X Maximum Strength Gas Relief Softgels?
Gas X Maximum Strength softgels are an antigas medicine with 250 mg of simethicone per softgel. Haleon makes them for adults and children 12 years and older. Each softgel targets gas pressure, bloating, and discomfort in the stomach and intestines.
The brand calls itself the number one doctor recommended antigas brand in America. That claim comes from the manufacturer, not from an independent test. The Maximum Strength line sits above Extra Strength (125 mg) and Ultra Strength (180 mg) in dose.
The softgels have no flavor and come in a box of foil cards. One Amazon summary notes the softgels are easy to swallow and easy to remove from the foil.
How Does Maximum Strength Compare to Other Gas-X Strengths?
Gas-X sells several strengths. Extra Strength holds 125 mg of simethicone, Ultra Strength holds 180 mg, and Maximum Strength holds 250 mg. Ultimate Strength softgels go to 500 mg. The brand also sells chewables for people who dislike softgels.
Gas-X softgel strengths:
| Product | Simethicone |
|---|---|
| Extra Strength Softgels | 125 mg |
| Ultra Strength Softgels | 180 mg |
| Maximum Strength Softgels | 250 mg |
| Ultimate Strength Softgels | 500 mg |
How Do Gas X Maximum Strength Softgels Work?
The softgels work by breaking up gas bubbles in the stomach and intestines. Simethicone is a gas relief agent. It changes the surface tension of the bubbles so they merge and release. Your body then clears the gas naturally.
Simethicone works fast and does not get absorbed into the bloodstream, according to the manufacturer. Gas-X says Maximum Strength starts to provide relief within minutes. Why does that matter? It means the medicine acts where the gas sits.
Antacids work differently. They neutralize stomach acid, while simethicone targets trapped gas. For gas pressure and bloating, simethicone is the more direct tool.
How Do You Take Gas X Maximum Strength Softgels?
Adults and children 12 and older swallow one or two softgels with water as needed. Take them after meals and at bedtime. Do not exceed two softgels in 24 hours unless a physician advises it.
Dosing steps from the label:
- Swallow one or two softgels with water after a meal
- Repeat at bedtime only if gas is still a problem
- Stay at or below two softgels in 24 hours
- Ask a doctor before going above that limit
What Is in Gas X Maximum Strength Softgels?
Each softgel contains 250 mg of simethicone as its only active ingredient. The inactive ingredients are D&C red no. 33, FD&C blue no. 1, gelatin, glycerin, lecithin, purified water, and titanium dioxide. Gelatin means the softgels are not vegetarian.
Inactive ingredients:
- D&C red no. 33 and FD&C blue no. 1 (purple color)
- Gelatin and glycerin (softgel shell)
- Lecithin
- Purified water
- Titanium dioxide
The dyes give the softgel its purple look. People with gelatin or dye sensitivities should read the full Drug Facts label before buying.

Reviews lean strongly positive across retail and drug review sites. Drugs.com lists an average of 8.2 out of 10 from 26 reviews for Gas-X, with 77 percent positive and 15 percent negative. Sam's Club shows 4.7 out of 5 on Gas-X Extra Strength.

What Are the Side Effects of Gas X Maximum Strength Softgels?
Simethicone has a mild safety profile because it is not absorbed into the bloodstream. Gas-X says to use the products only as directed. Reviews mention some side effects, but the research we found did not list specific ones for this product.
Our team advises checking the full Drug Facts label. If you are unsure the product fits you, the manufacturer says to speak with your doctor or a pharmacist.
Who Should Check With a Doctor First?
Anyone unsure about taking Gas-X should ask a doctor or pharmacist. That includes people on several medicines, people with ongoing gas or stomach pain, and anyone wanting more than two softgels in 24 hours. Keep the box away from children.
Is Gas X Maximum Strength Softgels Safe After the 2026 Recall?
Yes. The June 2026 recall covers Gas-X Extra Strength Softgels 125 mg, not Maximum Strength. On June 4, 2026, Haleon recalled four lots of the 120 count and 72 count Extra Strength boxes distributed around April 13, 2026.
The cause was possible contamination with a diluted propylene glycol based coolant from a packaging machine leak. The notice says it could cause nausea, vomiting, abdominal pain, and diarrhea. Express Scripts noted no adverse events were reported.
Gas-X still shows the recall notice on its Maximum Strength page. If you hold an Extra Strength box bought on or after April 13, 2026, check the lot number and call Haleon at 1-800-245-1040.
Is Gas-X a Legit Brand?
Yes. Gas-X is a long-running brand from Haleon, sold at Amazon, Walmart, Sam's Club, and pharmacies. The recall shows the company issued a public notice and a consumer hotline, which is how a legitimate manufacturer should respond.
How Much Do Gas X Maximum Strength Softgels Cost?
The 30 count box costs about $10.98 on Amazon, or $0.37 per softgel. Prices change by store and pack size, and Gas-X also sells a 50 count size. Check current pricing before you buy.
Coupons help. The Gas-X site offers a $1 off coupon after you sign up with Haleon myHealth. Free Amazon delivery applies on orders over $35.
Is Gas X Maximum Strength Worth the Price?
Yes, for people who get regular gas relief from it. At about 37 cents per softgel, one dose of two costs about 74 cents. Some Amazon buyers say it is not worth the extra cost over lower strengths, so try Extra Strength first if your gas is mild.
