Antiperspirants for excessive sweating target the apocrine and eccrine sweat glands, which is why they can reduce sweat production rather than just cover odor. They are usually a milder treatment for hyperhidrosis, so many people try them before pills, devices, or procedures. Standard store products do not work well enough for a lot of readers on this site. Deodorants can still help contain odor, but they do not remove the underlying problem.
Which clinical strength antiperspirant is strongest
Aluminum chloride is likely the strongest over the counter ingredient for excessive sweating. Higher concentrations usually have a stronger effect, which is why medical products often rely on it. Drysol contains 20 percent aluminum chloride and anhydrous ethyl alcohol, and it is mostly used for underarm sweating and palmar hyperhidrosis. It can help, but skin irritation is common enough that many people have to adjust how often they use it.
How Drysol, Driclor, and similar products are used
Drysol is usually left on the affected area for about six hours, which is why most people apply it at night and wash it off in the morning. Initial results can be encouraging, but long term results are often less satisfying than people hope. Xertac AC is another medical antiperspirant used for hyperhidrosis, while Odaban, Driclor, and Maxim are also mentioned often but are usually seen as less effective than Drysol. Some treatments also use ethanol, formalin, or tannic acid, although those can irritate the skin too.
When a prescription antiperspirant or medicine may help
Strong antiperspirants work best when applied at night because sweating is often lower then, and palmar hyperhidrosis may respond better when plastic gloves are added. Stronger products mentioned on this site include Drysol, ArmsUp, WhipWetless lotion, Odaban, Mitchum Clear Gel Sport, and gel base AICI. Some people also move on to physician supervised medicines when topical treatment is not enough. Popular drugs mentioned here include Probanthine, Propranolol SR, and Xanax.
