Hyperhidrosis · deodorant or antiperspirant?
Deodorants for hyperhidrosis: why the label word matters
Many people with heavy underarm sweat search for a “deodorant.” Dermatologists draw a clear line: deodorants are made to mask or stop odor, and antiperspirants reduce sweating. If wetness is the problem, you are looking for an antiperspirant, and possibly a deodorant alongside it.

Direct answer
Deodorant handles odor. Antiperspirant handles sweat.
The American Academy of Dermatology’s first self-care tip for excessive sweating is to use antiperspirant instead of deodorant: “Antiperspirants help reduce sweating. Deodorants don’t.” (AAD).
Maxim Ulti-Dri is an antiperspirant with 15% aluminum chloride, the maximum FDA allows for that active in OTC antiperspirants (21 CFR 350.10). Maxim Sensitive is listed at 10.8%. Follow the label; individual results vary.
Maxim is not a treatment for menopause hot flashes, night sweats, or whole-body sweating. Those need a clinician.

Why the word “deodorant” trips people up
Cleveland Clinic explains that antiperspirants reduce the amount of sweat while deodorants mask body odor (Cleveland Clinic). Body odor happens when bacteria on the skin come into contact with sweat (Cleveland Clinic: body odor), so the two problems are related, but a deodorant does not change how wet you get. FDA requires a product that reduces sweat to identify itself as an “antiperspirant” on its label (21 CFR 350.50).
What to look for in an antiperspirant for heavy underarm sweat
The word “antiperspirant”
Not “deodorant” alone, and not “aluminum-free.” The International Hyperhidrosis Society notes aluminum-free formulas are less effective at reducing sweat (IHhS).
The active and its strength
Drug Facts lists the active ingredient and percentage. IHhS describes clinical-strength OTC products as having higher concentrations of active than regular formulas.
A routine you can follow
AAD advises bedtime application to dry skin, nightly until sweating is controlled (usually within a few weeks), then usually once or twice a week.
Skin tolerance
If irritation develops, AAD suggests spacing applications, trying a gel formulation, or making sure skin is very dry, and telling your dermatologist. IHhS suggests fragrance-free options for sensitive skin.
Using an antiperspirant and a deodorant together
AAD lists two ways to use both: choose a single product that contains an antiperspirant and a deodorant, or apply a prescription antiperspirant at bedtime and a deodorant when you wake up. Maxim’s own directions use the second pattern: Maxim at night, your normal deodorant in the morning (Maxim directions).
When it may not be “just” sweaty underarms
AAD describes primary hyperhidrosis as usually starting in childhood or adolescence and affecting one or two areas, while secondary hyperhidrosis usually causes heavy sweating over most of the body and is related to a medicine or another medical condition (AAD symptoms). MedlinePlus advises contacting a provider if sweating is prolonged and unexplained, mostly during sleep, or comes with fever, weight loss, chest pain, shortness of breath, or a pounding heartbeat (MedlinePlus).
For the full range of treatments dermatologists use beyond antiperspirants, see Maxim’s excessive sweating page and the AAD treatment guide.
