Alka Seltzer (Alker-Seltzer)

Short answer: The brand is Alka-Seltzer - hyphenated, with both words capitalized. Below are quick checks, plenty of wrong/right swaps, and ready rewrites for work, school, and casual use.

Quick answer

Use Alka-Seltzer. Avoid Alka Seltzer, AlkaSeltzer, or Alker-Seltzer.

Official form: Alka-Seltzer
Common wrong forms: Alka Seltzer; AlkaSeltzer; Alker-Seltzer
Rule of thumb: in formal writing (reports, emails, papers) mirror the brand's hyphenation and capitalization

Core explanation: why the hyphen matters

The hyphen reflects the brand's chosen styling and links the two parts-Alka (alkaline) and Seltzer (fizzy)-into one product name. Missing or incorrect hyphenation looks like a typo and can weaken credibility in formal contexts.

Hyphen = official styling and clearer reading
Use the hyphen in headlines, lists, citations, and running text

Hyphenation rules for brand names

There's no universal rule that forces hyphens for every brand. When a brand provides a preferred form, follow it. Major style guides generally recommend using the manufacturer's form in running text.

Check packaging or the brand's materials when possible
In professional writing, mirror punctuation and capitalization
When in doubt, use the hyphenated brand form if that's how the product is styled

Spacing vs. hyphenation: common slips and fixes

Writers usually make three errors: dropping the hyphen, misspelling, or concatenating. Each fix is mechanical: replace the wrong form with Alka-Seltzer.

Alka Seltzer → Alka-Seltzer
Alker-Seltzer → Alka-Seltzer
AlkaSeltzer → Alka-Seltzer

Wrong: I bought Alka Seltzer at the pharmacy.
Right: I bought Alka-Seltzer at the pharmacy.
Wrong: Do you have any Alker-Seltzer?
Right: Do you have any Alka-Seltzer?

Grammar & capitalization: how to treat the name

Treat Alka-Seltzer as a proper noun: capitalize both parts and keep the hyphen. When it modifies another noun, keep the hyphen and capitals: Alka-Seltzer tablets.

Use a generic term (lowercase) if you mean the product class rather than the brand: antacid, effervescent tablet, pain reliever.

Product name: Alka-Seltzer
As modifier: Alka-Seltzer tablets
Generic: antacid, effervescent tablet

Wrong: I found an alka-seltzer tablet in the pantry.
Right: I found an Alka-Seltzer tablet in the pantry.
Wrong: Bring an alka seltzer if you have heartburn.
Right: Bring an Alka-Seltzer if you have heartburn.

Real usage: tone and audience (work, school, casual)

Formal contexts should use Alka-Seltzer. Casual messages often omit the hyphen, but copying the brand form is safe and clearer.

Work: prefer Alka-Seltzer
School: follow the brand form in text; citation styles handle references
Casual: readers accept variants, but the hyphen is correct

Work - Wrong: Please order more Alka Seltzer for the first-aid kit.
Right: Please order more Alka-Seltzer for the first-aid kit.
School - Wrong: The lab used Alka Seltzer to show a CO2 reaction.
Right: The lab used Alka-Seltzer to show a CO2 reaction.
Casual - Wrong: AlkaSeltzer saved my hangover.
Right: Alka-Seltzer saved my hangover.
