Dissolves fast and work quickly

I do not like the taste of these. Please go back to the orginal Alka-Seltzer. I will not buy these any more.

Bought this as Sams doesn't carry the "regular" strength any longer. These tasted terrible and ended up in the trash. Do NOT recommend.

This "extra strength" is bogus because it contains no aspirin as "Original" did for 20+ years. Will return it for a refund.

The original alkaseltzer with aspirin is a wonder formula that just works for multiple ailments. Taking away the aspirin changes this to new antacid product. I bought it by accident and ended up throwing it away.

Always good quality

It’s hard to find the original Alka-Seltzer sometimes. There is nothing better for an upset stomach than this.

I have been using Speedy Alka-Seltzer for years, and it has never failed me. What I like, is there are no aftereffects, other than a couple of burps.

This is the only antacid that calms the the hot lava in the back of my throat that wakes me up at night.

Fast relief for stomach ache due to the presence of excess acid. Sure glad to have it around when you needed it.
