Alka‑Seltzer Plus Severe Cold & Flu – Citrus Effervescent Tablets
1. First Impressions & Packaging Box design: The carton is bright, with a citrus‑colored stripe that instantly signals the “lemon‑lime” flavor inside. The front panel lists the major symptoms it tackles (nasal & sinus congestion, sneezing, runny nose, cough, sore throat) in large, easy‑to‑read type. Tablet count: 24 tablets per bottle – enough for a full 8‑day course if you take the recommended dosage (two tablets every 4–6 hours, not to exceed four doses per day). Convenience: The bottle is a standard, flip‑top plastic that opens easily but seals tightly enough to keep the tablets dry. I appreciate the small “pop‑up” insert that explains the “plop plop fizz fizz” – the reaction that makes the tablets dissolve quickly. Verdict: The packaging is practical, portable, and clearly communicates what the product does. No frills, but it works. 2. The “Plop Plop Fizz Fizz” Experience Dissolution: Drop two tablets into a glass of water. Within ~30 seconds they start bubbling (the classic Alka‑Seltzer fizz), and within a minute the solution becomes a mildly effervescent, citrus‑tasting drink. Flavor: The citrus flavor is bright but not overpowering. It’s sweetened just enough to mask the medicinal taste without feeling like a sugary soda. For those sensitive to strong menthol or menthol‑like flavors (common in many cold medicines), this is a welcome change. Palatability: I can comfortably drink the whole glass in ~10 seconds. No choking on foam, no lingering after‑taste once the liquid is swallowed. Verdict: The “plop plop fizz fizz” isn’t just a marketing gimmick; it genuinely makes the medicine feel like a quick‑acting, refreshing sip rather than a gritty tablet. 3. How Quickly Does It Work? Onset: Within 5‑10 minutes after drinking the solution, I felt a noticeable easing of the “tight” feeling in my sinuses. The “pressure” around my forehead and cheeks dulled, and my throat irritation softened. Peak Relief: Around the 30‑minute mark, the combination of acetaminophen (pain/fever relief), chlorpheniramine (antihistamine), and phenylephrine (decongestant) hits its stride. Nasal passages feel clearer, the cough becomes less forceful, and the sneezing frequency drops dramatically. Verdict: The effervescent delivery system appears to speed up absorption compared with standard tablets or caplets, giving a perceptible relief in under 10 minutes.

Awesome!
It works!! Knocks that cold right out! Always consult physician before starting a new remedy. Excellent day-time med when you need to stay awake.

Mom’s Secret Weapon for Sick Days
When everyone in the house went down, this stuff worked fast. Made the worst symptoms manageable so I could keep being Mom‑in‑Charge. Knocked out the pain and soreness for me in about an hour and helped me sleep through the night. This steps up the original formula. Tastes great too. A must try for everyone.

Stellar product, always reliable when I’m sick
Great product for helping me and my family through this cold or flu virus going around. But I also want to comment on Amazon‘s customer service. My family and I are pretty sick and we just wanted to feel a little bit better and as delivery mistakes can happen which is completely normal, there was a delay and the customer service representative helped me get things back on track by ensuring swift shipment of a replacement. They were so very helpful and I’m so very thankful to have such great customer service representatives at Amazon. Also stellar medicine in helping me function throughout the day without too much ‘medicine-head’ or grogginess. Also recommend the night time version of this!

It works!
I have used this to help clear my sinuses when the occasional bug gets me. It is easy to use, easy to take with you, has a nice taste, but most important, it is effective! I feel like it provides good value. Recommended!

Plop, Plop, Fizz, Fizz
I've never had any issue with this product. It's always come through when I was sick and it's very effective. Seems to work much better than a pill. It doesn't taste too bad and very easy to use. I would recommend it.

Fast acting, very effective, and doesn't taste bad
I bought these by accident, but was desperate so I used them. I'm so glad I did! I have problems with cold medicine upsetting my stomach. This did not bother me at all. Additionally, I felt immediate relief. Within a minute. It doesn't taste bad at all. Not like an orange drink, but definitely not like medicine either. Maybe an orange club soda? I will definitely keep it on hand for future colds in my household. Just wish they made a nighttime version of the fizzy tablets. Highly recommend if you have a cold or the flu!
