How long does Alka-Seltzer take to show effect?

Hi, I have had laryngitis for 3 days. I have been taking alka seltzer cold and cough around the clock. I also have some chest congestion and have coughed up some green/yellow stuff. I have also been gargling warm salt water on the hour for 3 DAYS. My question is how much longer should I wait before I seek additional help? I don t really feel bad, I have been very sleepy and I cannot talk at all.

Hello,

After the Alka-Seltzer tablet was added to the hot water the tablet should have quickly dissolved, taking some 20 to 30 seconds to do so, depending on the exact temperature.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Esmeralda Sera, Oncologist

I swell everyday, and take lasix to get the water off, lately my stomach has been upset and I ve taken a few plain Alka Seltzers and it seem the swelling is worse. Is this a side effect and does the sodium in the Alka Seltzer make it worse? Thanks, Tom Barnes

I have problems with my bowels. It is very noisy, making all sorts of sounds. My stools vary from liquid like water to solid. The only thing which seems to hep is Antacid, Alka Seltzer. I try to take a minimum. Do you think that an extended use of that medicine is dangerous? What are the side effects?

I understand that Minocycline needs to be taken away from magnesium by 2 hours. My daughter just took an alka seltzer gold, not realizing it contains magnesium as an inactive ingredient. Because it is an inactive ingredient, it does not tell us how much magnesium the tablets contain. Can she take her minocycline, which is now due, or should she wait two hours? Thanks!
