  1. While Alka-Seltzer is typically safe to use, check in with your doctor before you decide to take it. Answer their questions about your medical history and let them know any concerns you have. If you want to give Alka-Seltzer to a child or teen, you should also check with your doctor first. You may not be able to take Alka-Seltzer for heartburn if: [1]
    • You are allergic to Alka-Seltzer or any of the ingredients (aspirin, citric acid, and sodium bicarbonate)
    • You have asthma, bleeding problems, or nose irritations or polyps
    • You are taking any other drug that includes aspirin
    • You are pregnant, plan to become pregnant, or are breastfeeding
  2. Always carefully read the instructions to prevent taking Alka-Seltzer too often. Adults and children over 12 can take 2 tablets every 6 hours. Just make sure not to exceed 7 tablets in 24 hours. If you're over 60, don't exceed 3 tablets in 24 hours. [2]
    • Your doctor might give you different dosage instructions. If that's the case, listen to your doctor.

  3. Pop the tablets out of the foil packet and drop them into a glass of water. The tablets will begin to fizz and dissolve immediately. [3]
    • Use room temperature water. Cold water will slow down the fizzing, and warm water will cause excessive fizzing. [4]
  4. Swallow the water as you normally would. You don’t have to drink it fast for it to be effective. Make sure to drink all of it so that you get the full dose of medicine. [5]
  5. If you frequently experience heartburn while you’re out and about, try carrying a packet of Alka-Seltzer ReliefChews with you. Simply pop them in your mouth, chew, and swallow when you feel symptoms coming on. The chews deliver fast relief, but they generally don’t work quite as quickly as the effervescent tablets. [6]
    • You can choose from a variety of flavors like Tropical Twist and Tropical Punch.

  1. While Alka-Seltzer Cold and Flu can’t cure you, it can offer temporary relief from your symptoms. Before you try it, talk to your doctor. They may advise you not to take it if: [7]
    • You are taking other drugs that include aspirin or take MAOIs (typically drugs for depression or other mental health issues)
    • You are under 12 years old
    • You have liver disease, heart disease, high blood pressure, diabetes, thyroid problems, or glaucoma
    • You have breathing problems, such as asthma or a persistent cough
  2. Alka-Seltzer Cold and Flu comes in many varieties. If your symptoms are keeping you from being productive during the day, choose a daytime, non-drowsy formula. If a cough or stuffy nose is keeping you up at night, take one of the nighttime formulas that can help you rest more easily. You can also purchase a package that contains both options.
    • The packages are very clearly marked, so just carefully read the label to make sure you’re purchasing what you want.
    • You can buy Alka-Seltzer at the pharmacy, a box store, or online.
  3. Pop 2 tablets into a glass of room temperature water and wait for them to fully dissolve. Once they are done fizzing, drink the glass of water as you normally would. Make sure to drink it all so that you get the full dose of medicine. [8]
  4. Alka-Seltzer is typically safe, but people do sometimes suffer from side-effects. Call your doctor immediately if: [9]
    • Your pain, cough, or congestion gets worse or lasts for more than 7 days
    • Your fever gets worse or lasts for more than 3 days
    • Redness, swelling, or a rash occurs
    • You are dizzy, nervous, or having trouble sleeping
