Drug Overview

H-E-B Ultra Strength Antacid Tablets are chewable tablets designed to provide relief from common digestive discomforts. Each tablet contains 1000 mg of calcium carbonate, which works as an antacid to help alleviate symptoms such as heartburn, acid indigestion, sour stomach, and upset stomach associated with these issues. Available in assorted berry flavors, these gluten-free tablets offer a convenient option for managing occasional digestive upset.

This product is comparable to Ultra Strength Tums, although it is not manufactured or distributed by GlaxoSmithKline LLC, the owner of the Tums trademark. With a commitment to quality, H-E-B ensures that these tablets are made with care and pride in San Antonio, TX.

Uses

If you're experiencing discomfort from heartburn, acid indigestion, or a sour stomach, this medication can help relieve those symptoms. It is also effective for soothing an upset stomach that may be associated with these issues.

You can feel confident using this medication, as there are no known teratogenic effects (which means it doesn't cause birth defects) or other harmful effects noted.

Dosage and Administration

When you need relief from certain symptoms, adults and children aged 12 and older can chew 2 to 3 tablets as needed. It's important to chew the tablets completely instead of swallowing them whole. This helps ensure that the medication works effectively.

However, if your symptoms last longer than 2 weeks, you should consult a doctor before continuing to take the medication. It's always best to seek professional advice if you're unsure about your symptoms or how to manage them.

What to Avoid

It's important to use this medication safely to avoid potential risks. You should not use it if the printed seal under the cap is torn or missing, as this could indicate that the product is compromised. Additionally, be mindful of the dosage: do not take more than 7 tablets in a 24-hour period, and if you are pregnant, limit your intake to no more than 5 tablets in that same timeframe.

For your safety, avoid using the maximum dosage for more than 2 weeks unless your doctor has advised and is supervising you. Following these guidelines can help prevent misuse and dependence (a condition where your body becomes reliant on a substance). Always prioritize your health and consult with a healthcare professional if you have any questions or concerns.

Side Effects

It's important to be aware that antacids can interact with some prescription medications, which may affect how well those medications work. If you are taking any other medications, be sure to discuss this with your healthcare provider to avoid any potential issues.

While specific side effects were not detailed, always monitor how you feel after taking any medication and report any unusual symptoms to your doctor. Your health and safety are paramount, so staying informed is key.

Warnings and Precautions

It's important to use this medication safely. You should not take more than 7 tablets in a 24-hour period. If you are pregnant, limit your intake to no more than 5 tablets in 24 hours. Additionally, avoid using the maximum dosage for more than 2 weeks unless your doctor has advised you to do so.

While there are no specific emergency instructions or lab tests mentioned, always be mindful of how your body responds to the medication. If you experience any unusual symptoms or have concerns, it's best to consult your doctor for guidance.

In case of an emergency, call your local emergency number or go to the nearest hospital. Always keep medications out of reach of children and follow the prescribed dosage to prevent any potential risks. If you have any concerns or questions about your medication, don’t hesitate to reach out to your healthcare provider for guidance.

Pregnancy Use

If you are pregnant, it is important to be cautious with your medication. You should not take more than 5 tablets in a 24-hour period.

When it comes to using this medication in older adults, there is no specific information available about dosage adjustments, safety concerns, or special precautions. This means that healthcare providers may not have tailored guidelines for elderly patients.

If you or a loved one is an older adult considering this medication, it’s important to discuss any potential risks and benefits with your healthcare provider. They can help determine the best approach based on individual health needs and circumstances.

Renal Impairment

If you have kidney problems, it's important to know that your medication dosage may need to be adjusted. Specifically, if you have reduced creatinine clearance (a measure of how well your kidneys are filtering waste), you should be closely monitored by your healthcare provider. Regular renal function tests are essential both before starting treatment and during it to ensure your kidneys are handling the medication properly.

For those with moderate to severe renal impairment, a lower dose of the medication is recommended. Additionally, if you have end-stage renal disease, special considerations will be necessary to ensure your safety and the effectiveness of your treatment. Always discuss your kidney health with your doctor to receive the best care tailored to your needs.

Hepatic Impairment

If you have liver problems, it's important to know that your dosage of this medication may need to be adjusted. This is because your liver's ability to process the drug can be affected. Additionally, your healthcare provider will likely recommend special monitoring of your liver function tests (which check how well your liver is working) to ensure your safety while taking this medication.

Caution is advised when using this drug if you have liver impairment, as it may change how your body metabolizes (processes) the medication. Always discuss your liver health with your doctor to ensure you receive the appropriate care and adjustments needed for your treatment.

Drug Interactions

It's important to have open conversations with your healthcare provider about any medications or tests you may be taking. While there are no specific drug interactions or laboratory test interactions noted for this medication, your healthcare provider can help ensure that everything you are taking works well together and is safe for you. Always share your complete list of medications and any health conditions you have to receive the best care possible.
