It can help alleviate symptoms such as acid indigestion, sour stomach, heartburn, and upset stomach associated with these issues.

This antacid is calcium-rich and comes in a convenient package of 100 tablets, making it easy to take whenever you need relief. If you're experiencing any of the symptoms mentioned, Medi-First Plus Antacid may be a helpful option for you.

Uses

If you're experiencing discomfort from acid indigestion, sour stomach, or heartburn, this medication can help relieve those symptoms. It is also effective for easing an upset stomach that comes along 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) associated with it.

Dosage and Administration

If you are an adult or a child aged 12 years and older, you can take this medication by chewing 2 tablets every 2 to 3 hours as needed for your symptoms. If your symptoms persist, you can repeat the dose every hour, but be careful not to exceed 19 tablets in a 24-hour period.

For children under 12 years old, it's important to consult a doctor before giving them this medication. Always follow your healthcare provider's advice to ensure safe and effective use.

It's important to use this product safely to avoid potential risks. You should not use the maximum dosage for more than two weeks unless your doctor advises you to do so. Additionally, make sure not to take more than 19 tablets in a 24-hour period. If your symptoms last longer than two weeks, please stop using the product and consult your doctor for further guidance.

Side Effects

It's important to be aware that antacids can interact with some prescription medications, which may affect how well those medications work.

Always consult with your healthcare provider if you have any concerns about using antacids or if you experience any unusual symptoms.

Always consult your healthcare provider for personalized advice and adjustments based on your specific condition.

Make sure to keep your doctor informed about your liver health, as they may want to conduct regular liver function tests (which check how well your liver is working) to ensure your safety while using any medication.

Drug Interactions

It's important to be aware that antacids can interact with some prescription medications.
