It's important to follow specific guidelines when using this medication to ensure your safety. You should not use the product if the printed seal under the cap is torn or missing. Additionally, avoid taking more than 7 tablets within a 24-hour period. If you are pregnant, limit your intake to no more than 5 tablets in 24 hours. Lastly, do not use the maximum dosage for more than 2 weeks unless directed and supervised by your doctor.

By adhering to these instructions, you can help prevent potential risks associated with misuse or overuse of the medication. Always consult with your healthcare provider if you have any questions or concerns about your treatment.

Side Effects

It's important to be aware of potential side effects when using this medication. Some individuals may experience adverse reactions, which can vary in severity. If you are currently taking any prescription medications, it's crucial to consult with your doctor or pharmacist before starting this treatment, as antacids can interact with certain drugs.

Always keep an eye out for any unusual symptoms and report them to your healthcare provider. Your safety and well-being are the top priority, so don't hesitate to seek guidance if you have any concerns.
