Pregnancy Use

If you are pregnant or breastfeeding, it’s crucial to consult with a healthcare professional before using any medication.

As you age, it's important to be aware that the risk of severe stomach bleeding increases for individuals who are 60 years or older. This means that if you or a loved one falls into this age group, extra caution should be taken when using certain medications, especially those that can irritate the stomach.

Always consult with your healthcare provider about the safest options for you, and make sure to discuss any medications you are taking to help minimize potential risks. Your health and safety are paramount, and being informed can help you make better choices.

If you have liver problems, such as liver cirrhosis (a severe scarring of the liver), it's important to be aware of how this may affect your treatment. Your healthcare provider may need to adjust your medication dosage or closely monitor your liver function tests (tests that check how well your liver is working) to ensure your safety and the effectiveness of your treatment.

Additionally, if you have high blood pressure or heart disease along with liver issues, your doctor will consider these conditions when prescribing medications. Always communicate openly with your healthcare team about your liver health to receive the best care tailored to your needs.
