Pregnancy Use

If you are pregnant or breastfeeding, it’s crucial to consult with a healthcare professional before using any medication. This is particularly important for aspirin; you should avoid taking it after 20 weeks of pregnancy unless your doctor specifically instructs you to do so.

Geriatric Use

As you age, it's important to be aware of certain health risks associated with medications. If you are 60 years or older, there is a higher chance of experiencing severe stomach bleeding. This risk means that you should be particularly cautious and discuss any medications you are taking with your healthcare provider, especially if they are known to affect the stomach.

Always make sure to inform your doctor about your age and any other health conditions you may have, as they can help you manage your medications safely and effectively. Your health and safety are the top priority, so don't hesitate to ask questions or express any concerns you may have.
