Before starting EQUALINE®, it's advisable to consult with your doctor or healthcare provider, especially if you have specific health concerns related to your heart.

Always err on the side of caution—if you notice anything concerning, don’t hesitate to reach out for assistance. Quick action can make a significant difference in ensuring your safety and well-being.

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. Using aspirin at this stage can lead to potential issues for your unborn child or complications during delivery. Always prioritize your health and the health of your baby by seeking professional advice.

As you age, it's important to be aware of certain health risks when taking medications. If you are 60 years or older, there is a higher chance of experiencing severe stomach bleeding. This risk is especially relevant if you have a history of stomach issues, such as heartburn, or if you have conditions like high blood pressure, heart disease, liver cirrhosis (a liver condition), or kidney disease.

Before starting any new medication, it's wise to consult with your doctor to ensure it's safe for you, particularly if any of these warnings apply to your health situation. Taking this precaution can help you manage your health more effectively and avoid potential complications.
