Always prioritize your child's safety and consult a healthcare professional if you have any concerns.

Geriatric Use

Always consult with your healthcare provider about the safest options for you, and make sure to discuss any medications you are taking. They can help you understand the risks and adjust dosages if necessary to ensure your safety and well-being.

They should also be advised to seek medical advice if their pain worsens or lasts longer than 10 days, if redness or swelling occurs, if fever worsens or lasts more than 3 days, if new symptoms develop, or if they experience ringing in the ears or loss of hearing, as these may indicate a serious condition.

Healthcare providers should encourage patients to consult a doctor before use if they have a history of stomach problems, such as heartburn, or if the stomach bleeding warning applies to them. Patients with high blood pressure, heart disease, liver cirrhosis, or kidney disease should also seek medical advice prior to use.
