Side Effects

Taking this product can lead to serious side effects, particularly related to your liver.

Warnings and Precautions

This product contains acetaminophen, which can cause severe liver damage if you exceed 8 tablets (4000mg) in 24 hours, take it with other medications that also contain acetaminophen, or consume 3 or more alcoholic drinks daily while using it. If you have liver disease or are taking the blood-thinning medication warfarin, consult your doctor before using this product.

If you suspect an overdose, seek emergency medical help or contact a Poison Control Center immediately, even if you don’t notice any symptoms. It’s important to act quickly for both adults and children. Additionally, stop using this product and call your doctor if your pain worsens or lasts more than 10 days, your fever worsens or lasts more than 3 days, you develop new symptoms, or if you notice any redness or swelling, as these could indicate a serious issue.

Overdose

If you suspect an overdose, it’s important to seek medical help immediately or contact a Poison Control Center. This is crucial for both adults and children, even if you don’t see any signs or symptoms of an overdose.

This means that there are no tailored guidelines for how this medication should be used if you have renal impairment (kidney issues).

Always consult your healthcare provider for personalized advice and to ensure that any medication you take is safe and appropriate for your health situation. They can help determine the best course of action based on your kidney function and overall health.
