It's important to note that there are no reported teratogenic effects (which means it does not cause birth defects) associated with this medication.

Dosage and Administration

If you are an adult or a child aged 12 years and older, you should take 2 caplets every 6 hours as long as you have symptoms. However, make sure not to exceed 6 caplets in a 24-hour period unless your doctor advises otherwise.

If you experience any of these symptoms, stop using the medication and seek medical help immediately.

Drug Interactions

It's important to be aware that taking acetaminophen (a common pain reliever) alongside warfarin (a blood thinner) can increase the effects of warfarin. This combination may raise your risk of bleeding, so if you are using both medications, your healthcare provider will likely want to monitor your INR (a blood test that measures how long it takes your blood to clot) closely.

Always discuss any medications you are taking with your healthcare provider, including over-the-counter drugs like acetaminophen. They can help ensure that your treatment is safe and effective, especially if you are on medications that can interact with each other.
