Is 500 or 1000mg needed for adults?

We begin by recalling that paracetamol has two main pharmacological activities, the antipyretic and the analgesic. This distinction is essential to describe the differences between the two dosages. In fact, for the antipyretic action 500mg every 4-6 hours orally and for the analgesic action 1000mg every 6 hours orally are sufficient.

For clarity, let's look at some examples:

-If I have a slight headache or fever I will take 500mg orally.

-If I have a severe toothache or severe post-op pain I will take 1000mg orally.

How many times a day?

As previously mentioned, paracetamol can be taken every 4-6 hours for the 500mg dose and every 6 hours for the 1000mg dose. It is important to follow this scheme without exceeding 3-4 grams per day orally for adults and 90mg/Kg orally for children.

Is paracetamol bad for you?

Like any drug, paracetamol can have side effects but in general it is a well-tolerated drug in the right dosages. If the recommended dosages are exceeded, liver damage may occur as the drug is hepatotoxic. It is advisable to take paracetamol and all medicines with caution and only when strictly necessary.

Is paracetamol useful for colds?

Acetaminophen 1000mg is often recommended for adults to cope with cold and other flu symptoms, even in the absence of a fever. In reality, most of the time this approach is not useful as the drug has no anti-inflammatory action. In these cases, other drugs such as ibuprofen or paracetamol in combination with other active ingredients will be more useful.

Practical example:

Do I have a stuffy nose, congested airways, cheekbone pain, earache, sore throat?

In these cases there is inflammation, edema with consequent blood dilatation. It will be more effective to take ibuprofen or paracetamol associated with decongestant active ingredients such as pseudoephedrine or phenylephrine.


Pay attention to the dosage of paracetamol (as with any drug) and do not exceed 3-4 grams per day for adults and 90mg/kg for children.

Always prefer, if possible, use orally rather than rectally.

Acetaminophen is useful for most pain and fever but has no anti-inflammatory action.
