Dalsy: what is it, what is it for and dose according to your child’s age

Dalsy is one of the most popular children’s medications, standing out for being an anti-inflammatory, analgesic and antipyretic. Do you want to know when it is appropriate to give it? Find out everything you need to know.

Although Apiretal is considered one of the best-known, most popular and used by many mothers and fathers for the treatment of mild or moderate pain and fever in children, it is true that there is also another drug of recognized popularity: Dalsy.

Since its active principle is ibuprofen (as is also the case with Apiretal), it is a drug that is also used not only to relieve pain but also to lower high fever in children.

What is Dalsy?

Dalsy is a children’s medicine that acts as an anti-inflammatory, an anti-term, and a pain reliever. That is, it is a non-steroidal anti-inflammatory capable of reducing inflammation, reducing high fever, and also calming pain.

It is presented in the form of a syrup (that is, an oral suspension), and it is a drug whose ibuprofen composition is obviously adapted so that children can take it safely, as it has a lower dose and also in form or presentation liquid.

However, as with the correct dose of Apiretal, in the case of Dalsy it is also very important to adapt the dose of Dalsy to the child’s weight.

When is it appropriate to give Dalsy?

Since Dalsy is a non-steroidal anti-inflammatory that also acts as an antiterm and analgesic, it is especially indicated for:

  • Decrease high fever.
  • Reduce inflammation.
  • Soothe mild or moderate pain.

Therefore, it is a suitable medicine for children older than 3 months or weighing more than 5 kg. Of course, if your child is less than 2 years old, it is always very important to consult the pediatrician, since he will be the most suitable specialist to prescribe it to the child as safely as possible.

Dalsy contraindications: when is it not appropriate to take it?

Although we are facing a safe children’s medicine, we must bear in mind that not all children can take it. For example, it is not suitable for children under 3 months, or weighing less than 5 kg.

In addition, its consumption is not recommended in the following cases:

  • When you have chickenpox.
  • Before vomiting or severe diarrhea.
  • Severe liver, kidney, or heart disease.
  • Faced with stomach problems.
  • Allergy to ibuprofen or other non-steroidal anti-inflammatory drugs.

How to keep Dalsy correctly once opened?

It is advisable first of all to write down the date of opening of the medicine on the Dalsy container box, and always keep it inside the box together with its leaflet (to have it handy when we need to consult it again).

It is not necessary to keep Dalsy in the refrigerator, but it is very important to keep it in a cool place below 25ºC. Also, you should keep in mind that this drug expires after 12 months once opened.
