Dalsy Calculator

Dalsy dosage is calculated based on the child's weight, applying the formula of 20-30 mg of ibuprofen per kilogram of body weight per day. This total amount is divided into 3 doses, administered every 8 hours. For example, for a 15 kg child, the recommended dose per administration would be approximately 5-7.5 ml of Dalsy 40 mg/ml or 10-15 ml of Dalsy 20 mg/ml.

The difference between Dalsy 20 mg/ml and Dalsy 40 mg/ml is the ibuprofen concentration. Dalsy 20 mg/ml contains 20 milligrams of ibuprofen per milliliter, while Dalsy 40 mg/ml contains 40 milligrams per milliliter. Therefore, with Dalsy 40 you will need to administer half the volume (ml) than with Dalsy 20 to achieve the same ibuprofen dose.

Dalsy can be administered every 8 hours, that is, 3 times a day. It is important to respect this time interval and not exceed the recommended maximum daily dose. If fever or pain persists after 3 days of treatment, you should consult with the pediatrician.

The maximum Dalsy dose depends on the child's weight. The maximum dose per administration is 400 mg of ibuprofen, and the maximum daily dose is 30 mg/kg/day (up to a maximum of 1200 mg per day for children over 12 years or weighing more than 40 kg). This amount should never be exceeded without medical indication.

For children under 2 years, Dalsy requires a medical prescription. This medication should not be administered to infants or very young children without a pediatrician's indication and supervision, as the dose must be carefully adjusted according to the baby's weight and age.

If you have administered more Dalsy than the recommended dose, contact your pediatrician or emergency services immediately. Ibuprofen in excessive doses can cause side effects such as stomach pain, nausea, vomiting, or kidney problems. It is important to bring the medication package so the doctor knows the amount administered.

Yes, Dalsy (ibuprofen) and paracetamol can be alternated under medical supervision. Many pediatricians recommend this alternation to better control high fever, administering one every 4 hours (with an 8-hour interval for each medication individually). However, you should always consult your doctor before combining medications.

Dalsy usually takes effect in 30-60 minutes after administration. The antipyretic effect (lowers fever) and analgesic (relieves pain) can last between 6 and 8 hours. If you don't see improvement after 1 hour, don't increase the dose without consulting your pediatrician first.
