What is calculadora.dalsy?

calculadora.dalsy is a practical dose-estimation tool for caregivers who need a quick and clear way to convert an ibuprofen dose from mg/kg into mL. In many countries, Dalsy is a well-known pediatric ibuprofen syrup, but the exact concentration can vary by product. That concentration difference is exactly why so many dosing mistakes happen at home.

This page gives you a safer framework: calculate by weight, check concentration, and verify the total amount over 24 hours. Even when a child has had ibuprofen before, dose checks are worth doing each time.

How the calculator works

1) Dose per administration

The core formula is straightforward:

• mg per dose = weight (kg) × chosen mg/kg

Example: 18 kg child at 7.5 mg/kg → 135 mg per dose.

2) Convert mg to mL

Liquid medicines are administered in milliliters, so we convert using concentration:

• mL per dose = mg per dose ÷ concentration (mg/mL)

For 20 mg/mL, 135 mg equals 6.75 mL.

3) Daily safety check

Spacing doses every 6 to 8 hours changes the total amount in a day. The calculator compares your planned daily intake with a selected daily cap (default: 30 mg/kg/day):

• max daily mg = weight (kg) × max daily mg/kg
• planned daily mg = mg per dose × doses/day

If the planned daily value exceeds your selected limit, the result will show a warning.

Why concentration matters so much

Two bottles may look similar but have different strengths. Giving the same volume from a 40 mg/mL product as you would from a 20 mg/mL product can unintentionally double the dose. Before each administration:

• Read the label concentration carefully (mg/mL).
• Use an oral syringe, not a kitchen spoon.
• Re-check the child's current weight if possible.

Step-by-step use at home

1. Enter the child's weight in kilograms.
2. Select the exact concentration printed on the bottle.
3. Choose a dose target (often 5 to 10 mg/kg, depending on guidance).
4. Choose the interval (6h or 8h) and review the daily total.
5. Confirm with your healthcare professional whenever uncertain.

Safety checklist

• Do not combine multiple ibuprofen products.
• Avoid dosing more frequently than advised.
• Keep hydration in mind during fever, vomiting, or diarrhea.
• Seek urgent care for breathing difficulty, persistent lethargy, severe pain, or signs of allergic reaction.
• If fever persists beyond expected duration, contact a clinician rather than repeatedly escalating doses.

Frequently asked questions

Can I use age instead of weight?

Weight-based dosing is generally safer and more precise. Age bands can be rough estimates only.

Is higher mg/kg always better for fever?

Not necessarily. The goal is symptom relief with safe spacing and safe total daily limits. More is not always better.

Can this replace professional advice?

No. This calculator is a support tool for arithmetic and planning. Final clinical decisions should come from qualified medical professionals familiar with your child's situation.

Final note

Use this tool as a double-check, not as a diagnosis engine. When in doubt, pause and call your pediatrician or local health service. A quick verification can prevent avoidable medication errors.
