Cef-3 is available as a powder for suspension in a 30ml bottle.  

Composition: Each 5 ml of the reconstituted suspension typically contains Cefixime Trihydrate USP equivalent to Cefixime 100 mg. This means a 30ml bottle would contain a total of 600mg of Cefixime.

Indications: Cef-3 (Cefixime) is a third-generation cephalosporin antibiotic used to treat various bacterial infections such as:

• Upper and lower respiratory tract infections  
• Urinary tract infections  
• Acute otitis media  
• Pharyngitis and tonsillitis  
• Uncomplicated gonorrhea

Dosage and Administration for Children:The usual dose for children is 8 mg/kg/day, given as a single dose or in two divided doses for 7-14 days, depending on the severity of the infection.  

Based on a Cef-3 suspension strength of 100mg/5ml, here are general dosage guidelines:

• 6 months up to 1 year:3.75 ml daily (75 mg).  
• 1-4 years:5 ml daily (100 mg).  
• 5-10 years:10 ml daily (200 mg).  
• 11-12 years: 15 ml daily (300 mg).

For a 30ml bottle of Cef-3 suspension (100mg/5ml), the total amount of Cefixime is 600mg. The duration this bottle will last depends on the prescribed daily dose.

For your specific situation, always follow the dosage prescribed by your child's doctor, as it depends on their weight and the severity of the infection.

Directions for Reconstitution: To prepare a 30 ml suspension, usually, you will need to add a specific amount of boiled and cooled water to the powder in the bottle. This amount is typically mentioned in the product leaflet. For a 30ml bottle of Cef-3 (100mg/5ml), it is often around 20 mlof water added in two portions, shaking well after each addition until the powder is completely mixed.
