How Ceftriaxone injection is given
Ceftriaxone Injection is usually given by a doctor or nurse. It can be given as a drip (intravenous infusion) or as an injection directly into a vein or into a muscle. Ceftriaxone Injection is made up by the doctor, pharmacist or nurse and will not be mixed with or given to you at the same time as calcium-containing injections.
The usual dose
Your doctor will decide the correct dose of Ceftriaxone Injection for you. The dose will depend on the severity and type of infection; whether you are on any other antibiotics; your weight and age; how well your kidneys and liver are working. The number of days or weeks that you are given Ceftriaxone Injection depends on what sort of infection you have.
Adults, older people and children aged 12 years and over with a body weight greater than or equal to 50 kilograms (kg):
- 1 to 2 g once a day depending on the severity and type of infection. If you have a severe infection, your doctor will give you a higher dose (up to 4 g once a day). If your daily dose is higher than 2 g, you may receive it as a single dose once a day or as two separate doses
Newborn babies, infants and children aged 15 days to 12 years with a body weight of less than 50 kg:
- 50-80 mg Ceftriaxone Injection for each kg of the child’s body weight once a day depending on the severity and type of infection. If you have a severe infection, your doctor will give you a higher dose up to 100 mg for each kg of body weight to a maximum of 4 g once a day. If your daily dose is higher than 2 g, you may receive it as a single dose once a day or as two separate doses
- Children with a body weight of 50 kg or more should be given the usual adult dose
Newborn babies (0-14 days)
- 20 – 50 mg ceftriaxone for each kg of the child’s body weight once a day depending on the severity and type of infection

People with liver and kidney problems
You may be given a different dose to the usual dose. Your doctor will decide how much Ceftriaxone Injection you will need and will check you closely depending on the severity of the liver and kidney disease.
If you are given more Ceftriaxone Injection than you should
If you accidentally receive more than your prescribed dose, contact your doctor or nearest hospital straight away.
