1. What Klaricid IV is and what it is used for

Klaricid IV contains the active ingredient clarithromycin. Klaricid belongs to a group of medicines called macrolide antibiotics. Antibiotics stop the growth of bacteria (bugs) that cause infections.

Klaricid IV is used whenever an intravenous (injection into the vein) antibiotic is required to treat severe infections or, alternatively, if a patient cannot swallow Klaricid tablets.

It is used to treat infections such as:

1. Chest infections such as bronchitis and pneumonia
2. Throat and sinus infections
3. Skin and tissue infections

Klaricid IV is indicated in adults and children 12 years and older.

2. What you need to know before receiving Klaricid IV

  • are taking medicines called terfenadine or astemizole (widely taken for hay fever or allergies) or cisapride or domperidone (for stomach disorders) or pimozide (for mental health problems) as combining these drugs can sometimes cause serious disturbances in heart rhythm. Consult your doctor for advice on alternative medicines.
  • are taking other medicines which are known to cause serious disturbances in heart rhythm.
  • are taking lovastatin or simvastatin (HMG-CoA reductase inhibitors, commonly known as statins, used to lower levels of cholesterol (a type of fat) in the blood).

  • are taking colchicine (usually taken for gout)

Driving and Using Machines:

Klaricid IV may make you feel dizzy or drowsy. If they affect you in this way do not drive, operate machinery or do anything that requires you to be alert.

3. How is Klaricid IV given?

Klaricid IV is prepared by your doctor or nurse by dissolving the powder in the vial in sterile water. The solution obtained is added to a larger volume of sterile liquid. Klaricid IV is given to you slowly through a needle, into your vein over a period of at least an hour.

The recommended dose of Klaricid IV for adults and children over 12 years is 1.0g per day, split into two doses, for 2 to 5 days. Your doctor will work out the correct dose for you.

Children under 12 years should not be given Klaricid IV. Your doctor will prescribe another suitable medicine for your child.

If a child accidentally swallows some of this medicine, seek medical advice urgently.

If you are given more Klaricid IV than you should have

As Klaricid IV is given to you by a doctor, an overdose is unlikely but symptoms may include vomiting and stomach pains.
