Fusidic Acid (Injection, Oral)

Fusidic Acid is a treatment taken orally or by injection and used against staphylococcal (bacterial) infections.

Overview

Fusidic Acid is used to treat staphylococcal infections occurring because of bacteria. Commonly treated ailments include cutaneous infections, pneumonia, septicaemia, wound infections, endocarditis, osteomyelitis and superinfected cystic fibrosis.

This medication is usually given orally unless oral administration is inappropriate. This could occur because of stomach discomfort or because absorption from the gastro-intestinal tract is unpredictable.

Fusidic Acid will not be effective in the treatment of viral infections such as the flu or colds.

This medication is only available when prescribed by a doctor and is administered as Fucidin Suspension in a range of forms.

In addition to the much needed effects of this medication, Fusidic Acid can also cause unwanted side effects to occur. While not all of these side effects may occur, patients may need to seek medical attention in cases where they do.

Interactions

Certain medications should not be used in conjunction with one another. This is because they can interact with each other in the body and this can cause severe medical problems in the patient. When medications react violently there can be life-threatening results. In other cases medications may prevent one another from working or may increase the risk of certain side effects occurring from one or both of the treatments. Before beginning treatment with any medication it is very important that you inform your doctor of any other treatments that you are taking so that you can avoid experiencing any unwanted interactions. This includes any herbal remedies, vitamin supplements, dietary supplements, over the counter treatments and prescribed medications that you are taking. For Fusidic Acid this is especially important in the following cases.

The use of Fusidic acid is not normally recommended in patients who are taking any of the following. When treatment with both medications is required the doses or frequency of use of each medication must be amended as appropriate to the situation:

  • Simvastatin
  • Saquinavir
  • Ritonavir
  • Pravastatin
  • Cholera Vaccine, Live
  • Atorvastatin

Other drug interactions can also occur that have not been listed here. Ensure that you have informed your doctor of all medications that you are taking before taking Fusidic Acid.

Certain medical conditions can also impact the use of certain treatments. Conditions not being treated with a medication may be worsened by use or may increase the side effects that are experienced from use of the medication. You should inform your doctor of your full medical history before beginning treatment. In the case of fusidic acid, the following condition may be significantly worsened by the use:

Warnings

Before you begin use of any medication you must weigh the benefits of use against the potential risks of use. The decision to take any treatment should be made with your doctor and should take into account all of the following:

Allergies: If you have any allergies this may effect the use of Fusidic acid. Ensure your doctor is aware of all allergies to dyes, preservatives, medications, foods, animals or other substances before beginning treatment.

Breastfeeding: There have been no adequate studies carried out to determine the risk of breastfeeding during use of this treatment. You should weigh the potential risks of breastfeeding with the benefits and discuss this with your doctor.

You should check in with your doctor if you are not experiencing an improvement in your condition after a few days of treatment. This may mean that there is another condition that may need to be treated too.

You should not take any other medications at the same time or during the same period as taking Fusidic Acid unless expressly told to by your doctor. If you need other treatment for pain relief or other conditions then you should discuss the use of these with your doctor. You should not take any medications purchased over the counter intended for the treatment of coughs, colds, hay fever, sinus problems, aspirin or medications for sinus problems. All of these may interact with fusidic acid and may make conditions worse rather than better.
