Infections/ vaccinations


I have an infection and I am taking antibiotics – should I stop taking my other medications?

Ordinarily you would not need to stop your disease-modifying treatment whilst taking antibiotics. If you are taking; Methotrexate, Sulfasalazine, Leflunomide, Mycophenolate or Azathioprine, however, we advise you to omit this if you develop an infection, since its immunosuppressive effects may hinder your recovery.

You should not take biologic medication if you are unwell due to an infection or on antibiotics; notify the Rheumatology team if your illness persists for more than a week.

I have been in contact with somebody with shingles, what should I do?

If you are on a drug that suppresses your immune system (i.e. reduces your body’s defence mechanism against infections) and if you come in close contact with anyone who has chicken pox or shingles you should contact your GP for advice as treatment may be required.

Drugs that can alter your response to infection include:

  • methotrexate
  • leflunomide
  • ciclosporin
  • azathioprine
  • mycophenolate
  • biologics drugs


Close contact means:

  • being in the same room as someone who has shingles for more than 15 minutes or
  • having immediate contact with someone who has shingles on many parts of their body or where it is exposed, e.g. on the face

Where possible you should keep away from anyone you know who has chicken pox or shingles. There are guidelines regarding receiving the vaccine according to age. If you have been offered the shingles vaccine and are on one of the drugs listed above, please contact us to discuss before receiving the vaccine.

What should I do if I get chicken pox whilst on Methotrexate?

Notify your own GP as soon as possible as you may need treatment to minimise the severity of the disease.



Can I have vaccinations whilst I am on medication for my condition?

If your immune system is suppressed due to medication, it is particularly important that you are adequately protected. If you are receiving treatment with immunosuppressive drugs such as methotrexate, leflunomide, azathioprine, biologic drugs you should avoid ‘live’ vaccinations: these include oral polio vaccine, yellow fever vaccine and German measles (Rubella). An alternative inactivated polio vaccine is available, if required.

You should also avoid contact, where possible, with adults or children who have received the ‘live’ oral polio vaccine, for six weeks after vaccination: in particular you should not change babies’ nappies, since they will excrete the live polio virus in their faeces for this time.

Vaccination against yellow fever may be an entry requirement for some countries, so discuss this with your GP before making travel arrangements. If you are planning to travel abroad, you should seek advice from your GP at least six weeks before your departure since some vaccinations may need ordering for you.

Should I have the flu and/or pneumonia vaccinations?

If you are on immunosuppressive medication such as Methotrexate and anti-TNF (Biological treatment) the flu vaccination (which is inactivated) is recommended on a yearly basis. Likewise, the pneumonia (pneumococcal) vaccine is recommended for all patients with rheumatological conditions on immunosuppressive drugs.
