Hypothyroidism during the Covid Pandemic

During the Coronavirus pandemic your GP may decide that you can undergo monitoring blood tests less often.  We normally check patient’s bloods once a year once they are stable on treatment, but if your dose as been stable for some time we may extend the interval between blood tests to longer than one year.

If you are concerned that you may need a blood test to assess if your dose needs adjusting, please contact the surgery for a telephone consultation with your GP.

Symptoms of an underactive thyroid can include:

  • Tiredness
  • weight gain
  • depression
  • being sensitive to the cold
  • dry skin and hair
  • muscle aches
  • constipation

Advice around taking thyroid medications:

Taking your thyroxine tablets correctly will mean that are more effective.

  • Take your tablets at the same time every day
  • They should be taken on an empty stomach, we recommend first thing in the morning
  • Avoid eating for 30 minutes afterwards
  • Certain other medications can affect the absorption of thyroxine medication, these should be taken several hours apart.  They include: calcium tablets and medicines to reduce stomach acid such as proton-pump inhibitors.  If you are uncertain about drug interactions, please make a telephone appointment with our Clinical Pharmacist Helen Murray.


If you are prescribed thyroxine you are entitled to a medical exemption certificate.  This means you don’t have to pay for prescriptions.
