I think several things are happening here. First look at my post on Learning to Use My Medicine
Fludrocortisone (or Fludrocort or Floroinef- brand name) is NOT a salt pill. It is a synthetic adrenal hormone. It is used to replace one of the major adrenal hormones, aldosterone. Most people with Addison's Disease need to take Fludrocort (1 pill .1mg) daily. Aldosterone controls mineral balances in our bodies, mainly the salt and potassium balance. Aldosterone therefore regulates your blood pressure and water retention levels in your body. It also regulates nerve impulses. Most people have to take potassium pills when they take Fludrocort since Fludrocort causes the body to retain salt and dump potassium.
Symptoms of Too Little Aldosterone or Fludrocort
- low blood pressure (110/70 or less)
- extreme fatigue
- pain with movement
- dizzy and lightheaded
- crave salt (low salt)
- high potassium
- drink excessive amounts of water
- excessive urination (15 to 20 times a day)
- low hydration (sign of dehydration - rough tongue, dry skin)
- excessive perspiration
- weak leg muscles
- difficult to move
- muscle twitches
- heart palpitations (pounding or racing)
- symptoms worse after drinking coffee or alcohol (increases dehydration)
Symptoms of Too Much Fludrocort
- high blood pressure (140/90 or more)
- puffy feet and hands (swelling from water retention)
- low potassium
- high salt
- sudden weight gain
- short of breath
- uneven heart rate
- muscle pain or weakness
- increased thirst or urination
Yes, some of the symptoms are the same. That is because any mineral imbalance causes problems. For instance you can have too much salt or too much potassium in your blood and the body tries to re-balance by causing you to drink more water or eliminate water.
You do not need to guess if you are too high or low in fludrocort. Just check your blood pressure with a monitor (available at most drug stores). If your blood pressure is high your fludrocort is too high. If your blood pressure is too low your fludrocort is too low. Fludrocort levels are directly related to blood pressure.
There are also blood tests that will directly measure the level of fludrocort in your blood.
Most people who have Addison's disease must take fludrocort because our bodies do not produce aldosterone which regulates mineral balance. Therefore most people take .1 mg (one pill) each morning. This dose usually stays constant.
