Patients who have a rise in creatinine on three or more occasions, even if their eGFR is > 60 ml/min/
1.73m2 require further evaluation, including a urinalysis for haematuria, proteinuria, a review of their medical history with attention paid to cardiovascular, urological and medication history, and blood pressure control and management. Overt proteinuria should be further quantified with a urine protein to creatinine ratio. Discontinuation
For patients who have achieved long term remission, it is recommended to discontinue lithium gradually and in a controlled fashion. Cluster headaches, migraine and hypnic headache
Studies testing prophylactic use of lithium in cluster headaches (when compared to verapamil), migraine attacks and hypnic headache indicate good efficacy. Adverse effects
Sources for the following lists. Very Common (> 10% incidence) adverse effects of lithium include
Confusion
Constipation (usually transient, but can persist in some)
Decreased memory
Diarrhea (usually transient, but can persist in some)
Dry mouth
EKG changes — usually benign changes in T waves
Hand tremor (usually transient, but can persist in some) with an incidence of 27%. If severe, psychiatrist may lower lithium dosage, change lithium salt type or modify lithium preparation from long to short acting (despite lacking evidence for these procedures) or use pharmacological help
Headache
Hyperreflexia — overresponsive reflexes
Leukocytosis — elevated white blood cell count
Muscle weakness (usually transient, but can persist in some)
Myoclonus — muscle twitching
Nausea (usually transient)
Polydipsia — increased thirst
Polyuria — increased urination
Renal (kidney) toxicity which may lead to chronic kidney failure
Vomiting (usually transient, but can persist in some)
Vertigo
Weight gainCommon (1–10%) adverse effects include
Acne
Extrapyramidal side effects — movement-related problems such as muscle rigidity, parkinsonism, dystonia, etc.
Fludrocortisone, sold under the brand name Florinef, among others, is a corticosteroid used to treat adrenogenital syndrome, postural hypotension, and adrenal insufficiency. In adrenal insufficiency, it is generally taken together with hydrocortisone. Fludrocortisone is taken by mouth and is most commonly used in its acetate form.Common side effects of fludrocortisone include high blood pressure, swelling, heart failure, and low blood potassium. Other serious side effects can include low immune-system function, cataracts, muscle weakness, and mood changes. Whether use of fludrocortisone during pregnancy is safe for the fetus is unknown. Fludrocortisone is mostly a mineralocorticoid, but it also has glucocorticoid effects.Fludrocortisone was patented in 1953. It is on the World Health Organizations List of Essential Medicines. Medical uses
Fludrocortisone has been used in the treatment of cerebral salt-wasting syndrome. It is used primarily to replace the missing hormone aldosterone in various forms of adrenal insufficiency such as Addisons disease and the classic salt-wasting (21-hydroxylase deficiency) form of congenital adrenal hyperplasia. Due to its effects on increasing Na+ levels, and therefore blood volume, fludrocortisone is the first-line of treatment for orthostatic intolerance and postural orthostatic tachycardia syndrome (POTS). It can be used to treat low blood pressure.Fludrocortisone is also a confirmation test for diagnosing Conns syndrome (aldosterone-producing adrenal adenoma), the fludrocortisone suppression test. Loading the patient with fludrocortisone would suppress serum aldosterone level in a normal patient, whereas the level would remain elevated in a Conns patient. The fludrocortisone suppression test is an alternative to the NaCl challenge (which would use normal saline or salt tablets).
