Patients who take potassium chloride long-term, i.e., are at risk for developing vitamin B-12 deficiency. Potassium supplements such as K-Dur, Micro-K, Slow-K, K-Lyte, etc. interfere with the absorption of vitamin B-12 and can eventually lead to the depletion of body stores of this crucial vitamin. 1, 2, 3
The regular colonoscopy prep can cause a hypokalemic episode in a patient with hypokalemic periodic paralysis. This colonoscopy prep, adapted to avoid hypokalemia, has been used by numerous patients with HypoKPP on the HKPP Listserv without provoking an episode afterwards.

The use of local anaesthetics on patients with periodic paralysis presents some unusual challenges. Many patients report that these agents trigger weakness or paralysis, a phenomenon which is substantiated in medical literature. Some patients also report that the agents do not produce the desired anaesthesia.
In July of 1998 we conducted a survey of 64 self-reported clinically diagnosed periodic paralysis patients, all members of the HKPP Listserv. The questionnaire underwent no formal validation process, nor was the data assessed by personnel trained in this field. The patients surveyed were drawn from several countries and across several racial/ethnic lines and backgrounds.
The Compound Muscle Action Potential (CMAP) test (aka the Exercise EMG) is now being used to diagnose the periodic paralyses. When done correctly this test is reported to positively identify 70%-80% of patients.
Familial HypoKPP Symptoms began at age of 13 years with three paralytic episodes of 48-72 hour duration.
Are your symptoms worse with your menses? No

There is little available medical literature to guide the physician in the care of the pregnant patient who has periodic paralysis. The first part of this packet consists of abstracts and quotations drawn from current literature. But this information is limited. Because Periodic Paralysis International has a number of clients who have given birth we felt it might be helpful to survey them about their experiences. The second, third and forth parts of this packet consists of case studies of women with periodic paralysis who have given birth.
