hi,
thank you for putting up your query on HCM.
as per your history, you have urticarial
rash or
hives.
-- yes, they can occur as a side effect of potassium. I would recommend you to stop taking potassium supplements.
-- also, I would request you to notice, if you have taken any sour food, or milk products such as yoghurt, tomato, lemon, brinks etc.
-- I would request you to avoid these foods for at least 4 weeks.
-- take levocetrizine twice a day and tab
ranitidine 150 mg twice a day before food.
-- also, you may apply soothing lotion such as
calamine lotion over the lesions.
consult a dermatologist nearby, it it persists or worsen.
wishing you good health.
thank you.
