Horse,: Yes. You are taking a diuretic so take some potassium carefully because you are akso on lisinopril.

get potassium measur: Low potassium doesn't cause muscle cramps - it can cause tetany and, in extremely low levels, it can cause muscle weakness (called "periodic paralysis"). I suggest you have your potassium measured and then supplement it if it's low. Low potassium is a common cause of cardiac arrhythmias.

Why is it low?: Do you know why is it low? Is it because you're on medicines that artificially lower it? There are rare genetic conditions that can lower potassium? Or was this a random lab finding. If it was a random finding, realize potassium levels can fluctuate moment to moment. Also machines have error too. If its borderline low, don't go nuts with a high potassium diet. If it's markedly low, talk to doc!

It : It is not uncommon for people to develope allergies toward the end of a course of antibiotics. Your story is fairly typical. Your daughter has had a pretty bad allergic reaction to penicillin and should never get penicillin or Amoxicillin ever again.
Dr. Nayla Mumneh

I would avoid all penicillin related antibiotics, for at least 10 years. She may be tested then by an allergist to determine if she is still allergic to penicillin. Generally individuals revert their penicillin allergy after 10 years of non exposure.
