Medication for Treating HYPER Periodic Paralysis
It's important to get Hyperkalemic Periodic Paralysis treatment because even though the muscle weakness attacks are usually temporary, it's possible that they can eventually cause permanent muscle weakness.
One thing you can do is to try to avoid things that trigger the episodes. For example, you may need to cut down on your potassium intake. Managing your stress levels is something else you can do to reduce the likelihood of an episode since stress is a trigger. Writing in a journal about things that make you feel stressed is a good first step to take in managing stress.

Acute Hyperkalemic Attacks
Simple Carbohydrates
Glucose or other carbohydrates (sugars) given during an attack may reduce the severity of the symptoms. High carbohydrate food (candy bar) or drink (sugar cola, sweet tea) taken at the first sign of weakness may abort or relieve episodes.

Albuterol
Lowers the potassium. Albuterol (also known as salbutamol) is used to prevent and treat wheezing and shortness of breath caused by breathing problems (such as asthma, chronic obstructive pulmonary disease). It is also used to prevent asthma brought on by exercise. It is a quick-relief medication. Albuterol belongs to a class of drugs known as bronchodilators. It works in the airways by opening breathing passages and relaxing muscles.
