Urticaria, though not life threatening, can affect normal everyday life – especially the rashes from chronic urticaria which cause irritating itches in the long run, so much so that it can affect the quality of life including your sleep. Quick and effective treatment is, therefore, essential in improving an urticaria sufferer’s quality of life.

Getting to Know Chronic Urticaria

Chronic Urticaria exhibits rashes, or hives, that appear and reappear at least twice a week, continuously for 6 weeks or more. If the rashes remain for a length of time, it may darken the skin and some small bleeding. Moreover, urticaria can cause irritation – both physically and emotionally – which may lead to a loss of poise and self-confidence. It can also affect your ability to sleep restfully. Though it is not life-threatening, chronic urticaria could prompt other problems in the long run if left untreated

Chronic Urticaria Treatments

Treating chronic urticaria varies from case to case, depending on its cause and stimulating factors. The goal is to reduce the rashes with medication, such as:

  • Antihistamine medicine to help control the allergic reaction.  There are many different types of medication and their effects vary. As the dosage needs to be adjusted regularly over time, it is important to consult a medical specialist and you must strictly adhere to the doctor’s advice.
  • In cases with severe chronic urticaria, where antihistamine medicines are not sufficient to curb the flare-up, the doctor may consider other types of medication to arrest the cause of allergy and help improve the patient’s condition as quickly as possible.

Proper Care When Suffering with Chronic Urticaria

  • Avoid the cause of the allergy or its stimulant.
  • Strictly follow your doctor’s advice.
  • If the medication causes drowsiness which may affect work and daily life, it is important to consult your doctor for medication adjustments.
  • Do not stop taking the medicine unless directly by your doctor.
  • Do not scratch or peel off the affected skin.
  • Ensure sufficient restful sleep, and avoid late nights.
  • Avoid emotional stress.

Chronic urticaria may require a long treatment before it is under control. You should maintain a disciplined approach and take medicines as prescribed by your doctor. It is equally important to keep the regular doctor’s appointments. However, most vitally, you should sustain physical as well as emotional wellness.
