Benadryl Malaise Causes and Reviews


What is chronic fatigue syndrome?

Chronic fatigue syndrome (CFS) is a serious, long-term illness that affects many body systems. Another name for it is myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). CFS can often make you unable to do your usual activities. Sometimes you may not even be able to get out of bed.

What are the symptoms of chronic fatigue syndrome?

CFS symptoms can include

  • Severe fatigue that is not improved by rest
  • Sleep problems
  • Post-exertional Malaise (PEM), where your symptoms get worse after any physical or mental activity
  • Problems with thinking and concentrating
  • Pain
  • Dizziness

CFS can be unpredictable. Your symptoms may come and go. They may change over time - sometimes they might get better, and other times they may get worse.

Who gets chronic fatigue syndrome?

Anyone can get CFS, but it is most common in people between 40 and 60 years old. Adult women have it more often that adult men. Whites are more likely than other races to get a diagnosis of CFS, but many people with CFS have not been diagnosed with it.

What causes chronic fatigue syndrome?

Scientists don't know what causes CFS. There may be more than one thing that causes it. It is possible that two or more triggers might work together to cause the illness.

How is chronic fatigue syndrome diagnosed?

CFS can be difficult to diagnose. There are no tests for it, and other illnesses can cause similar symptoms. Your health care provider has to rule out other diseases before making a diagnosis of CFS. He or she will do a thorough medical exam, including

  • Asking about your health history and your family's medical history
  • Asking about your current illness, including your symptoms. Your doctor will want to know how often you have symptoms, how bad they are, how long they have lasted, and how they affect your life.
  • A thorough physical and mental status exam
  • Blood, urine or other tests
What are the treatments for chronic fatigue syndrome?

There is no cure or approved treatment for CFS, but you may be able to treat or manage some of your symptoms. You, your family, and your health care provider should work together to decide on a plan. You should figure out which symptom causes the most problems, and try to treat that first. For example, if sleep problems affect you the most, you might first try using good sleep habits. If those do not help, you may need to take medicines or see a sleep specialist.

Strategies such as learning new ways to manage activity can also be helpful. You need to make sure that you do not "push and crash." This can happen when you feel better, do too much, and then get worse again.

Since the process of developing a treatment plan and attending to self-care can be hard if you have CFS, it is important to have support from family members and friends.

Don't try any new treatments without talking to your health care provider. Some treatments that are promoted as cures for CFS are unproven, often costly, and could be dangerous.

Benadryl Malaise Reviews

Sun, 04 Sep 2011

Can I die from taking this many. Is it physicly addicting? Sorry about my spelling.

Mon, 18 Jul 2011

I loved these strips. I have had allergic reactions to my own allergy shots. After waiting at the Dr.'s office for 15 minutes after my allergy shot, I leave to go shopping. Sometimes I can feel a little thickening in my throat, similar to when I've had a really bad reaction and had to go to the ER for help, or went back to the Dr.'s office for a shot of epinepherine. When I feel just a small reaction beginning, I have put one of the Benadryl Quick Dissolve Strips on my tongue. I get a pretty fast result and I can continue shopping rather than worrying about a worse reaction.

Now, when I went to buy more of this product, it isn't available at any local stores, or on line at safe sites. Each store tells me that people are coming in and wanting them and getting upset when they can't find them.

Why were these strips taken off the market?
