Levothyroxine Sodium Side Effects

What is Levothyroxine Sodium?

Levothyroxine sodium is the synthetic form of thyroxine, naturally produced by the thyroid gland. The thyroid hormone helps in improving the metabolism of the body. It is also used for the growth and development of the bones and the brain. A Levothyroxine sodium dosage is recommended when the body is not able to produce natural thyroxine. This condition is called Hypothyroidism. The common brand names for levothyroxine sodium are Eltroxin, Levoxyl, Synthroid, Unithroid and Levothroid.

Dosage of Levothyroxine Sodium:

The dosage of levothyroxine sodium can vary according to the patient’s condition. The maximum dosage can be around 400 mcg. The doctor has to adjust the dosage by monitoring the patient’s condition periodically. It should be taken on an empty stomach at least an hour before meals. This will help in the maximum absorption of the drug.

  1. I was on 0.25 mg on levothyroxidine for about twenty days. I only realised how miserable I felt since I started taking it those pills after two consecutive huge headhaches when waking up in the morning.

    I couldn't even get out of bed and the headhache wasn't going not even after I took some aspirine.

    My heart was pulsing so firmly I could see my pijama shaking after every beat of my heart.

    My mouth was dry and with a weird taste. I was really scared because I couldn't understand why I felt so bad. My wife wanted to call an ambulance.

    And on this occasion while trying to figure out was I was feeling so bad my wife questioned the side effects of levothyroxidine. She had a look at the patient leaflet and googled "levothyroxidine side effects" and she found out that I was having several of the side effects.

    I stopped taking the medication on the same day. And i felt all right the day after but for a few days when the place was quite and therefore at night in bed I could hear "white noise" in my ears, like the noise of a washing machine, an intermittently an continous noise and I realised it had the rythme of my heart. For a few days I could feel that the area in my head where the headhache was quite sore, sometime a bit of pain was coming back but not so strong.

    Today 20 days later my head feel better and that noise in my ears has gone. But i also have a massive confusion in my head and I have realised that everyitme someone start a conversation with me or ask me something I have to ask to repeat again what he is saying. this is getting embarassing and it also worries me very much. I also feel emotinally drain . My gp (the one who prescribed me those damned pills) is completely useless and I will see a private doctor.

    I feel like I was prescribed something highly toxic which has messed up my system.
