Thyronajod® is a preparation for the treatment of thyroid disorders, more precisely the treatment of an underactive thyroid (Hypothyroidism) or a goiter (goiter) without thyroid dysfunction.
The manufacturer is the company Sanofi-Aventis in Frankfurt am Main.
The thyroid is located in front of the windpipe on the human neck. Usually it is not visible or palpable.
A palpable enlargement of the thyroid gland is called goiter and often occurs in combination with dysfunction of the thyroid gland.
The hormone made by the thyroid gland is called thyroxine. Thyroxine generally stimulates and accelerates the metabolism in the body.
If the thyroid function is out of balance, either an underactive thyroid arises (Hypothyroidism, "Hypo" = "under") in which too little thyroxine is produced or an overfunction, which is then called Hyperthyroidism ("Hyper" = over) and in which too much thyroxine is produced.
Thyronajod® replaces the body's own thyroxine in the event of a thyroxine deficiency and is therefore used as the drug of choice for an underactive thyroid.
Since a goiter can also be caused by an iodine deficiency, the iodide contained in Thyronajod® can additionally support the thyroid, because it needs iodine to produce thyroxine and increases in size with a deficiency of iodine.

The included Levothyroxine replaces the body's own thyroxine, which is produced in a Hypothyroidism there is too little in the body.
iodine is essential for the formation of thyroid hormones, as it is an important component of thyroxine.
Thus, the thyroid contained in Thyronajod® can supply additional iodine if this e.g. owing to Iodine deficiency is enlarged or a hypofunction has developed.

A few rare skin diseases that are triggered by iodine, such as a special form of vascular inflammation, should also lead to the avoidance of Thyronajod®.
Before taking Thyronajod® must be excluded that the thyroid gland so-called autonomous areas having. These areas produce uncontrolled thyroxine and the production rate would increase uncontrollably through the administration of additional Thyronajod®.
If there is a suspicion of a so-called autonomous area, this suspicion should be clarified by further examinations in order to be able to take Thyronajod® depending on the result.
Logically, Thyronajod® should not be taken if you have your own overproduction of thyroxine in the context of a Hyperthyroidism suffers.

The reason for this is that an increased metabolism and a stimulation of the circulatory system are always associated with more work for this system. Parts of this system that have already been damaged can possibly fail due to this additional load and this can lead to life-threatening situations such as Heart attack, cardiac arrhythmia, heart failure or even high blood pressure crises come.
These diseases should be monitored closely while taking Thyronajod® regularly.

In the course of the circulatory stimulation it can be too Palpitations from a heartbeat that is too fast (Tachycardia) up to insufficient supply of the entire heart with heart attack-typical chest pain, which then often radiates into the left arm. It can also Cardiac arrhythmias occur.
Furthermore, it can become one through the extreme stimulation of the metabolism in the entire body Feeling hot come that from excessive sweat can be accompanied.

In this case, the dose of the medication must be adjusted by the doctor for the duration of the therapy with Thyronajod®.
Furthermore, switching between different preparations for the treatment of hypothyroidism is only permitted under medical supervision, since the same ingredients can differ considerably in terms of their duration of action and the type of metabolism in the body.
For certain drugs, it is also important to keep a time interval of 4-5 hours so that the absorption from the intestine could otherwise influence each other.
These include drugs for Lowering blood lipids, some medicines for high levels of cholesterol in the blood (called Bile acid sequestrants) or Remedies for high blood potassium levels.
An intake interval of two hours is with aluminum-containing Heartburn preparations necessary.
The decisive factor for all of these preparations is their absorption in the intestine. Many drugs are absorbed into the intestines in the same way. If there are too many active ingredients in the intestine, they compete and it can no longer be guaranteed that all active ingredients will be adequately absorbed in the body.
