Thyronorm 25 mcg Tablet: Uses, Side Effects and Dosage

Hypothyroidism happens when the thyroid gland cannot produce the required amounts of thyroid hormones. While it may seem like a small issue at first, it is not. One has to remember that unlike the various other organs in our body, the thyroid gland (a tiny, butterfly-shaped organ located at the base of the neck) secretes hormones that regulate the metabolism — a process that affects how the body makes use of energy, apart from controlling other functions. A lack of thyroid hormone in the body can lead to the body’s functions becoming sluggish.

With that in mind, let’s look at some of symptoms of hypothyroidism, which can develop slowly and be mistaken for other conditions like mood swings:

For those above the age of 60:

  1. Heavy menstrual periods (in women)
  2. Fatigue
  3. Sensitivity to cold temperatures
  4. Dry skin
  5. Weight gain
  6. High cholesterol levels
  7. Thinning hair
  8. Trouble sleeping
  9. Difficulty concentrating
  10. Depression
  11. Constipation
  12. Pain or swelling of the joints
  13. Muscle weakness

For infants:

  1. Constipation
  2. Frequent choking
  3. Jaundice (yellowing of the skin and whites of the eyes)
  4. Puffy face

For teens and children:

  1. Coarse, dry hair or skin
  2. Poor growth or short stature
  3. Weight gain
  4. Muscle cramps
  5. Increased menstrual flow for girls
  6. Delayed mental development
  7. Slow reaction time
  8. Delayed puberty

If someone is suffering from some of the common symptoms of this condition, like hoarse voice, constipation, fatigue and dry skin, they can turn to the doctor for help, who will either take a physical exam, imaging scan, or blood test to reveal if the patient is suffering from hypothyroidism. With this in mind, we will have a look today at one of the medicines to help combat this condition, called Thyronorm.

Thyronorm Dosage

Thyronorm should be taken in the dose and time as suggested by the physician. The tablet must be swallowed as whole and must not be chewed or crushed for any reason. Completing the dose is important else the condition could continue worsening. It should be remembered that a patient, if he/she is under any other kind of medication, should inform the physician of the same. Sometimes, suffering from some other health issues can lead to susceptibility to side effects, so informing the doctor of any such conditions is necessary. Sometimes, the patient’s present health condition and medical history is also taken into account when deciding upon the dose. For best results the tablet should be taken on an empty stomach.

If dose is missed, then one should take it as soon as they remember, but if it is too close to the next dosage time, then it should be skipped. If an overdose occurs, then the doctor must be called immediately.
