Preparations based on loratadine:

  • reduce capillary permeability;
  • prevent the formation( or increase) of edema;
  • relieve smooth muscle spasms.

Suppressing the action of histamine reduces itching, has a anti-exudative effect.

The duration of the drug's effect is 24 hours, while there is no effect on the nervous system.

The duration of treatment must be determined by the doctor - this depends on the individual response and the reason for the start of the therapeutic course.

Loratadine Tablets

The initial dosage for such a dosage form is what doctors call 5 mg, which is half a tablet. It is especially relevant for patients with liver disease and having hypersensitivity. With good response, the dose to persons over the age of 12 years is increased to 10 mg. A pill is drunk before meals or 1–1.5 hours after it, washed down with a small amount of warm water. Chew is not necessary. Separate with a knife if necessary. In the absence of positive dynamics after 3 days the drug is canceled.

Loratadine syrup

According to official instructions and medical statistics, in the form of a syrup, this medicine is used mainly in children, or those who are lactose intolerant. It is prescribed in the same dosages as the tablets - this is 10 mg of the active substance( which is 10 ml or 2 tsp. Of syrup) per reception for patients older than 12 years old and weighing more than 30 kg. For liver failure, it is recommended to drink 5 ml of syrup daily or 10 ml every other day. Reception is carried out before a meal, the medicine needs to be taken with water.

Loratadine for children

In infants, this medicine is not used in any form until they reach the age of 2 years, although some manufacturers( for Loratadine "Teva", "Stoma", etc.) increase the border to 3 years. The dosage is determined by the weight of the small patient - if it is less than 30 kg, it is impossible to give more than 5 mg at a time( the amount of active substance).For syrup it is 5 ml, for pills - 1/2 pcs, but with such weight it is necessary to carry out the treatment under the supervision of a pediatrician. The standard dosage of a single dose for children weighing more than 30 kg and aged from 2 to 12 years:

  • syrup - 1-2 tsp, i.e.5-10 mg;
  • tablets - 5 mg( half pill), but with good tolerability and strongly pronounced allergy symptoms, you can take 10 mg( whole pill).

Special instructions

The speed of action( gaining the maximum concentration of the active substance) is reduced in the elderly and those whose liver function is impaired, especially if it is an alcohol effect. However, dosage adjustment in these situations is not required. It is important to remember a few points:

  • Syrup should be used with caution in diabetics due to the presence of refined sugar in the composition.
  • The mental concentration from taking Loratadine does not worsen, but drowsiness may appear in some patients and the emergence of a dose-dependent sedation is not excluded.
  • Due to the presence of lactose tablets, they can be dangerous for people with intolerance to this substance, lactase deficiency and problems with the absorption of lactose or galactose.
  • Before conducting allergic tests requires the abolition of any antihistamines for a week.

Loratadine during lactation

If it is necessary to treat with Loratadine during lactation, feeding is stopped for 48 hours.

Drug Interactions

While taking Loratadine, the concentration of erythromycin decreases by 15%, and ketoconazole increases the level of the active metabolite H1-blocker histamine in the blood plasma. A similar pattern is observed when combined with protease inhibitors. Separately, it is necessary to take into account the risk of increasing the dose-dependent sedation during the reception:

  • tricyclic antidepressants;
  • hypnotics;
  • neuroleptics;
  • other H1-histamine blockers.

Loratadine and Alcohol

According to official instructions, the depressant effect of alcohol on the nervous system does not provoke Loratadine. However, their combination is undesirable, since the effect of the therapy will be reduced, and the toxic effect on the liver cells will increase. Studies have shown that the simultaneous use of alcohol and histamine H1-blockers leads to a slower metabolism of ethanol.

Side Effects of

Reviews

Galina, 32 years old

Allogy allergy pills Stoma or Teva always keep inptechke - a few years already save the whole family. There is no difference between these options, buying what is present at a particular moment in the sale. Allergy symptoms are removed within 24 hours, drowsiness, as from Suprastin, no. When I react to drugs, I take pills for 3 days, with seasonal allergies - 5 days.

Alena, 29 years old

I don’t really trust the reviews on medications - I need to select with a doctor, not from someone else’s opinion, but I changed myself with Loratadin: I was looking for an inexpensive antihistamine and found… for 20 rubles. The effect is impressive! She took it first with ARVI to remove the mucosal edema, then gave the child a reaction to pollen - the action of the pills is almost instant!

Ilona, ​​35 years old

I consider the mildest among all the tested antihistamine medications for children Loratadine for children: the syrup gave even to the baby( after consulting with the doctor) when the teeth got up - the dosage was 1/2 tsp. Older pills( 4 years old) were already prescribed in half, at the height of the seasonal response to pollen and after vaccination - they were well tolerated.
