Allergy pills Suprastin
Indications for which Suprastin tablets are prescribed and taken for allergies:
- allergic conjunctivitis
- vasomotor rhinitis
- hives

Suprastin tablets can be white or white-gray, completely or almost odorless. Excipients that are part of the drug: lactose monohydrate, potato starch, sodium carboxymethyl starch (type A), talc, gelatin, stearic acid.
When taken into the body, Suprastin is quickly absorbed into the bloodstream. Approximately 2 hours after taking the drug, its maximum concentration in the blood occurs. But the therapeutic effect is observed already 15-30 minutes after taking it, and it lasts about 6 hours.
How to take Suprastin for allergies?
Before you start taking Suprastin tablets for allergies, you need to consult a doctor. After all, the dosage of treatment, as a rule, directly depends on the severity of the disease, age and weight of the patient. The maximum dose should not exceed 2 mg / kg of the patient's body weight. The standard scheme described in the instructions for this drug is the following dosage: adults, during meals, without chewing, should take 1 tablet (25 mg) 3-4 times a day, with a sufficient amount of water.
By the way, when using Suprastin for allergies, you should avoid drinking ethanol, or, more simply, alcohol. In addition, if possible, you should refrain from potentially dangerous activities that require increased attention.
Elderly, exhausted patients should be careful when taking Suprastin for allergies. Because such patients most often experience side effects. People with impaired liver function will probably need to reduce the dosage. And patients with kidney problems will have to change the regimen of taking the drug and reduce its dose.
It is also necessary to remember: Suprastin, especially at the initial stage of treatment, can cause drowsiness, fatigue and dizziness. Therefore, it is better to refrain from driving a car.
Suprastin for children from allergies
Contraindication to the use of Suprastin for allergies is the early age of the patient. Therefore, it is not recommended for newborns under 1 month to take Suprastin for allergies.
For children from 1 to 12 months, the dosage should not exceed 6.25 mg 2-3 times a day (1/4 tablet). Children aged 1 to 6 years can be given 8.3 mg (1/3 tablet) of the drug 2-3 times a day. It is recommended to pre-grind the tablets to a powder state and dissolve it in water or milk formula. It should not be forgotten that Suprastin can cause drowsiness and lethargy in children. In such cases, children should be given the opportunity to sleep more, rather than trying to wake them up in any way possible.
The dosage of the drug for children aged 7-14 years is 12.5 mg (half a tablet), also 2-3 times a day.
Use of Suprastin during pregnancy
Until now, doctors have not come to a consensus on whether Suprastin can be taken for allergies during pregnancy. There have been no adequate and well-controlled studies on the use of antihistamines during pregnancy. Therefore, the drug can be used by pregnant women (especially if we are talking about the first trimester and the last month of pregnancy) only in cases where the benefit outweighs the possible risk to the fetus. This is because some components of Suprastin can pass the placental barrier. And little is known about how they will affect the development of the baby. Very rarely, however, doctors make an exception and prescribe Suprastin for allergies to pregnant women. But it is important to remember that this is done as an exception. Therefore, using the drug at your own discretion is dangerous for the health of the baby.
If there is a need to use the drug during lactation, then you need to consider the option of stopping breastfeeding the baby.
Contraindications to the use of Suprastin
When using Suprastin for allergies, you need to remember a number of contraindications that this drug has. First of all, we are talking about hypersensitivity of the body to its components. It is also not recommended to take Suprastin for allergies to patients who have closed-angle glaucoma, prostatic hyperplasia, respiratory failure. An acute attack of bronchial asthma and pregnancy are also contraindications to the use of Suprastin. In addition, this drug is contraindicated with the simultaneous use of MAO inhibitors. And you should not give it to small children who are under 1 month old. Suprastin for allergies should be prescribed and used with caution in case of peptic ulcer of the gastrointestinal tract.
Side effects of Suprastin
Before you start using Suprastin for allergies, you should realize that, like any other drug, it can cause side effects. Although they happen extremely rarely. Most often, they manifest themselves as dizziness, weakness, drowsiness, dry mouth. Nausea, diarrhea, gastralgia and impaired coordination of movements are also possible, although quite rarely.
From the cardiovascular system, side effects may manifest themselves as a decrease in blood pressure, tachycardia and arrhythmia. Other side effects of the body include: difficulty urinating, muscle weakness, increased intraocular pressure, photosensitivity.
If any of the above symptoms occur, you should stop taking Suprastin and consult a doctor.
Overdose
In children and adults, an overdose of Suprastin usually manifests itself differently. In children, in such cases, agitation, anxiety, hallucinations occur. Athetosis, ataxia, convulsions, pupillary immobility are also possible. Then - vascular collapse and even coma. In adults, an overdose of Suprastin manifests itself as depression, inhibition, hyperthermia. In addition, symptoms of an overdose are also psychomotor agitation, convulsions and coma.
In cases of Suprastin overdose, it is necessary to immediately wash out the stomach and take activated carbon. In addition, symptomatic therapy will probably be required: taking antiepileptic drugs, caffeine, phenamine. In extreme cases, resuscitation measures cannot be avoided.
Interaction of Suprastin with other drugs
When using Suprastin for allergies, it should be remembered that it cannot be combined with all drugs. Thus, Suprastin enhances the effect of drugs for general anesthesia, sleeping pills, sedatives, opioid analgesics and local anesthetics. Tricyclic antidepressants enhance the m-anticholinergic and depressant effect on the central nervous system. In turn, caffeine and phenamine, on the contrary, reduce the depressant effect on the central nervous system. Suprastin is generally incompatible with ethanol.
Storage conditions and shelf life of Suprastin
The drug Suprastin for allergies should be stored in a place inaccessible to children and direct sunlight. At the same time, the air temperature in the room should not exceed 15-25 ° C. The shelf life of the drug is 5 years.
Price of Suprastin
In pharmacies, Suprastin tablets are available without a prescription. The average cost of 10 tablets is 15 UAH. A package of 20 tablets costs 25-30 UAH.
Reviews of Suprastin
Tatyana, 27, Kyiv: "Suprastin is an antiallergic drug of the so-called "old generation". Therefore, it has a fairly strong sedative effect. If possible, I would recommend using new-style antihistamines. If they have a sedative effect, it is much weaker than Suprastin."
Bogdan, 31, Kyiv: “I was tormented by allergies again. A friend recommended Suprastin. I found it in the nearest drugstore. I was surprised by the price: 15 hryvnia for 10 tablets – I haven’t seen that in a long time. At that time, I doubted whether it would help… I came home, took one tablet as instructed. Within an hour, I felt noticeable relief. By the way, I didn’t take any more, there was no need. One tablet was enough. True, not everything is so cloudless – side effects of the tablets, such as drowsiness, dizziness and dry mouth still appeared. But I don’t think it’s such a critical factor, especially considering the price of Suprastin and its almost lightning-fast action.”
Oksana, 36, Kharkov: “I have been allergic since birth. So I have been “familiar” with Suprastin for a very long time. I drank and drink it myself, and I give it to my children when necessary. A couple of months ago, my son had an allergy, I took him to an allergist, and she said: take a histamine, but not Suprastin...” Like, don’t get carried away with it. And this is despite the fact that she treated me with Suprastin from a very young age...”
Natalia, 38, Mariupol: "Suprastin has plenty of pros and cons. But I chose and will choose it to combat allergic reactions. For example, it is simply irreplaceable when vaccinating children. We always use Suprastin for routine vaccinations. We take 1/4 of a tablet two days before and one day after. In general, for me, this is a time-tested remedy."
