Phenergan is a drug for symptomatic therapy of the sharp respiratory diseases relieving the course of the allergic reaction. The most important pharmacological peculiarity of Phenergan is its strong antihistamine activity. It blocks histamine H1 receptors which directly influence on the severity of the allergic reaction.
Besides the antiallergic action Phenergan has antiemetic, strong sedative, antipruritic action, provides a serious effect to the central nervous system. The active component of Phenergan is Promethazine on the basis of which different drugs are produced for the recovery of sleep and anesthesia.
This drug provides a broad spectrum action to the body, and therefore it is very important to follow special dosage regimen and consult a professional medical specialist before the beginning of the treatment.
The antiallergic action of Phenergan develops within 20-30 minutes after the use of the tablet and gains maximum in couple of hours. The only drawback of the drug is a short-term therapeutic effect. On the average, the action lasts from 6 to 8 hours but in the individual cases doctors indicate 12-hour effect.
