How often do we resort to self-medication without thinking, especially if we have to treat a common runny nose. What would seem simpler: in any pharmacy there is a wide variety of vasoconstrictor drops , which, after instillation into the nose, cause vasoconstriction and, as a result, relieve swelling and reduce mucus formation. And here it is, the longed-for freedom of nasal breathing for several hours.

Few people think that vasoconstrictor drops do not have a therapeutic effect, but only relieve symptoms for a short time. After the medication wears off, the swelling reappears, so it makes no sense to treat a runny nose of any origin only with vasoconstrictor drops. This is only an auxiliary therapy that helps ease nasal breathing during the treatment period.

What is naphthyzin and why is it dangerous?

Naphthyzin are short-acting vasoconstrictor drops that easily penetrate both the wall of the vessels of the nasal cavity and the general bloodstream, exerting a vasoconstrictor effect on all vessels in general, and therefore is contraindicated in cases of severe hypertension.

Now on the pharmaceutical market there are many vasoconstrictor drops that differ in composition: there are both short- and long-acting drugs, but unfortunately, all of them can cause symptoms of naphthyzine poisoning .

Even less do we think about the fact that drops can be life-threatening, especially when used in children. An overdose of drops, exceeding the dose of the drug by 3-4 times, can cause such a serious complication as naphthyzine poisoning. As a rule, this happens when the age-specific concentration of the solution is not observed, or when the visual number of drops that have entered the nose is difficult, or simply when they are used uncontrolled, when the child does it himself or the drops are within his reach.

Signs of mild or initial stages of naphthyzine poisoning:

  • increased arousal

  • dizziness
  • abdominal pain

If the drug continues to accumulate in the body or the overdose was more significant, then the symptoms worsen: the heart rate slows down significantly, blood pressure drops, and severe lethargy, weakness, and drowsiness appear. At the same time, the child is sleeping, but this sleep is unnaturally deep, the tone in the arms and legs drops (if you lift them, they fall like “lashes”), confusion, a decrease in body temperature, the skin becomes pale, cold and damp, breathing is shallow.

What to do if these symptoms appear while using vasoconstrictor drops?

First of all, call an ambulance. Before the doctor arrives: stop taking the drug, cover the patient with a blanket, give him a warm drink, measure the temperature, blood pressure and try to maintain consciousness, do not let him fall asleep. Considering the seriousness of the consequences, do not use vasoconstrictor drops, especially if the child is sick; be sure to consult an otolaryngologist to prescribe treatment and follow-up over time. Remember that most vasoconstrictor drops can be used for 2-3 to 5-7 days; this is a short period of time that must be used to treat the inflammation process.

In ENT clinic number 1, in order to minimize the number of prescriptions of drug therapy, they will help you relieve swelling and inflammation using unique highly effective physiotherapeutic techniques, such as: USOL therapy of the nasopharynx, photochromotherapy of the nose, laser therapy of the nose, which will allow in the shortest possible time not only to relieve swelling, but and the cause of inflammation.
