Use during pregnancy and breastfeeding

Use for the treatment of pregnant women and during breastfeeding is possible only if the expected benefit to the mother outweighs the potential risk to the fetus or child. You should consult your doctor.

Directions for use and doses

Place in each nasal passage. Adults are prescribed 1-3 drops of 0.05% or 0.1% solution 3-4 times a day. For children, a 0.05% solution is used: from 1 to 6 years – 1-2 drops, from 6 to 18 years – 2 drops 1-3 times a day.

For diagnostic purposes - after cleaning the nasal cavity, 3-4 drops are instilled into each nasal passage or a tampon soaked in a 0.05% solution is inserted and left for 1-2 minutes; in case of swelling of the vocal cords, administer 1-2 ml of a 0.05% solution of the drug in small doses with a laryngeal syringe; in case of bleeding, insert a tampon moistened with a 0.05% solution of the drug.

For rhinitis, the course of treatment should not exceed 5-7 days in adults and no more than 3 days in children.

As an additional drug for surface anesthesia - 2-4 drops per 1 ml of local anesthetic.

May have a resorptive effect. With long-term use, the severity of the vasoconstrictor effect gradually decreases (the phenomenon of tachyphylaxis), and therefore it is recommended to take a break for several days after 5-7 days of use.

Side effect

Nausea, tachycardia, headache, increased blood pressure, reactive hyperemia, swelling of the nasal mucosa, irritation of the nasal mucosa. Local reactions, when used for more than 1 week - swelling of the nasal mucosa, atrophic rhinitis.

Overdose

Symptoms: decreased body temperature, bradycardia, increased blood pressure.

Treatment: symptomatic.

Interaction with other drugs

Concomitant use with MAO inhibitors or within 14 days after the end of their use is contraindicated.

Slows down the absorption of local anesthetic drugs (prolongs their effect during superficial anesthesia).

Co-administration of other vasoconstrictor drugs increases the risk of side effects.

Indications for use

The nasal medication is prescribed to patients with domestic allergies. The medication acts on alpha-adrenoceptors in peripheral vessels. It slowly constricts them, while simultaneously increasing blood pressure and dilating the pupils.

Naphthyzin reduces swelling and hyperemia. The squirrels turn white. The medicinal solution also helps eliminate other unpleasant signs of allergic conjunctivitis, such as itching, the sensation of a foreign body in the eyes and increased lacrimation.

The medication is also prescribed for chronic conjunctivitis and blepharitis. Less commonly used to treat glaucoma.

When is the use of Naphthyzin in the eyes justified?

The use of a medicinal solution in the eyes is justified only for chronic and allergic conjunctivitis. For other pathologies of the optical system, the use of Naphthyzin is strictly contraindicated.

Since the nasal solution constricts the blood vessels in the eyes, thereby eliminating swelling and increased lacrimation, hyperemia, discomfort and burning, it is prescribed for the allergic form of conjunctivitis.

This effect of the drug is difficult to underestimate. After all, Naphthyzin quickly solves the problems of red eyes and irritation, restoring shine and whiteness. It quickly makes you feel better in any form of allergic conjunctivitis (seasonal, domestic or year-round).

It is recommended to use only the drug for children, since adults have a higher concentration and, accordingly, will lead to the development of glaucoma faster.

In addition, the price of Naphthyzin is significantly lower than that of ophthalmic drugs for these conditions.

Side effects

In isolated cases, taking the drug does not occur without side effects. After instillation of the medicine into the conjunctival cavity, it causes a slight tingling sensation. The burning goes away within a few minutes.

The mechanism of action of the drug can significantly reduce the patient’s quality of life. The drug affects the central nervous system, in rare cases leading to episodes of pain in the head and neck.

The drug increases systolic blood pressure, leading to mild, moderate, severe, isolated or borderline hypertension. Also leads to increased heart rate. The medicine should be taken with caution in old age, especially if there are fluctuations in blood pressure and its regular increase.

In addition, an increase in blood pressure leads to an increase in intraocular pressure. With prolonged use, you can develop a new problem called glaucoma. This fact has not been scientifically proven, but it is not excluded either.

Less commonly, Naphthyzin, when applied topically to the eyes, leads to nausea and vomiting, redness of the conjunctiva and eyelids, and swelling of the mucous membrane.

In case of an overdose of the drug, the following symptoms appear:

• drowsiness;
• insomnia;
• nervousness and overexcitement;
• dry mucous membranes;
• sand in the eyes;
• pain;
• increased sensitivity to bright light.

Long-term use not only causes an overdose, Naphthyzin leads to a deterioration in the nutrition of the eye structures, and accordingly can cause more severe conditions.

Doctors' opinion

According to doctors, the use of Naphthyzin nasal drops in the eyes is strictly prohibited. It is impossible to engage in such self-medication if a person does not know the cause of his condition.

The ophthalmologist must make a diagnosis before prescribing the drug, only in this case its use will be justified.

The medication is not at all harmless. The medicine can cause severe side effects and complications from the visual system. When prescribed by a doctor, Naphthyzin should not be used for more than 4 days, this is associated with a high risk of developing glaucoma.

The legend that the medicine is not harmful was invented by drug addicts and alcoholics who need to hide their condition by bringing the proteins back to normal. Since the medicine is available and available without a prescription in most pharmacies, these people successfully use it without knowing the consequences.

Contraindications

The drug has many contraindications in ophthalmology. It is not recommended for use in cases of increased pressure inside the eye and glaucoma. In the latter case, the use of the medication is permitted on the recommendation of an ophthalmologist.

Naphthyzine should not be used in the following conditions:

• keratoconus;
• keratitis;
• hyperfunction of the thyroid gland;
• corneal dystrophy;
• infectious pathologies;
• bacterial ulcer;
• bullous keratopathy;
• corneal erosions;
• insulin-dependent/non-insulin-dependent diabetes;
• disturbances in the functioning of the cardiovascular system;
• hypersensitivity to the components of the drug.

The use of the medicinal composition is contraindicated for more than 4 days. You cannot combine Naphthyzin with MAO inhibitors. The use of the drug is prescribed 2 weeks after discontinuation. The list of contraindications also includes age under 1 year, pregnant and lactating women.

Adequate clinical studies on the effects of the medicinal solution on the fetus and infants have not been conducted.

special instructions

With prolonged use, the medicine stops working. The active ingredient Naphthyzin is addictive. The medication stops working properly.

The vasoconstriction slows down, and the effect of the drug does not occur as quickly as at the beginning of therapy. Addiction leads to pain in the head, sleep disturbances (insomnia), an increase or decrease in heart rate and cyanosis of the skin.

In this case, you should temporarily stop taking the medicine and replace it with an analogue with a different active component.

The medication cannot be used with contact lenses. Nasal drops disrupt their transparency. Before instillation, the optics are removed and can be put on after 15–30 minutes.

Can you put it in your eyes or not?

The effect of the drops is immediate. Alcoholics and drug addicts use the medicine more often, since red proteins attract attention, and Naphthyzin quickly eliminates this symptom by narrowing the blood vessels in the eyes.

There are two types of nasal drops with a concentration of 0.1% and 0.05%. The former is not recommended for the treatment of eye diseases or masking reddened whites; it causes rapid addiction, as well as a feeling of dry mucous membranes and stinging in the eyes.

You can use 0.1% medication only as prescribed by your doctor. It is better to buy special medications designed to treat ophthalmological diseases. 0.5% remedy is prescribed for conjunctivitis of microbial origin and chronic. Drops of 0.05% are considered children's. They can be used in the treatment of eye diseases. The official instructions for the medication indicate that the use of Naphthyzin in this concentration is permitted for allergic conjunctivitis.

It should be understood that both forms of the solution increase blood pressure, including affecting intraocular pressure. If a patient’s blood pressure constantly fluctuates and he has been suffering from high blood pressure for a long time, then illiterate use of the drug will lead to serious consequences.

Due to serious side effects and complications after use, only an ophthalmologist has the right to select the drug and prescribe it. You cannot buy it yourself, much less determine the dosage.

Mode of application

The medicine can be used within 28 days after the bottle is depressurized.

To alleviate the patient's condition, Naphthyzin is prescribed in combination with other medications. The medicine is prescribed not according to the instructions, but depending on the patient’s condition and the severity of conjunctivitis.

It is recommended to use the medication 2–3 times a day, 1 drop. To do this, wash your hands with soap and unscrew the cap. Pull back the lower eyelid and drip the drug into the conjunctival cavity, carefully pressing on the bottle so as not to squeeze out a lot of the solution.
