2. Important information before taking Doxycyclinum Polfarmex

When not to take Doxycyclinum Polfarmex:

• if the patient is hypersensitive (allergic) to doxycycline or other tetracycline antibiotics or any of the other ingredients of this medicine (listed in section 6);
• in infants and children under 12 years of age;
• in pregnant and breastfeeding women.

Doxycycline should not be used during tooth development (pregnancy, infants, and children up to 12 years of age), as it may cause permanent discoloration (yellow-gray-brown) of teeth, disrupt normal tooth development, and affect the skeletal system.

Warnings and precautions

Before starting treatment with this medicine, the patient should inform the doctor if they have:

• liver and/or kidney function disorders;
• porphyria (a rare disease related to disorders of porphyrin metabolism - one of the elements of red blood cells);
• myasthenia gravis (a disease characterized by excessive fatigue and muscle weakness);
• systemic lupus erythematosus (a disease with an allergic background, characterized by joint pain, skin rash, fever).

During treatment with Doxycyclinum Polfarmex, the patient should tell the doctor if:

• severe, prolonged diarrhea occurs; antidiarrheal medications or other medications that slow down intestinal motility should not be used;
• symptoms of a new bacterial infection or fungal infection occur (e.g., persistent itching, skin redness), especially during prolonged antibiotic treatment.

In diseases where syphilis is suspected, the doctor will recommend diagnostic tests before starting treatment.
Tetracyclines, including doxycycline, may cause hypersensitivity to light. During treatment, the patient should avoid sunbathing or artificial UV radiation (e.g., solarium) due to the risk of photosensitivity, which may manifest as skin redness, swelling, blisters. If such symptoms occur, the medicine should be discontinued immediately and the doctor consulted.
To avoid esophageal inflammation and ulceration, the medicine should be taken at least 30 minutes before bedtime and washed down with a glass of water. See "Method of administration" in section 3.

Doxycyclinum Polfarmex and other medicines

The patient should tell the doctor about all medicines taken recently, including those available without a prescription.
In particular, the doctor should be informed if the patient is taking:
Antacids (containing multivalent ions of aluminum, calcium, magnesium, as well as products containing iron, zinc, or bismuth ions) may reduce the absorption of doxycycline. Therefore, these food or medicinal products should be taken at least 2 to 3 hours after taking doxycycline.
Sedatives (barbiturates); rifampicin (an antitubercular medicine); carbamazepine, phenytoin, primidone, phenobarbital (antiepileptic medicines) or cyclosporine (a medicine used after organ transplantation) may reduce the effectiveness of Doxycyclinum Polfarmex.
Antibiotics from the penicillin group and other antibiotics may reduce the effectiveness of Doxycyclinum Polfarmex.
Cephalosporins may enhance the toxic effects of Doxycyclinum Polfarmex.
Methoxyflurane (a medicine used in general anesthesia) may increase the toxicity of Doxycyclinum Polfarmex and cause severe kidney damage.
Anticoagulants (e.g., warfarin) may enhance the effect of Doxycyclinum Polfarmex.
Oral antidiabetic medicines (sulfonylurea derivatives) may enhance the effect of Doxycyclinum Polfarmex.
Oral contraceptives may reduce the effectiveness of Doxycyclinum Polfarmex, so during treatment with doxycycline, it is recommended to use additional non-hormonal contraceptive methods.
Theophylline (used, e.g., in asthma) may increase the frequency of gastrointestinal side effects when taken with Doxycyclinum Polfarmex.
Doxycyclinum Polfarmex may affect urine catecholamine test results. If the patient is to undergo any tests, they should inform the doctor about taking Doxycyclinum Polfarmex.

Doxycyclinum Polfarmex and alcohol

The medicine contains lactose monohydrate. If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.
The medicine contains less than 1 mmol (23 mg) of sodium per hard capsule, which means it is considered "sodium-free".

3. How to take Doxycyclinum Polfarmex

This medicine should always be taken exactly as prescribed by the doctor. If you have any doubts, you should ask your doctor or pharmacist.
The medicine is taken orally.
The doctor will determine the appropriate dosage of the medicine, depending on the disease and the patient's condition, as well as current official guidelines for the use of antibacterial medicines. Before starting treatment with doxycycline, a test will be performed to isolate the microorganism causing the infection and its antibiotic susceptibility. Treatment may be initiated before the results of the antibiotic susceptibility test are available.
After receiving the results, it may be necessary to change the medicine.

Recommended dosage for adults and children over 12 years of age

On the first day, 200 mg of doxycycline is administered in a single dose or in 2 divided doses (100 mg every 12 hours), and then a maintenance dose of 100 mg per day is administered.
In severe infections, 200 mg per day is administered throughout the treatment period.

Recommended dosage for certain infections

Sexually transmitted diseases

Gonococcal uncomplicated infections (except for rectal infections in men); uncomplicated urethral, cervical, or rectal infections caused by Chlamydia trachomatis;non-gonococcal urethritis caused by Ureaplasma urealyticum:100 mg twice a day (every 12 hours) for 7 days.
Acute epididymitis and prostatitis caused by Chlamydia trachomatisor Neisseria gonorrhoeae:100 mg twice a day (every 12 hours) for 10 days.
Primary and secondary syphilis: in patients allergic to penicillin (except for pregnant women), 200 mg twice a day for 2 weeks, as an alternative treatment to penicillin.

Dosage for prevention of infections

Malaria

In adults and children over 12 years of age, 100 mg per day is administered. Prophylaxis should be started 1-2 days before the planned trip to malaria-endemic areas. Doxycycline should be administered throughout the stay in the malaria-endemic area and for 4 weeks after leaving the area. You should consult current guidelines for malaria prevention in the specific geographic region.

Traveler's diarrhea

In adults, 200 mg is administered on the first day of travel (in a single dose or 100 mg twice a day, every 12 hours), and then 100 mg per day during the stay, for no longer than 21 days.

Leptospirosis

200 mg is administered once a week during the stay in the area where leptospirosis occurs (for no longer than 21 days) and once, 200 mg after the trip.

Dosage for children under 12 years of age

The medicine should not be used in children under 12 years of age (see also section 2).

Dosage for elderly patients

Dose adjustment is not necessary. However, it should be remembered that these patients are more susceptible to gastrointestinal side effects, so they should strictly follow the recommendations described below in the "Method of administration" section.

Dosage for patients with renal and/or hepatic impairment

In patients with renal impairment, dose adjustment is not necessary.
In patients with hepatic impairment, caution should be exercised. In these patients, especially during prolonged treatment, high doses, or concomitant use of other hepatotoxic medicines, regular monitoring of liver function is recommended.

Duration of treatment

The duration of treatment is always determined by the doctor. The antibiotic is usually administered for 24-48 hours after the symptoms have resolved.
In infections caused by β-hemolytic streptococci group A, treatment usually lasts for at least 10 days.

Method of administration

The capsules should be swallowed whole, washed down with a glass of water.
To prevent possible irritation of the throat or intestines, the capsules should be taken in a sitting or standing position, at least 30 minutes before bedtime (it is essential that the patient does not lie down immediately after taking the capsule).
Patients who experience persistent gastrointestinal side effects may be advised by their doctor to take the medicine with food.
Taking doxycycline with food reduces the occurrence of gastrointestinal side effects and does not significantly affect its absorption.
If the patient feels that the effect of the medicine is too strong or too weak, they should consult their doctor.

Use of a higher than recommended dose of Doxycyclinum Polfarmex

Symptoms of doxycycline overdose are: fever, facial redness, dizziness, sometimes fainting. If these symptoms occur, the medicine should be discontinued immediately and the doctor consulted.
