1. What is Claritromicina Farmalider and what is it used for

Claritromicina is a medicine that belongs to the group of macrolide antibiotics and acts by eliminating bacteria.

"Antibiotics are used to treat bacterial infections and are not effective against viral infections such as the flu or the common cold.

It is essential that you follow the instructions regarding the dose, administration interval, and treatment duration indicated by your doctor.

Do not store or reuse this medicine. If you have any leftover antibiotic after finishing the treatment, return it to the pharmacy for proper disposal. Do not throw away medicines via wastewater or household waste."

Claritromicina Farmalider 500 mg film-coated tablets are used for the treatment of infections caused by susceptible germs in adults and adolescents from 12 to 18 years old:

-Infections of the upper respiratory tract, such as pharyngitis (infection of the pharynx that causes sore throat), tonsillitis (infection of the tonsils), and sinusitis (infection of the paranasal sinuses located around the forehead, cheeks, and eyes).

-Infections of the lower respiratory tract, such as acute bronchitis (infection and inflammation of the bronchi), exacerbation of chronic bronchitis (worsening of prolonged or recurrent lung inflammation), and bacterial pneumonia (inflammation of the lungs caused by bacteria) (see section 2 warnings and precautions).

-Infections of the skin and soft tissues, such as folliculitis (infection of one or more hair follicles), cellulitis (acute inflammation of the skin), and erysipelas (a type of skin infection) (see section 2 warnings and precautions).

-Gastric and duodenal ulcers.

-And in the prevention and treatment of infections produced by mycobacteria.

2. What you need to know before you take Claritromicina Farmalider

Do not take Claritromicina Farmalider:

• If you are allergic to clarithromycin, other macrolide antibiotics such as erythromycin or azithromycin, or to any of the other components of this medicine (listed in section 6).

• If you have an irregular heartbeat.
• If you have severe kidney and liver problems.
• If you are taking ergotamine or dihydroergotamine or using ergotamine inhalers for migraine while taking clarithromycin. Consult your doctor for alternative medications.
• If you are taking medications called terfenadine, astemizole (medication for hay fever or allergies), cisapride, or domperidone (used for stomach problems) or pimozide (medication used to treat certain psychiatric disorders), as taking these medications with clarithromycin can cause severe heart rhythm disturbances. Consult your doctor for alternative medications.
• If you are taking ticagrelor (to prevent the formation of blood clots in your veins and used in heart attacks and other heart problems), ivabradine, or ranolazine (for angina pectoris).
• If you are taking other medications known to cause severe heart rhythm disturbances.
• If you are undergoing treatment with oral midazolam (for anxiety or to help fall asleep).
• If you have abnormally low potassium levels in your blood (hypokalemia).
• If you or a family member have a history of heart rhythm disorders (ventricular cardiac arrhythmia, including Torsade de Pointes) or abnormalities in the electrocardiogram (ECG, electrical record of the heart) called "QT prolongation syndrome".
• If you are taking medications called lovastatin or simvastatin (to lower cholesterol levels), as the combination of these medications can increase the occurrence of side effects. Consult your doctor for alternative medications.
• If you are taking colchicine (for gout).
• If you are taking a medication with lomitapide.
• If you have abnormally low levels of potassium or magnesium in your blood (hypokalemia or hypomagnesemia).

Warnings and Precautions

Consult your doctor or pharmacist before starting to take Claritromicina Farmalider:

• If you have heart, kidney, or liver problems.
• If you have or are prone to fungal infections (e.g., thrush).
• If you are pregnant or breastfeeding.
• If you are taking medications known as colchicine, triazolam, midazolam (for anxiety or insomnia), lovastatin, simvastatin.
• If you are diabetic and taking hypoglycemic agents (medications to lower blood sugar levels, such as nateglinide, pioglitazone, rosiglitazone, repaglinide, or sulfonylureas) and/or are being administered insulin, as it may lower blood sugar levels too much. Careful monitoring of glucose levels is recommended.
• If you are taking a medication called warfarin (blood anticoagulant).
• If you have myasthenia gravis, a condition where your muscles weaken and tire easily.
• If you develop severe or prolonged diarrhea during or after taking clarithromycin, consult your doctor immediately.

If any of these situations affect you, consult your doctor before taking clarithromycin.

Children and Adolescents

Do not administer this medicine to children under 12 years old; there are other presentations available for this age group (granules for oral suspension).

Elderly Patients

Since clarithromycin is eliminated by the liver and kidneys, caution should be exercised in patients with liver failure, moderate or severe renal insufficiency, and in elderly patients.

Taking Claritromicina Farmalider with Other Medications:

Inform your doctor or pharmacist if you are taking, have recently taken, or may take any other medications, including those purchased without a prescription.

Do not take clarithromycin with ergot alkaloids, astemizole, terfenadine, cisapride, domperidone, pimozide, ticagrelor, ranolazine, colchicine, certain medications for high cholesterol, and medications known to cause severe heart rhythm disturbances (see "Do not take Claritromicina Farmalider film-coated tablets").

This is especially important if you are taking medications for:

• Heart problems (e.g., digoxin, verapamil, quinidine, or disopyramide).
• Blood thinning (e.g., warfarin, dabigatran, rivaroxaban, apixaban, edoxaban).
• Migraine (e.g., ergotamine or dihydroergotamine).
• Epilepsy or bipolar disorder (carbamazepine, valproate, phenobarbital, or phenytoin).
• High cholesterol (e.g., simvastatin or lovastatin).

Or if you are taking any medication called:

• Theophylline (used in patients with breathing difficulties, such as asthma).
• Triazolam, alprazolam, or midazolam (sedatives).
• Cilostazol (for poor circulation).
• Methylprednisolone (a corticosteroid).
• Ibrutinib or vinblastine (for cancer treatment).
• Cyclosporine (immunosuppressant).
• Rifabutin (for the treatment of certain infections).
• Tacrolimus or sirolimus (for organ transplants and severe eczema).
• Sildenafil, tadalafil, or vardenafil (for treating impotence in adult men or for pulmonary arterial hypertension).
• Zidovudine (for treating viruses).
• St. John's Wort (a herbal product for treating depression).
• Phenobarbital (a medication for treating epilepsy).
• Nevirapine and efavirenz (antiviral medications used in the treatment of HIV infection for AIDS treatment) may decrease clarithromycin levels.
• Rifampicin or rifapentine (for treating tuberculosis).
• Omeprazole (for treating stomach acid and stomach or intestinal ulcers).
• Ritonavir (an antiviral medication used in the treatment of HIV infection) may increase clarithromycin levels. The concomitant use of atazanavir, etravirine, and saquinavir (also antiviral medications used in the treatment of HIV infection) with clarithromycin may increase both atazanavir (or saquinavir) and clarithromycin levels.
• Itraconazole (an antifungal) taken with clarithromycin may increase the levels of both medications.
• Fluconazole, another antifungal medication, may increase clarithromycin levels.
• Tolterodine (for treating symptoms of overactive bladder). In some patients, tolterodine levels may increase when taken with clarithromycin.
• Quetiapine (for schizophrenia or other psychiatric conditions).
• Beta-lactam antibiotics (certain penicillins and cephalosporins).
• Aminoglycosides (used as antibiotics to treat infections).
• Calcium channel blockers (medications for treating high blood pressure).
• Hydroxychloroquine or chloroquine (used to treat diseases such as rheumatoid arthritis or to treat or prevent malaria). Taking these medications at the same time as clarithromycin may increase the risk of abnormal heart rhythms and other severe adverse reactions affecting the heart.
• Corticosteroids, administered orally, by injection, or inhaled (used to suppress the immune system; this is useful in treating a wide variety of diseases).

Pregnancy, Breastfeeding, and Fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

The safety of clarithromycin during pregnancy has not been established, so your doctor will carefully weigh the benefits against the potential risks, especially during the first three months of pregnancy.

Claritromycin passes into breast milk, so breastfeeding should be interrupted during treatment with clarithromycin.

Driving and Using Machines

Since clarithromycin can cause dizziness, vertigo, confusion, and disorientation, you should exercise extreme caution when driving or using hazardous machinery during treatment with clarithromycin.

Claritromicina Farmalider Contains Sodium

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".

Specific Adverse Effects

Phlebitis at the injection site, pain at the injection site, pain at the venipuncture site, and inflammation at the injection site are specific to the intravenous formulation of clarithromycin.

After the marketing of the medicine, reports of effects on the central nervous system (e.g., somnolence and confusion) have been received with the simultaneous use of clarithromycin and triazolam. It is suggested to monitor the patient.

In some reports of rhabdomyolysis, clarithromycin was administered concomitantly with statins, fibrates, colchicine, or allopurinol (see Do not take Clarithromycin Farmalider and see Warnings and Precautions).

There have been rare reports that prolonged-release clarithromycin tablets appear in the feces; many of these cases have occurred in patients with gastrointestinal anatomical disorders [including ileostomy or colostomy (surgery to expel intestinal waste artificially from the ileum or colon)] or functional disorders (caused by a defect in the body) with shortened gastrointestinal transit time. In several reports, tablet residues have appeared in the context of diarrhea. It is recommended that patients who present with tablet residues in the feces and who do not experience any improvement change to another formulation of clarithromycin (e.g., suspension) or to another antibiotic.

Adverse Effects in Children and Adolescents

It is expected that the frequency, type, and severity of adverse reactions in children will be the same as in adults.

Immunocompromised Patients

In patients with AIDS and in other patients with a damaged immune system, treated with the highest doses of clarithromycin for long periods of time for mycobacterial infections, it is often difficult to distinguish adverse effects possibly associated with the administration of clarithromycin from those caused by the disease or by other diseases that the patient may have along with AIDS.

In adult patients treated with total daily doses of 1,000 mg and 2,000 mg of clarithromycin, the most frequent adverse reactions that appeared were: nausea, vomiting, alteration of taste, abdominal pain, diarrhea, skin rash, flatulence, headache, constipation, hearing disturbances, and elevations in transaminases (which may indicate liver, pancreas, heart, or muscle damage). Less frequently, difficulty breathing, insomnia, and dry mouth appeared. The incidences were similar in patients treated with 1,000 mg and 2,000 mg, but in general, they were 3 to 4 times more frequent in those who received a total daily dose of 4,000 mg of clarithromycin.

In these patients with a damaged immune system, around 2% to 3% who received 1,000 mg or 2,000 mg of clarithromycin daily presented severely abnormal elevated transaminase levels, as well as abnormally low white blood cell and platelet counts. A smaller percentage of patients in both dosage groups had increased blood levels of urea (which may indicate decreased renal function). In patients who received 4,000 mg daily, slightly higher incidences of abnormal values were observed in all parameters, except for the white blood cell count.

Contact a doctor as soon as possible if you experience a severe skin reaction: a red and scaly rash with bumps under the skin and blisters (pustular exanthematous). The frequency of this adverse effect is considered unknown (cannot be estimated from the available data).
