KLACID 500 mg LYOPHILIZED POWDER FOR INFUSION SOLUTION

1. What Klacid 500 mg lyophilized powder for solution for infusion is and what it is used for

Klacid 500 mg lyophilized powder is an antibiotic belonging to a group of substances called macrolides. Antibiotics interrupt the growth of bacteria (germs) that cause infections.

Klacid 500 mg lyophilized powder is indicated when parenteral therapy is required for the treatment of infections caused by susceptible organisms in adults and adolescents (12 to 18 years) in the following conditions:

• Pharyngitis (infection of the pharynx that causes sore throat) or streptococcal tonsillitis (infection of the tonsils): only in cases where first-line treatment with beta-lactams is not possible or when Streptococcus pyogeneshas shown sensitivity to clarithromycin.

• Acute bacterial sinusitis (infection of the paranasal sinuses that are around the forehead, cheeks, and eyes) (adequately diagnosed).
• Community-acquired pneumonia (inflammation of the lungs caused by different germs and originating outside a hospital).
• Acute exacerbation of chronic bronchitis (worsening of prolonged or repetitive lung inflammation).
• Mild to moderate skin and soft tissue infections when beta-lactam antibiotics are not appropriate.

2. What you need to know before you use Klacid 500 mg lyophilized powder for solution for infusion

Do not use Klacid 500 mg lyophilized powder for solution for infusion

• If you are allergic to clarithromycin, other macrolide antibiotics such as erythromycin or azithromycin, or any of the other components of this medicine (listed in section 6).
• If you have a creatinine clearance of less than 30 ml/min.
• If you have an irregular heartbeat.
• If you have severe kidney or liver problems.
• If you are taking ergotamine or dihydroergotamine or use 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 serious heart rhythm disturbances. Consult your doctor for alternative medications.
• If you are taking ticagrelor (to prevent 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 serious heart rhythm disturbances.
• If you are undergoing treatment with midazolam oral (for anxiety or to help fall asleep)
• If you have abnormally low levels of potassium or magnesium in your blood (hypokalemia or hypomagnesemia).
• If you or a family member have a history of heart rhythm disorders (ventricular arrhythmia, including Torsade de Pointes) or electrocardiogram (ECG) abnormalities 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 risk of side effects. Consult your doctor for alternative medications.
• If you are taking colchicine (for gout)
• If you are taking a medication containing lomitapide

Warnings and precautions

Consult your doctor or pharmacist before starting to receive Klacid

• 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, and repaglinide, sulfonylureas, or insulin) and clarithromycin may lower blood sugar levels too much. Careful monitoring of blood sugar is recommended.
• If you are taking a medication called warfarin (blood thinner).
• 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 apply to you, consult your doctor before receiving clarithromycin.

Using Klacid 500 mg lyophilized powder for solution for infusion with other medications

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medications, including those obtained without a prescription.

Klacid should not be used with ergot alkaloids, astemizole, terfenadine, cisapride, domperidone, pimozide, ticagrelor, ranolazine, colchicine, certain medications for high cholesterol, and medications known to cause serious heart rhythm disturbances (see “Do not use Klacid”).

This is especially important if you are taking medications for:

• Heart problems (e.g., digoxin, verapamil, quinidine, or disopyramide).
• Blood thinning (e.g., warfarin or other anticoagulants such as 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 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 (herbal product for treating depression).
• Phenobarbital (medication for treating epilepsy).
• Nevirapine and efavirenz may decrease clarithromycin levels.
• Rifampicin or rifapentine (for treating tuberculosis).
• Omeprazole (for treating stomach acid and stomach or intestinal ulcers).
• Ritonavir (antiviral medication used in HIV treatment) may increase clarithromycin levels. The concomitant use of atazanavir, etravirine, and saquinavir (also antiviral medications used in HIV treatment) 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 overactive bladder symptoms). 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 for treating diseases such as rheumatoid arthritis or for treating or preventing malaria). Taking these medications at the same time as clarithromycin may increase the risk of abnormal heart rhythms and other serious 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 range 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 using 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.

Clarithromycin 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 be cautious when driving or using hazardous machinery during treatment with clarithromycin.

Klacid 500 mg lyophilized powder for solution for infusion contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per vial; it is essentially “sodium-free”

3. How to use Klacid 500 mg lyophilized powder for solution for infusion

Klacid 500 mg lyophilized powder is administered intravenously.

4. Possible Adverse Effects

Like all medicines, this medicine can cause adverse effects, although not all people suffer from them.

Adverse effects are classified as very frequent (may affect more than 1 in 10 patients), frequent (may affect up to 1 in 10 patients), infrequent (may affect up to 1 in 100 patients), and of unknown frequency (cannot be estimated from available data).

The frequent and very frequent adverse reactions related to treatment with clarithromycin, in both adults and children, are abdominal pain, diarrhea, nausea, vomiting, and alteration of taste. These adverse reactions are usually mild and coincide with the known safety profile of macrolide antibiotics (see below).

There were no significant differences in the incidence of these gastrointestinal adverse reactions during clinical trials between the patient population with or without pre-existing mycobacterial infections.

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) with the simultaneous use of clarithromycin and triazolam have been received. 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 Klacid 500 mg lyophilized for solution for infusionand 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 (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:

Clinical trials have been conducted with pediatric clarithromycin suspension in children from 6 months to 12 years of age. Therefore, children under 12 years of age should take the pediatric suspension of clarithromycin. There is insufficient data to recommend a dosing regimen for the intravenous formulation of clarithromycin in patients under 18 years of age.

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 the effects 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 involvement). 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% of those 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 urea nitrogen levels (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 (pustulosis). The frequency of this adverse effect is considered unknown (cannot be estimated from available data).

Reporting of Adverse Effects

If you experience any type of adverse effect, consult your doctor, pharmacist, or nurse, even if it is a possible adverse effect that does not appear in this prospectus. You can also report them directly through the Spanish Pharmacovigilance System for Human Use Medicines: https://www.notificaram.es. By reporting adverse effects, you can contribute to providing more information on the safety of this medicine.

INFORMATION FOR HEALTHCARE PROFESSIONALS:

Adults:

The recommended dose in adults and adolescents (from 12 to 18 years) is 1 g per day, divided into two equal doses, each infused after subsequent dilution with a suitable intravenous diluent, over a period of 60 minutes. To date, there are no data that justify the intravenous use of clarithromycin in children. Clarithromycin should not be administered by bolus injection or intramuscularly.

Elderly Patients:

Same dose as adults.

Dosage in Patients with Mycobacterial Infections:

Although there are currently no data related to the use of intravenous clarithromycin in immunocompromised patients, there are data on the use of oral clarithromycin in HIV-infected patients. In disseminated or localized infections (M. avium, M. intracellulare, M. chelonae, M. fortuitum, M. kansasii), the recommended treatment in adults is 1000 mg/day divided into two doses.

Intravenous treatment may be administered for 2-5 days in severely ill patients and should be switched to oral clarithromycin treatment as soon as possible when indicated by the doctor.

Renal Impairment:

In patients with renal impairment, who have a creatinine clearance of less than 30 ml/min, the dose of clarithromycin should be reduced to half of the recommended dose.

Hepatic Impairment:

Clarithromycin should not be administered to patients with severe hepatic impairment combined with renal impairment. (see section 4.3)

Pediatric Population:

There are insufficient data to recommend a dosing regimen for the intravenous clarithromycin formulation in patients under 18 years of age.

Instructions for Preparation/Handling

1. Prepare the initial clarithromycin solution (reconstituted solution) by adding 10 ml of sterile water for injectable preparations to the 500 mg vial. Gently swirl until completely dissolved without any visible residue of undissolved macroparticles (may take up to 5 minutes). Only sterile water for injectable preparations should be used, as other diluents may cause precipitation during reconstitution. Do not use diluents containing preservatives or inorganic salts.

Note: When the product is reconstituted as mentioned above, each ml of reconstituted solution contains 50 mg of clarithromycin.

The resulting solution contains an effective antimicrobial preservative. If stored at room temperature (25°C), the reconstituted product should be used within 24 hours, and if stored at 2-8°C, within 48 hours.

1. Prior to administration, the reconstituted solution (500 mg in 10 ml of water for injectable preparations) will be added to 250 ml of the following diluents:

. Sodium chloride 0.9%.

. Glucose 5%.

. Glucose 5% in sodium chloride 0.3%.

. Glucose 5% in sodium chloride 0.45%.

. Glucose 5% in Lactated Ringer's solution or
