1. What CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG is and what it is used for
CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG is a medicine containing clodronic acid, an active substance belonging to a group of drugs used to treat bone diseases, known as bisphosphonates.
CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG is used in women for the prevention and treatment of bone thinning (osteoporosis) after menopause (the period of permanent cessation of menstrual cycles).

2. What you need to know before using CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE

FG
Do not use CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG:

• If you are allergic to clodronic acid or to any of the other ingredients of this medicine (listed in section 6).
• If you are taking other bisphosphonates, medicines similar to CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG.
• If you are allergic to lidocaine or to other amide-type local anesthetics, such as: bupivacaine, mepivacaine, ropivacaine, levobupivacaine.
• If you suffer from a heart condition causing loss of consciousness (Adam-Stokes syndrome).
• If you suffer from a heart rhythm disorder (Wolff-Parkinson-White syndrome, atrial fibrillation, sinoatrial, atrioventricular or intraventricular block).
• If you have a weak heart unable to supply adequate blood flow to the body (acute heart failure).
• If you suffer from a condition of reduced blood volume (hypovolemia).

This medicine is for intramuscular use only (i.e., injected into a muscle) and must not be administered into a blood vessel (intravenously). Accidental injection into a vein increases the risk of serious adverse reactions due to high blood levels of the anesthetic lidocaine (see section 3. If you use more CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG than you should).

Warnings and precautions

Talk to your doctor or pharmacist before using CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG.

Before and during treatment, your doctor will ask you to undergo blood tests to monitor kidney and liver function (see section 4. Possible side effects). It is important that you drink adequate amounts of fluids during treatment with this medicine, especially if you have kidney problems (see section 3. How to use CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG).

In particular, inform your doctor:

• If you have high levels of calcium in your blood.
• If you suffer from kidney disease (renal insufficiency).
• If you are being treated with CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG for cancer or osteoporosis and are undergoing dental treatment or need dental surgery. You should also inform your dentist that you are being treated with CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG (see section 4. Possible side effects), as preventive dental care may be necessary.
• If you suffer from heart diseases (particularly heart rhythm disorders with slow heart rate and heart failure) or if you have had heart surgery.
• If you suffer from liver disease.
• If you or a family member suffer from a condition causing a marked increase in body temperature following administration of local anesthetics such as lidocaine (familial malignant hyperthermia).
• If during treatment you experience thigh, hip or groin pain or weakness, as this could be an early symptom of a possible femoral fracture (see section 4. Possible side effects).
• If you suffer from seizures (epilepsy). Your doctor will closely monitor you for any possible symptoms.
• If you suffer from respiratory or pulmonary disorders.
• If you suffer from a disease causing muscle weakness (myasthenia gravis).
• If you have porphyria (a rare inherited blood disorder affecting the skin and nervous system).

Children and adolescents

The safety and efficacy of this medicine in pediatric patients have not been established.

Other medicines and CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

This is particularly important if:

• You are taking other bisphosphonates, medicines used to treat bone diseases, as concomitant use of CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG with other bisphosphonates is contraindicated (see section 2. Do not use CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG).
• You are taking non-steroidal anti-inflammatory drugs (NSAIDs), medicines used to treat inflammation (particularly diclofenac), as kidney problems may occur.
• You are taking aminoglycosides, medicines used to treat infections, as blood calcium levels may decrease (hypocalcemia).
• You are taking estramustine, a medicine used to treat prostate cancer (a gland in men that produces seminal fluid), as blood levels of estramustine may increase.
• You are taking medicines used to treat heart disorders, including irregular heartbeat, such as beta-blockers (e.g., propranolol), calcium channel blockers (e.g., amiodarone), or sodium channel blockers, as lidocaine may remain in circulation longer.
• You are taking cimetidine, a medicine mainly used to treat gastritis and gastric ulcer (a lesion in the stomach wall); fluvoxamine (a medicine used for depression); antiviral medicines such as ritonavir; antibiotics such as macrolides (erythromycin) or other antibiotics like ciprofloxacin; antifungal medicines such as ketoconazole, itraconazole, as this may lead to increased blood levels of lidocaine.
• You are taking barbiturates such as phenobarbital; medicines used to treat epilepsy such as carbamazepine; phenytoin; primidone; oral contraceptives or hormone replacement therapy, as this may lead to reduced blood levels of lidocaine.
• You are being treated with digitalis, medicines used to treat heart rhythm disorders, as this may increase the risk of heart rhythm disturbances.
• You are taking medicines used to relax muscles during general anesthesia, such as suxamethonium.

The solution is incompatible with alkaline solutions or oxidizing solutions.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
If you experience any eye or vision disturbances during treatment, STOP taking the medicine and consult an ophthalmologist.
Inform your doctor immediately if you experience:

• pain or sores in the mouth or jaw and/or maxilla (two facial bones), as these may be early signs of serious problems (bone death of the jaw and/or maxilla), usually associated with tooth extraction and/or local infection (see section 2. Warnings and precautions).

The possible side effects listed below are categorized by frequency:
Common (may affect up to 1 in 10 people):

• decreased levels of calcium in the blood without symptoms (asymptomatic hypocalcemia),
• diarrhoea, nausea, vomiting (usually mild in intensity),
• increased levels of transaminases in the blood (a test to assess liver function), usually within normal limits.

Rare (may affect up to 1 in 1,000 people):

• decreased levels of calcium in the blood with symptoms (symptomatic hypocalcemia),
• increased levels of parathyroid hormone (a hormone that regulates calcium levels) in the blood, associated with reduced calcium levels,
• increased levels of alkaline phosphatase in the blood (a test to assess bone and liver condition),
• increased levels of transaminases in the blood (a test to assess liver function) more than twice the upper normal limit, without other abnormalities in liver function,
• allergic reactions manifesting as skin reactions,
• unusual femur fracture (long bone in the leg), particularly in patients receiving long-term treatment for osteoporosis. Contact your doctor if you experience pain or weakness in the thigh, hip, or groin, as this may be an early sign of a possible femur fracture.

Very rare (may affect up to 1 in 10,000 people):

• consult your doctor if you experience ear pain, ear discharge, and/or ear infection. These episodes could be signs of bone damage in the ear.

The following side effects may also occur, for which the frequency cannot be determined from the available data:
Effects related to the eyes

• inflammation of the conjunctiva, the membrane covering the eye and the inner surface of the eyelids (conjunctivitis);
• eye inflammation (episcleritis, scleritis, and uveitis).
• Episcleritis and scleritis have been reported with other drugs belonging to the same class as clodronic acid (a class adverse reaction of bisphosphonates).

Effects related to the lungs

• breathing difficulties in patients with aspirin-sensitive asthma (a medicine used to treat fever, pain, and inflammation);
• allergic reactions manifesting as respiratory problems.

Effects related to the kidneys and urinary tract

• kidney disease (renal failure), severe kidney damage. Rarely, and especially in association with NSAIDs (medicines used to treat inflammation and pain), renal failure has led to death (more frequently with concomitant use of diclofenac). See section 2. Other medicines and CLODRONATO DISODICO E LIDOCAINA CLORIDRATO FG.

Effects related to bones and muscles

• severe bone, joint, and muscle pain. The onset of symptoms varies from days to several months after starting treatment with CLODRONATO DISODICO E LIDOCAINA CLORIDRATO FG;
• pain or sores in the mouth or jaw and/or maxilla (two facial bones). These may be early signs of serious problems (bone tissue death of the jaw and/or maxilla), usually associated with tooth extraction and/or local infection (see section 2. Warnings and precautions). In most cases, this has occurred in cancer patients.

Effects related to the injection site

• tenderness at the injection site, particularly with prolonged treatment duration.

Side effects specific to lidocaine
Listed below are side effects associated with lidocaine. There are insufficient data to determine the frequency of the individual effects listed. Side effects are generally due to either allergic reactions or excessively high blood concentrations resulting from accidental intravascular injection and/or overdose.

Immune system disorders
Severe allergic reaction (anaphylactoid), swelling of the larynx leading to breathing difficulty (bronchospasm), and drop in blood pressure (cardiorespiratory collapse) due to anaphylactic shock.
Nervous system disorders
Symptoms of excitation or depression associated with dizziness, drowsiness, visual disturbances, tremors, followed by altered consciousness, seizures, coma, prolonged contraction of the jaw muscles leading to tight closure of the jaw and maxilla (trismus), altered sensation in limbs or other body parts (paraesthesia).
Psychiatric disorders
Anxiety, disorientation.
Cardiac disorders
Slowed heart rate (bradycardia), heart rhythm disturbances (arrhythmias), myocardial depression up to cardiac arrest.
Eye disorders
Pupil dilation (mydriasis), blurred vision, double vision (diplopia).
Gastrointestinal disorders
Nausea, vomiting.
Respiratory, thoracic and mediastinal disorders
Difficulty breathing (dyspnoea), reduced breathing rate (respiratory depression).
Vascular disorders
Low blood pressure (hypotension), high blood pressure (hypertension), interruption of normal blood circulation due to cardiac arrest and reduced blood flow (circulatory collapse).
Skin and subcutaneous tissue disorders
Sudden reddening of the skin (various types of skin rashes), itchy or non-itchy rash with wheals (urticaria), itching.
Ear and labyrinth disorders
Ringing in the ears (tinnitus), increased sensitivity to relatively low noises (hyperacusis).

200 mg + 40 mg every 14 days may be used as an alternative dosing regimen in patients already being treated with one 100 mg vial per week.
Administration of one vial of CLODRONATE DISODIUM AND LIDOCAINE HYDROCHLORIDE FG
200 mg + 40 mg every 28 days may be used as an alternative dosing regimen in patients already being treated with one 100 mg vial every two weeks.
The optimal duration of bisphosphonate treatment for osteoporosis has not been established. The need for continued treatment should be periodically reassessed for each individual patient based on potential benefits and risks, particularly after 5 years or more of use.
Special populations
Children
The safety and efficacy of the medicinal product in paediatric patients have not been established.
Elderly
There are no specific dosage recommendations for elderly patients. Clinical studies have included patients over 65 years of age and no age-specific adverse events have been reported in this group.
Patients with renal impairment
Clodronate is primarily eliminated via the renal route. Therefore, it should be used with caution in patients with renal impairment. The clodronate dosage should be reduced as follows:

Clodronate should be administered before hemodialysis, the dose should be reduced by 50% on dialysis-free days, and the treatment regimen should be limited to 5 days. It should be noted that peritoneal dialysis removes clodronate poorly from the circulation.
The solution is incompatible with alkaline solutions or oxidizing solutions.
