1. What Luminalum UNIA is and what it is used for

Luminalum UNIA contains the active substance phenobarbital, which exerts a depressant effect on the central nervous system. Depending on the dose, the medicine has a calming, hypnotic, and anticonvulsant action.
Indications:

• Epilepsy – partial and generalized tonic-clonic seizures.

2. Important information before taking Luminalum UNIA

When not to take Luminalum UNIA

• if the patient is allergic to phenobarbital or to other barbituric acid derivatives or to any of the other ingredients of this medicine (listed in section 6);
• if the patient has respiratory failure;
• if the patient has severe liver insufficiency;
• if the patient is in hepatic coma;
• if the patient has porphyria (a disease characterized by abnormal heme production — a component of hemoglobin);
• if the patient has alcoholic disease;
• if the patient has acute poisoning with central nervous system depressants;
• if the patient is breastfeeding.

Warnings and precautions
Luminalum UNIA should be used with caution:

• if the patient has bronchial asthma or other diseases causing breathlessness, airway constriction or respiratory failure, because phenobarbital may exacerbate symptoms of breathlessness;
• if the patient has depression with suicidal tendencies;
• if the patient abuses drugs;
• if the patient has cerebral circulatory disorders;
• if the patient has severe anemia;
• if the patient has hyperkinesis (increased motor activity);
• if the patient has hyperthyroidism;
• if the patient has acute or chronic pain (possibility of masking significant symptoms);
• if the patient has diabetes;
• if the patient has adrenal insufficiency;
• if the patient is debilitated, as during treatment agitation, depression, confusion, disorientation may occur (see section 4: Possible side effects);
• if the patient has impaired liver or kidney function. In such patients, the doctor may reduce the dose.

Life-threatening skin reactions (Stevens-Johnson syndrome,
toxic epidermal necrolysis, or DRESS syndrome) have been reported during treatment,
initially appearing as reddish spots or round rashes, often with blisters on the trunk. Additionally,
ulceration of the oral cavity, throat, nose, genital organs, and conjunctiva may occur (symptoms may also include red and swollen eyes).
These potentially life-threatening skin symptoms are often accompanied by flu-like symptoms.
Initially, a mild rash may progress to extensive blisters or skin peeling.
Therefore, skin reactions should be monitored during treatment. If a rash or other
skin reactions occur, treatment should be discontinued and medical advice sought immediately. The highest risk of occurrence is during the first weeks of treatment.
If the patient develops Stevens-Johnson syndrome, toxic epidermal necrolysis, or
DRESS syndrome after taking a medicine containing phenobarbital, this medicine must never be used again in this patient.
If the patient develops a rash or the above skin symptoms, discontinue
phenobarbital immediately and seek medical advice without delay, informing the doctor about the use of this
medicine.
In case of prolonged treatment in children, vitamin D prophylaxis should be initiated
(1200 to 2000 IU/day) or vitamin D .
Phenobarbital use may lead to psychological and physical dependence. Abrupt
discontinuation of this medicine may cause withdrawal symptoms (see section: Discontinuation of Luminalum UNIA).
Long-term use of phenobarbital may reduce its effectiveness.
In children and elderly patients (over 65 years of age), phenobarbital may cause paradoxical reactions (see section 4: Possible side effects).
Phenobarbital affects the results of laboratory tests (see section: Luminalum UNIA and other medicines).

Luminalum UNIA and other medicines
Inform your doctor or pharmacist about all medicines currently taken or recently taken, as well as any medicines planned for future use.
Luminalum UNIA reduces the effectiveness of the following medicines:

• doxycycline (an antibiotic used to treat bacterial infections);
• metronidazole (a medicine used to treat infections caused by certain bacteria and protozoa);
• theophylline (a medicine used to treat bronchial asthma);
• quinidine (a medicine used to treat heart rhythm disorders);
• corticosteroids (called steroids, used to treat, among others, rheumatic diseases);
• cyclosporine (a medicine used in organ transplant patients);
• paracetamol (a medicine used to relieve pain and reduce fever);
• phenylbutazone (a medicine used to treat, among others, ankylosing spondylitis and rheumatoid arthritis);
• griseofulvin (an antibiotic used to treat fungal infections);
• itraconazole (a medicine used to treat fungal infections);
• levothyroxine (a medicine used to treat hypothyroidism);
• oral anticoagulants (used to reduce blood clotting, e.g., warfarin);
• oral contraceptives containing estrogens (a change in contraceptive method may be necessary);
• tricyclic antidepressants (used to treat depression);
• digoxin (a medicine used to treat heart failure and heart rhythm disorders);
• haloperidol (a medicine used to treat psychiatric disorders, including schizophrenia).

Particular caution is required when using Luminalum UNIA together with any of the following medicines:

• phenothiazine and thioxanthene derivatives (medicines used to treat psychiatric disorders, including schizophrenia), as they increase the risk of seizures; therefore, the doctor should adjust the dose of phenobarbital;
• chlorpromazine (a psychotropic medicine used to treat schizophrenia), because Luminalum UNIA reduces its effectiveness;
• primidone (a medicine used to treat epilepsy), because it may enhance the sedative effect of phenobarbital or increase the likelihood of adverse effects (e.g., the type of epileptic seizure may change). When phenobarbital and primidone are used together, a reduction in the primidone dose may be necessary;
• carbamazepine or succinic acid derivatives (medicines used to treat epilepsy); the doctor should monitor blood levels of carbamazepine and succinic acid derivatives;
• valproic acid (a medicine used to treat epilepsy), because it enhances the effect of phenobarbital;
• phenytoin (a medicine used to treat epilepsy), because phenobarbital alters (increases or decreases) its blood concentration;
• hydantoin (a medicine used to treat epilepsy), because adverse effects may occur; therefore, the doctor should closely monitor its blood concentration;
• rifampicin (an antibiotic used to treat tuberculosis or certain other infections) — may reduce phenobarbital blood levels; therefore, the doctor should adjust phenobarbital doses;
• MAO inhibitors (medicines used to treat depression), because they prolong the effect of phenobarbital;
• calcium channel blockers (medicines used to treat hypertension), because phenobarbital may enhance their blood pressure-lowering effect;
• guanethidine (a medicine used to treat hypertension), because phenobarbital may worsen symptoms of orthostatic hypotension (dizziness or fainting when rising from sitting or lying positions);
• vitamin D, because phenobarbital reduces its blood concentration; therefore, in patients taking phenobarbital long-term, especially children, rickets prophylaxis should be initiated, and vitamin D supplementation (1200 to 2000 IU/day) or vitamin D is recommended;
• prolonged use of phenobarbital before administration of anesthetics (e.g., halothane, enflurane, methoxyflurane) may cause liver damage, and when methoxyflurane is used, there is an additional risk of kidney damage;
• maprotiline (a medicine used to treat depression) — when used in high doses, may reduce the antiepileptic effect of Luminalum UNIA;
• ketamine (a medicine used for preoperative anesthesia), especially when used in high doses, increases the risk of hypotension — significant drop in blood pressure and (or) respiratory depression — slowed and shallow breathing, apnea, and death due to asphyxiation;
• carbonic anhydrase inhibitors (medicines used to treat glaucoma, e.g., acetazolamide) may cause osteopenia (reduced bone mass). If symptoms of osteopenia occur, the doctor should discontinue carbonic anhydrase inhibitors and initiate appropriate treatment.

Phenobarbital enhances the effect of the following medicines:

• hypnotics;
• sedatives;
• opioid analgesics (strong painkillers, e.g., morphine);
• sedating antihistamines (medicines used to treat, among others, allergies);
• methotrexate (a medicine used to treat certain cancers and rheumatoid arthritis).

Alcohol enhances the central nervous system depressant effect of phenobarbital.
Phenobarbital affects the results of certain laboratory tests:

• may reduce absorption of Co-labeled cyanocobalamin;
• may reduce response to metyrapone (due to enhanced metyrapone metabolism);
• false-positive response to phentolamine may occur;
• blood bilirubin concentration may decrease (due to induction of glucuronyltransferase
• the enzyme responsible for bilirubin conjugation).

Luminalum UNIA and alcohol
Do not consume any alcoholic beverages while taking this medicine. Alcohol enhances the effect of Luminalum UNIA.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or plans to become pregnant, she should consult a doctor or pharmacist before taking this medicine.
Pregnancy
Phenobarbital taken during pregnancy may cause serious congenital malformations and may affect how the child develops. Congenital malformations reported in studies include cleft lip (split upper lip) and cleft palate (split in the roof of the mouth) and heart defects. Other congenital malformations have also been reported, such as developmental abnormalities of the penis (hypospadias), smaller than normal head size, facial abnormalities, and nail and finger defects. If a patient takes phenobarbital during pregnancy, there is a higher risk than in other women of giving birth to a child with congenital malformations requiring treatment. In the general population, the baseline risk of serious developmental defects is 2-3%. In women taking phenobarbital, this risk is approximately three times higher.
Infants born to mothers who used phenobarbital during pregnancy may also be at increased risk of being smaller than expected.
Neurodevelopmental disorders (developmental delays due to brain development disorders) have been reported in children exposed to phenobarbital during pregnancy. Research findings on the risk of neurodevelopmental disorders remain inconsistent.
Phenobarbital should not be used during pregnancy unless other medicines are ineffective.
In case of pregnancy, consult a doctor immediately. The doctor should discuss the possible effects of phenobarbital on the unborn child and carefully weigh the risks and benefits of treatment. Do not discontinue phenobarbital without discussing it with your doctor, as abrupt discontinuation may increase the risk of seizures, which could harm the patient and her unborn child.
If a woman took phenobarbital during the third trimester of pregnancy, the pregnancy should be monitored to detect potential newborn complications such as seizures, excessive crying, muscle weakness, and feeding difficulties.
Women of childbearing potential, contraception
Women of childbearing potential should use effective contraception during treatment with phenobarbital and for two months after treatment ends. Phenobarbital may affect the effectiveness of hormonal contraceptives, such as birth control pills, and reduce their efficacy in preventing pregnancy. Discuss with your doctor, who will advise on the most appropriate type of contraception to use during phenobarbital treatment.
If the patient is a woman of childbearing age and plans pregnancy, she should consult her doctor before stopping contraception and before becoming pregnant about switching to other suitable treatment methods to avoid exposing the unborn child to phenobarbital.
Phenobarbital used in the third trimester of pregnancy may cause physical dependence, withdrawal symptoms, and bleeding in the newborn.
Luminalum UNIA must not be used during breastfeeding, as the medicine passes into breast milk.
Driving and operating machinery
Luminalum UNIA may cause drowsiness and prolonged reaction time; therefore, during treatment, do not drive or operate machinery.
Luminalum UNIA contains monohydrate lactose and sodium
If the patient has previously been diagnosed with intolerance to certain sugars, the patient should consult a doctor before taking this medicine.
The medicine contains less than 1 mmol (23 mg) of sodium per tablet, meaning the medicine is considered "sodium-free".
