1. What is Cemidon B6 and what is it used for

Cemidon B6is a combination of two medicinal substances. It contains isoniazid, an antibiotic belonging to the group of antitubercular medications and vitamin B6.

Antibiotics are used to treat bacterial infections and do not work for viral infections such as the flu or a cold.

It is essential to follow the instructions regarding dosage, administration, and treatment duration as indicated by your doctor.

Do not store or reuse this medication. If you have leftover antibiotics after completing treatment, return them to the pharmacy for proper disposal. Do not dispose of medications through the drain or in the trash.

Cemidon B6is indicated for the treatment of tuberculosis and, exceptionally, for the treatment of atypical mycobacterial infections.

It is also used for the prevention of:

  • Acute asymptomatic infection identified by tuberculin test.
  • Individuals at risk of reactivating tuberculosis.
  • Contacts with a person with tuberculosis.

2. What you need to know before starting to take Cemidon B6

Do not take CemidonB6

  • If you are allergic to the active ingredients or any of the other components of this medication (listed in section 6).
  • If you have severe liver problems.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Cemidon B6.

Be especially careful:

  • If you have a history of seizures or neurological problems. Medications to prevent seizures should be administered if there is a risk.
  • If you have any liver function abnormalities. Your doctor will monitor your liver function weekly for the first month and then monthly while you are on treatment. If any damage appears, your doctor will suspend treatment.
  • If you have a problem with alcohol addiction.
  • If you have any kidney disease. Your doctor will prescribe the most suitable dose for you.

Other medications and CemidonB6

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication, including over-the-counter medications.

Particularly, inform your doctor or pharmacist if you are using any of the following medications:

  • Medications used to treat epilepsy (phenytoin, carbamazepine). Your doctor may adjust the dose of this medication.
  • Aluminum salts (medications for treating stomach acid). They should be taken more than 2 hours apart from each other.
  • Halogenated anesthetics (medications used in surgical interventions). It is recommended to stop taking Cemidon a week before the intervention and not to restart it until 15 days have passed.
  • Oral anticoagulants (medications used to prevent the formation of blood clots) such as acenocoumarol.
  • Glucocorticoids (such as prednisolone).
  • Ketoconazole (medication for treating fungal infections). Cemidon doses should be spaced at least 12 hours apart. Your doctor may adjust the dose of ketoconazole medication.
  • Antibiotics used to treat tuberculosis (pyrazinamide, rifampicin). Increased clinical and biological monitoring is required.

Taking CemidonB6with food, drinks, and alcohol

Isoniazid interacts with foods containing a substance called tyramine, found in foods such as cheese and red wine. Additionally, if taken with foods containing a substance called histamine (for example, tuna or other tropical fish), it can cause an exaggerated response with headache, sweating, palpitations, flushing, and decreased blood pressure. Therefore, your doctor will advise you not to consume foods containing tyramine or histamine during your treatment with Cemidon B6.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor or pharmacist before using this medication.

In the case of pregnancy, Cemidon B6should not be administered except when the potential benefits outweigh the possible risks associated with treatment. Your doctor will make this evaluation.

Women who are breastfeeding should consult their doctor before taking this medication, as isoniazid passes into breast milk.

Driving and operating machinery

The influence of Cemidon B6on the ability to drive and operate machinery is important, as it can cause blurred vision and/or dizziness.

Cemidon B650 mg/15 mg tablets contain wheat starch, lactose, and tartrazine.

This medication contains very low levels of gluten (from wheat starch). One tablet does not contain more than 0.006 mg (6 micrograms) of gluten.

If you are allergic to wheat (other than celiac disease), you should not take this medication.

This medication contains lactose. If your doctor has indicated that you have an intolerance to certain sugars, consult with them before taking this medication.

This medication may cause allergic reactions because it contains tartrazine. It can cause asthma, especially in patients allergic to acetylsalicylic acid.

3. How to Take Cemidon B6

Administration form

The medication should be administered in the morning with an empty stomach, at least 30 minutes before or 2 hours after meals.

The notch is only for breaking the tablet if it is difficult to swallow it whole.

Due to its size, Cemidon tablets are not suitable for the treatment of adults, children, or adolescents who cannot swallow tablets.

If you estimate that the action of Cemidon B6is too strong or too weak, inform your doctor or pharmacist.

If you take more CemidonB6than you should

If you have taken more Cemidon B6than you should, consult your doctor or pharmacist immediately or call the Toxicological Information Service, phone: (91) 562 04 20, indicating the medication and the amount ingested.

After an excessive intake of this medication, nausea, vomiting, dizziness, visual disturbances, or hallucinations, increased levels of acid in the body, appearance of acetone in urine, and high blood sugar levels may be expected. With higher doses, respiratory depression and central depression may occur, potentially leading to convulsions and deep coma.

If you forgot to take CemidonB6

Do not take a double dose to compensate for the missed doses.

If you interrupt the treatment with CemidonB6

Your doctor will indicate the duration of your treatment with Cemidon B6. Do not stop treatment before, even if you feel better. If you stop treatment too soon, the infection may reappear.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.
