Stesolid Novum – Diazepam uses, dose and side effects


5 mg/ml solution for injection, emulsion

What Stesolid Novum is and what it is used for

Stesolid Novum belongs to a drug group called benzodiazepines . It works by enhancing the effect of a depressant substance ( GABA ) in the brain. As a result, it acts as a tension reliever, sedative, muscle relaxant, and antispasmodic.

Stesolid Novum injection liquid is used when a very quick effect of diazepam is desired, for example in epilepsy, convulsions, acute anxiety, and restlessness and as a sedative (calming) agent before, for example, examinations and operations.

The diazepam contained in Stesolid Novum may also be approved to treat other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you receive Stesolid Novum

You should not receive Stesolid Novum if you:

  • are allergic to diazepam or other benzodiazepines, peanuts or soy, or to any of the other ingredients of this medicine (listed in section 6).
  • have a disease called myasthenia gravis, which causes the muscles to weaken and tire quickly.
  • suffer from sleep apnea (a sleep disorder that involves abnormal pauses in breathing during sleep).
  • have serious liver disease.
  • have acute respiratory depression (slow and/or shallow breathing).

Warnings and precautions

Talk to your doctor or pharmacist before receiving Stesolid Novum if you:

  • have suffered from alcoholism or drug abuse
  • are older. Stesolid Novum can confuse and affect the muscles, which can lead to falls and fall injuries.
  • have breathing problems
  • suffering from depression
  • have suicidal thoughts
  • have epilepsy or have previously had seizures

Other important aspects

  • Mental side effects – contact your doctor if you experience side effects such as agitation, restlessness, aggressiveness, nightmares, or hallucinations. Such side effects occur more often in children or the elderly. See section 4 “Possible side effects”.
  • Memory loss – during treatment you may experience memory loss, which occurs more often during treatment with high doses of Stesolid. Symptoms often occur several hours after taking the drug, so make sure you can get an uninterrupted 7-8 hour period of sleep to reduce the risks.
  • Dependence – with treatment with this medicine there is a risk of dependence. The risk increases with dose and duration of treatment and also in patients who previously had alcohol and drug problems. You should therefore receive Stesolid Novum for as short a time as possible.
  • Tolerance – if after a few weeks you notice that the effect of the medicine is not as strong as at the beginning of the treatment, you should talk to your doctor.
  • Withdrawal – withdrawal symptoms such as a relapse in sleep problems and anxiety can occur even at normal doses during a short treatment period, and to reduce the risk of withdrawal symptoms, the treatment must be gradually tapered. See section 3, “If your treatment with Stesolid Novum is interrupted”.

Other medicines and Stesolid Novum

Tell your doctor or pharmacist if you are using, have recently used, or might be using other medicines.

If the following medicines are taken in combination with Stesolid Novum, they can affect your mental health, make you very drowsy and worsen your breathing and blood pressure:

  • antidepressants (eg fluvoxamine, fluoxetine )
  • antipsychotics such as clozapine (for treating mental health problems)
  • antihistamines (for treating allergies )
  • anesthetic
  • sedative (used for calming effect)
  • sleeping pills (for sleeping problems)
  • muscle relaxants (eg suxamethone, tubocurarine)
  • some strong painkillers such as morphine ( opioids )
  • phenobarbital (to treat epilepsy or mental disorders)

Simultaneous use of Stesolid Novum and opioid medicines (strong painkillers, medicines for the treatment of opioid dependence, and certain cough medicines) increases the risk of drowsiness, breathing difficulties ( respiratory depression ), coma, and can be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

If the doctor prescribes Stesolid Novum at the same time as opioid drugs, the dose and duration of treatment must be limited by the doctor.

Tell your doctor if you are taking any opioid medication and follow your doctor’s dosage recommendations carefully. It may be good to inform friends or relatives to be aware of the signs and symptoms described above. Contact a doctor if you experience any of these symptoms.

Stesolid Novum can affect or be affected by certain medicines that contain the following active substances:

  • disulfiram (for the treatment of alcohol dependence)
  • medicines against epilepsy such as phenytoin and carbamazepine
  • theophylline (for treating asthma and other breathing problems)
  • cimetidine, omeprazole, or esomeprazole (medicines that reduce stomach acid)
  • rifampicin ( antituberculosis antibiotic )
  • ciprofloxacin ( antibiotic against, among other things, urinary tract infection)
  • atazanavir, ritonavir, delavirdine, efavirenz, indinavir, nelfinavir or saquinavir (antiviral medicines)
  • fluconazole , itraconazole, ketoconazole or voriconazole (medicines for fungal infections)
  • isoniazid (for the treatment of tuberculosis )
  • oral contraceptives ( birth control pills ), as they can make diazepam leave the body more slowly and increase its effect. Breakthrough bleeding can occur during simultaneous treatment with diazepam and oral contraceptives, but the preventive effect remains.
  • corticosteroids (anti-inflammatory drugs)
  • levodopa (for the treatment of Parkinson’s disease )
  • valproic acid (for the treatment of epilepsy and mental disorders)
  • ketamine (an anesthetic)

Stesolid Novum with food, drink, and alcohol

Do not drink alcohol during treatment with Stesolid Novum. Alcohol can affect the effect of Stesolid Novum, which can lead to impaired breathing, unconsciousness, and failing heart function and blood circulation.

Grapefruit and grapefruit juice should be avoided when taking Stesolid Novum. Grapefruit can increase the effect of Stesolid Novum.

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 receiving this medicine.

If you receive Stesolid Novum late in pregnancy or during delivery, the baby may have a low body temperature, and suffer from muscle weakness and breathing difficulties. If the medicine is taken regularly during the latter part of the pregnancy, the child may develop abstinence.

Your doctor will decide whether the benefit of the treatment outweighs the risk to the unborn child and whether the medicine is suitable for you.

You should not receive Stesolid Novum if you are breastfeeding.

Driving ability and use of machinery

Stesolid Novum can make you feel sleepy and can affect your ability to concentrate. It can also affect the muscles. These side effects may persist for several days even after treatment with diazepam has ended. You should not drive a car or use tools or machines if you experience such side effects.

How to get Stesolid Novum

You should always receive this medicine as directed by your doctor. Consult a doctor if you are unsure.

Dosage instructions

Dose and treatment time are determined by the doctor, who adapts it individually for you.

Elderly patients

If you are older or frail, there is a greater risk that you are sensitive to the side effects of Stesolid Novum and the dose may therefore need to be reduced. Your doctor decides which dosage of Stesolid Novum is right for you and how often you should dose.

Impaired kidney function

Dose in normally does not need to be adjusted.

Impaired liver function

If you have liver cirrhosis or impaired liver function, the dose must be lowered.

If you have received too much Stesolid Novum

If you have received too large a dose, or if you think a child has swallowed the liquid, you should immediately contact the nearest doctor or hospital for an assessment of the risk and advice.

Signs of overdose include impaired coordination, sleep-like drowsiness, fatigue, confusion, slurred speech, muscle weakness, and low blood pressure. Severe overdose can lead to coma (unconsciousness that cannot be lifted), cardiac arrest, and severe breathing difficulties.

If your treatment with Stesolid Novum is interrupted

Treatment with Stesolid Novum can lead to psychological or physical dependence. When physical dependence has developed, sudden discontinuation of treatment can lead to withdrawal. The probability of withdrawal and its severity depends on the duration of treatment, dose, and degree of dependence.

Treatment with the medicine must not be interrupted without first consulting your doctor. The dose should be reduced gradually before the treatment is stopped completely. If treatment with Stesolid Novum is stopped suddenly, the risk of withdrawal increases.

In case of abstinence, you may experience the following withdrawal symptoms, among other things:

  • Headache, muscle pain, severe anxiety, tension, restlessness, palpitations, sweating, tremors, stomach problems, irritation, aggression, sensory disturbances, muscle spasms, general malaise, loss of appetite, insomnia, mental side effects such as severe confusion, irritability, and seizures.
  • Recurrence of sleep problems and anxiety; a transient syndrome in which the symptoms that led to the initiation of treatment with Stesolid Novum return in an intensified form. This can be accompanied by mood swings, anxiety, sleep disturbances, and nervousness.
  • If you have epilepsy or have previously had seizures and discontinue treatment with Stesolid Novum, there is a risk of convulsions or prolonged epileptic seizures. There is also a risk of seizures if you have alcohol or drug problems and suddenly stop treatment with Stesolid Novum.

If you have further questions about this medicine, contact your doctor or pharmacist.
