Consumer Information

This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.

What the medication is used for

NOVAHISTEX DH is a prescription medicine, for adults and for children 12 and over, used to treat cough associated with colds that is not responding to other medications.

What it does

NOVAHISTEX DH contains two ingredients, hydrocodone bitartrate and phenylephrine HCl.

Hydrocodone bitartrate helps suppress cough by acting on the cough center in the brain. Phenylephrine HCl works by constricting blood vessels in the nasal passages, helping to relieve nasal congestion.

Warnings and precautions

Serious Warnings and Precautions

  • Even if you take NOVAHISTEX DH as prescribed you are at a risk for opioid addiction, abuse and misuse. This can lead to overdose and death.

  • You may get life-threatening breathing problems while taking NOVAHISTEX DH. This is less likely to happen if you take it as prescribed by your doctor. Babies are at risk of life-threatening breathing problems if their mothers take opioids while pregnant or nursing.

  • You should never give anyone your NOVAHISTEX DH. If a person has not been prescribed NOVAHISTEX DH, they could die from taking it. This is especially true for children.

  • If you took NOVAHISTEX DH while you were pregnant, whether for short or long periods of time or in small or large doses, your baby can suffer life-threatening withdrawal symptoms after birth. This can occur in the days after birth and for up to 4 weeks after delivery. If your baby has any of the following symptoms:
    • has changes in their breathing (such as weak, difficult or fast breathing)
    • is unusually difficult to comfort
    • has tremors (shakiness)
    • has increased stools, sneezing, yawning, vomiting, or fever
    Seek immediate medical help for your baby.

  • Taking NOVAHISTEX DH with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take NOVAHISTEX DH. Talk about any health conditions or problems you may have, including if you:

  • have a history of illicit or prescription drug or alcohol abuse
  • have severe kidney, liver or lung disease
  • have diabetes
  • have glaucoma
  • have heart problems or peripheral vascular disease (problems with your blood vessels)
  • have low blood pressure
  • have high blood pressure
  • have past or current depression
  • suffer from chronic or severe constipation
  • have problems with your thyroid, adrenal or prostate gland
  • have, or had in the past hallucinations or other severe mental problems
  • suffer from migraines
  • are pregnant or planning to become pregnant

Other warnings you should know about:

Use in Children

Young children are at greater risk of the sedating effects of narcotic cough drugs. The use of hydrocodone in young children has led to slow, shallow or weak breathing that has been fatal. NOVAHISTEX DH should be given with caution to children. This is especially true for children who have difficulty breathing. NOVAHISTEX DH is not recommended for children under 12.

Opioid dependence and addiction:
As with all opioids, taking NOVAHISTEX DH may cause you to become dependent on it. Do not take more than the dose prescribed to you by your doctor. There are important differences between physical dependence and addiction. It is important that you talk to your doctor if you have questions or concerns about abuse, addiction or physical dependence.

Pregnancy, nursing, labour and delivery:
Opioids can be transferred to your baby through breast milk, or while still in the womb. NOVAHISTEX DH can then cause life-threatening breathing problems in your unborn baby or nursing infant. Your doctor will determine if the benefits of using NOVAHISTEX DH outweigh the risks to your unborn baby or nursing infant.

If you are pregnant and are taking NOVAHISTEX DH, it is important that you don’t stop taking your medication all of a sudden. If you do, it can cause a miscarriage or a still-birth. Your doctor will monitor and guide you on how to slowly stop taking NOVAHISTEX DH. This may help avoid serious harm to your unborn baby.

Driving and using machines: Before you do tasks which may require special attention, you should wait until you know how you react to NOVAHISTEX DH. NOVAHISTEX DH can cause:

  • drowsiness
  • dizziness or
  • lightheadedness

This can usually occur after you take your first dose and when your dose is increased.

Serotonin Syndrome: NOVAHISTEX DH can cause Serotonin Syndrome, a rare but potentially life-threatening condition. It can cause serious changes in how your brain, muscles and digestive system work. You may develop Serotonin Syndrome if you take NOVAHISTEX DH with certain antidepressants or migraine medications.

Serotonin Syndrome symptoms include:

  • fever, sweating, shivering, diarrhea, nausea, vomiting;
  • muscle shakes, jerks, twitches or stiffness, overactive reflexes, loss of coordination;
  • fast heartbeat, changes in blood pressure;
  • confusion, agitation, restlessness, hallucinations, mood changes, unconsciousness, and coma.

Disorder of the adrenal gland: You may develop a disorder of the adrenal gland called adrenal insufficiency. This means that your adrenal gland is not making enough of certain hormones. You may experience symptoms such as:

  • nausea, vomiting
  • feeling tired, weak or dizzy
  • decreased appetite

You may be more likely to have problems with your adrenal gland if you have been taking opioids for longer than one month. Your doctor may do tests, give you another medication, and slowly take you off NOVAHISTEX DH.

Sexual Function/Reproduction: Long term use of opioids may lead to a decrease in sex hormone levels. It may also lead to low libido (desire to have sex), erectile dysfunction or being infertile.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
