phenyltoloxamine - hydrocodone
How does this medication work? What will it do for me?
This medication contains two medicinal ingredients: hydrocodone and phenyltoloxamine. Hydrocodone belongs to the class of medications called antitussives (cough suppressants). Phenyltoloxamine belongs to the class of medications called antihistamines.
These two ingredients work together for the treatment of exhausting or non-productive cough that is associated with cold or with upper respiratory allergic conditions. Relief from the symptoms of coughing usually lasts between 8 to 12 hours. Hydrocodone is a narcotic medication. This medication is normally prescribed only after non-narcotic medications have been found ineffective.

HEALTH CANADA ADVISORY
August 24, 2020
Health Canada has issued new restrictions concerning the use of hydrocodone. To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
A previous advisory on hydrocodone was issued on February 18, 2019. To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
Abdominal (stomach) conditions: Hydrocodone and other narcotic medications may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have abdominal or stomach problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Accidental use: Accidental ingestion of hydrocodone by someone for whom it has not been prescribed can lead to a fatal overdose. Children are especially at risk. Keep this medication out of sight and reach of children.
Alcohol and other medications that cause drowsiness: People taking this medication should not combine it with alcohol and avoid combining it with other medications, such as narcotic pain relievers or sedatives, that cause drowsiness. Doing so can cause additional drowsiness and reduced breathing as well as other side effects, which can be dangerous and possibly even fatal.
Breathing: Hydrocodone can suppress breathing. If you are at risk for breathing difficulties – for example, if you have asthma – discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Constipation: This medication may cause constipation or worsen existing constipation. Eating a high-fibre diet and following good bowel habits will help to minimize this effect. If you develop constipation easily or you have chronic constipation, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Dependence and withdrawal: This medication contains hydrocodone and may be habit-forming. Physical dependence, psychological dependence, and abuse have occurred with the use of hydrocodone. People with a history of past or current substance use problems may be at greater risk of developing abuse or addiction while taking this medication. If you have been taking this medication for a while, it should be stopped gradually as directed by your doctor.
Drowsiness and reduced alertness: Because this medication may cause drowsiness, avoid driving or other tasks requiring alertness and physical coordination until you determine how this medication affects you.
Head injury: People with head injuries or increased pressure in the head may have a higher risk of experiencing side effects (breathing problems) or worsening of their condition while taking this medication. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood pressure: Hydrocodone can cause low blood pressure, resulting in symptoms such as weakness or dizziness, particularly when rising suddenly from a sitting or lying position. People who are prone to low blood pressure (e.g., those taking diuretics) should be cautious when using this medication.
Medical conditions: If you have high blood pressure, diabetes, overactive thyroid, glaucoma, heart disease, or blood vessel disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Sedation: The sedating effects of this medication will add to those of other sedating medications. Alcohol increases the risk of severe side effects from hydrocodone.
Avoid drinking alcohol or taking hypnotics/sedatives (e.g., barbiturates such as phenobarbital or benzodiazepines such as diazepam), tricyclic antidepressants (e.g., amitriptyline, desipramine), benzodiazepines, or other narcotic medications while you are on this medication. Doing so can cause additional drowsiness and reduced breathing as well as other side effects, which can be dangerous and possibly even fatal.
Serotonin syndrome: Severe reactions are possible when hydrocodone is combined with other medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors; medications used to treat depression. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, changes in mental state including delirium and agitation. Coma and death are possible.
If you are taking antidepressants, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. Hydrocodone crosses into the placenta, where it can affect the developing baby. Babies born to mothers who have been taking this medication regularly prior to delivery are likely to be physically dependent on the medication. Withdrawal signs include irritability and excessive crying, tremors, hyperactive reflexes, increased respiratory rate, increased stools, sneezing, yawning, vomiting, and fever.
Breast-feeding: It is not known if hydrocodone passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: This medication is not recommended for children less than 18 years of age. Children are at increased risk of experiencing serious side effects such as breathing problems.
