Giving pain medications to children

Friday, February 8th, 2008

PainkillersGiving your child medications, even over-the-counter medicines, should always be carefully monitored by your doctor.

The American Academy of Family Physicians offers these suggestions before you give any pain medication to your child:

  • If a person younger than age 18 has the flu or chickenpox, never give the person aspirin, which could lead to a rare but deadly condition called Reye’s Syndrome.
  • Acetaminophen (the active ingredient in Tylenol) is a generally safe painkiller for young children.
  • Be careful about giving ibuprofen to children who are allergic to aspirin, as they may also be allergic to ibuprofen.
  • Pain relievers may be dangerous for children with asthma, so don’t administer them without a doctor’s consent.
  • Be careful not to give your child too much of the same medication. Sometimes the same active ingredient can be found in more than one medication.

Pain Medication in Young Children: How Are We Doing?

Not very well, especially for children younger than 2 years.

Doctors are known to do a poor job of treating pain. How do we do in treating pain in preverbal and very young children? To answer this question, these authors performed a retrospective chart review of patients 6 months to 10 years old who presented to a pediatric emergency department between 1999 and 2000 with isolated long-bone fractures or second- or third-degree burns.

Patients were excluded if they had closed head injury, chest or abdominal trauma, or a history of developmental delay or other neurologic impairment; 180 children were enrolled. The use of analgesics was assessed in 2 age groups: very young (6 to 24 months) and school-aged (6 to 10 years) children. More very young children than school-aged children did not receive analgesic agents (64.6% vs. 47.6%). When analgesics were used, very young patients were less likely to receive opioids (16.7% vs. 44.0%, respectively) and more likely to receive over-the-counter products (18.8% vs. 8.3%, respectively). Injury patterns differed significantly in the 2 age groups: Second-degree burns were more common in the very young group, and displaced fractures were more common in the school-aged group. Among children with nondisplaced fractures and among those with third-degree burns, there was no difference in analgesic treatment between the very young and school-aged groups.

Pain Medications

Over-the-Counter Pain Relievers

Over-the-counter (OTC) pain relievers include:

  • Acetaminophen (Tylenol, Aspirin Free Excedrin)
  • Nonsteroidal anti-inflammatory drugs (NSAIDs; aspirin, Motrin, Aleve and Orudis KT)
  • Topical Corticosteroids (Cortaid and Cortizone)

Both acetaminophen and NSAIDs reduce fever and relieve pain caused by muscle aches and stiffness, but only NSAIDs can also reduce inflammation (swelling and irritation). Acetaminophen and NSAIDs also work differently. NSAIDs relieve pain by reducing the production of prostaglandins, which are hormone-like substances that cause pain. Acetaminophen works on the parts of the brain that receive the “pain messages.” NSAIDs are also available in a prescription strength that can be prescribed by your physician.

Topical pain relievers are also available without a doctor’s prescription. These products include creams, lotions, or sprays that are applied to the skin in order to relieve pain from sore muscles and arthritis. Some examples of topical pain relievers include Aspercreme, Ben-Gay, Icy Hot and Capzasin-P. Corticosteroid creams are also available.

Prescription Pain Relievers

Prescription pain relievers include:

  • Corticosteroids
  • Opioids
  • Antidepressants
  • Anticonvulsants (antiseizure medications)

What Are Corticosteroids?

Prescription corticosteroids provide relief for inflamed areas of the body by easing swelling, redness, itching and allergic reactions. Corticosteroids can be used to treat allergies, asthma and arthritis. When used to control pain they are generally given in the form of pills or injections. Examples include: Deltasone, Hydeltrasol and Solu-Medrol.

Prescription corticosteroids are strong medicines and may have serious side effects, including:

  • Weight gain
  • Upset stomach
  • Headache
  • Mood changes
  • Trouble sleeping
  • Weakened immune system

To minimize these potential side effects, corticosteroids are prescribed in the lowest dose possible for as short of a length of time as needed to relieve the pain. Efforts are underway to develop safer corticosteroids.

What Are Opioids?

Opioids are narcotic pain medications that contain natural, synthetic or semi-synthetic opiates. Opioids are often used for acute pain, such as short-term pain after surgery. Some examples of opioids include:

  • Morphine
  • Fentanyl
  • Oxycodone
  • Codeine

Opioids are effective for severe pain and do not cause bleeding in the stomach or other parts of the body as can other types of pain relievers. It is rare for people to become addicted to opioids if the drugs are used to treat pain for a short period of time.

Side effects of opioids may include:

  • Drowsiness
  • Nausea
  • Constipation
  • Itching
  • Breathing problems
  • Addiction

What Are Antidepressants?

Antidepressants are drugs that can treat pain and/or emotional conditions by adjusting levels of neurotransmitters (natural chemicals) in the brain. These medications can increase the availability of the body’s signals for well-being and relaxation, enabling pain control for people with chronic pain conditions that do not completely respond to usual treatments.

Chronic pain conditions treated by low-dose antidepressants include some types of headaches (like migraines) and menstrual pain. Some antidepressant medications include:

  • Selective Serotonin Reuptake Inhibitors (SSRIs) such as Celexa, Prozac, Paxil, and Zoloft
  • Tricyclic antidepressants such as Elavil, Norpramin Sinequan, Tofranil, and Pamelor
  • Selective Serotonin and Norepinephrine Reuptake Inhibitors (SSNRIs) such as Effexor and Cymbalta

These drugs require a steady dose of the medicine build up in the body over a period of time to work. The doses needed to treat pain are often lower than those needed to treat depression.

In general, antidepressants have fewer long-term side effects than frequent, ongoing use of other pain medicines. Generally, SSRIs and SSNRIs have fewer side effects than tricyclic antidepressants. The most common side effects with antidepressants include:

  • Blurry vision
  • Constipation
  • Difficulty urinating
  • Dry mouth
  • Fatigue
  • Nausea
  • Headache

What Are Anticonvulsants?

Anticonvulsants are drugs typically used to treat seizure disorders. Some of these medications are shown to be effective in treating pain as well. The exact way in which these medicines control pain is unclear but it is thought that they minimize the effects of nerves that cause pain. Some examples include Tegretol, Neurontin and Lyrica.

In general they are well tolerated. The most common side effects include:

  • Drowsiness
  • Dizziness
  • Fatigue
  • Nausea

Other Pain Treatments

Another means of topical pain relief comes in the form of a Lidoderm patch, which is a prescription medication.

If your pain is not relieved by the usual treatments, your doctor may refer you to a pain management specialist. Doctors who specialize in pain management may try other treatments such as certain types of physical therapy or other kinds of medicine. They may also recommend TENS, a procedure that uses patches placed on the skin to send signals that stop pain.

Patient-controlled analgesia (PCA) is a method of pain control that allows the patient to control the amount of pain medication administered. This is often used in the hospital to treat pain. By pushing a button on a computerized pump, the patient receives a pre-measured dose of pain medicine. The pump is connected to a small tube that allows medicine to be injected intravenously (into a vein), subcutaneously (just under the skin), or into the spinal area.

Taking an antidepressant? Do NOT stop suddenly!

Saturday, January 26th, 2008

AntidepressantsIf you want to stop taking an antidepressant, it’s important to speak with your doctor first, the American Academy of Family Physicians says. The doctor may recommend weaning your body off the medication gradually.

People who stop an antidepressant too quickly may trigger a host of symptoms that doctors call antidepressant discontinuation syndrome. Symptoms may include:

  • Anxiety.
  • Feelings of depression or sadness.
  • Moodiness and irritability.
  • Tiredness.
  • Headaches and dizziness.
  • Nausea and vomiting.
  • Diarrhea.

If an antidepressant is causing an unpleasant side effect, your doctor may opt to lower your dose or prescribe a different type of antidepressant altogether.

What are antidepressants?
Antidepressants are medicines used to help people who have depression. Most people with depression get better with treatment that includes these medicines.

How do antidepressants work?
Most antidepressants are believed to work by slowing the removal of certain chemicals from the brain. These chemicals are called neurotransmitters. Neurotransmitters are needed for normal brain function. Antidepressants help people with depression by making these natural chemicals more available to the brain.

How long will I have to take an antidepressant?
Antidepressants are typically taken for at least 4 to 6 months. In some cases, patients and their doctors may decide that antidepressants are needed for a longer time.

What are the different kinds of antidepressants?
Antidepressants are put into groups based on which chemicals in the brain they affect. There are many different kinds of antidepressants, including:

Selective serotonin reuptake inhibitors (SSRIs)

  • citalopram (brand name: Celexa)
  • escitalopram (brand name: Lexapro)
  • fluoxetine (brand name: Prozac)
  • paroxetine (brand names: Paxil, Pexeva)
  • sertraline (brand name: Zoloft)

[ Antidepressants on CanadianMedsWorld ]

These medicines tend to have fewer side effects than other antidepressants. Some of the side effects that can be caused by SSRIs include dry mouth, nausea, nervousness, insomnia, sexual problems and headache.

Tricyclics

  • amitriptyline (brand name: Elavil)
  • desipramine (brand name: Norpramin)
  • imipramine (brand name: Tofranil)
  • nortriptyline (brand name: Aventyl, Pamelor)

Common side effects caused by these medicines include dry mouth, blurred vision, constipation, difficulty urinating, worsening of glaucoma, impaired thinking and tiredness. These antidepressants can also affect a person’s blood pressure and heart rate.

Serotonin and norepinephrine reuptake inhibitors (SNRIs)

  • venlafaxine (brand name: Effexor)
  • duloxetine (brand name: Cymbalta)

Some common side effects caused by these medicines include nausea and loss of appetite, anxiety and nervousness, headache, insomnia and tiredness. Dry mouth, constipation, weight loss, sexual problems, increased heart rate and increased cholesterol levels can also occur.

Norepinephrine and dopamine reuptake inhibitors (NDRIs)

  • bupropion (brand name: Wellbutrin)

Some of the common side effects in people taking NDRIs include agitation, nausea, headache, loss of appetite and insomnia. It can also cause increase blood pressure in some people.

Combined reuptake inhibitors and receptor blockers

  • trazodone (brand name: Desyrel)
  • nefazodone (brand name: Serzone)
  • maprotiline
  • mirtazpine (brand name: Remeron)

Common side effects of these medicines are drowsiness, dry mouth, nausea and dizziness. If you have liver problems, you should not take nefazodone. If you have seizures, you should not take maprotiline.

Monamine oxidase inhibitors (MAOIs)

  • isocarboxazid (brand name: Marplan)
  • phenelzine (brand name: Nardil)
  • tranlcypromine (brand name: Parnate)

MAOIs are used less commonly than the other antidepressants. They can have serious side effects, including weakness, dizziness, headaches and trembling. Taking an MAOI antidepressant while you’re taking another antidepressant or certain over-the-counter medicines for colds and flu can cause a dangerous reaction. Your doctor will also tell you what foods and alcoholic beverages you should avoid while you are taking an MAOI. You should not take an MAOI unless you clearly understand what medications and foods to avoid. If you are taking an MAOI and your doctor wants you to start taking one of the other antidepressants, he or she will have you stop taking the MAOI for a while before you start the new medicine. This gives the MAOI time to clear out of your body.

Will antidepressants affect my other medicines?
Antidepressants can have an effect on many other medicines. If you’re going to take an antidepressant, tell your doctor about all the other medicines you take, including over-the-counter medicines and herbal health products (such as St. John’s wort). Ask your doctor and pharmacist if any of your regular medicines can cause problems when combined with an antidepressant.
