Valium Interactions

Harmful interactions can occur when taking Valium with antipsychotics, sleep medications, SSRIs and more.

Valium (diazepam)is a benzodiazepine prescription drug most frequently recommended for people with anxiety, seizures, muscle spasms or alcohol withdrawal.

Benzodiazepine drugs areSchedule IVdrugs, according to the DEA, which means their potential for abuse and addiction is low.

Valiumacts on the central nervous system by slowing down electrical impulses in the brain. This results in a calming, soothing and quieting effect. Its tranquilizing effects are also known to assist with seizure prevention, muscle spasms like restless leg syndrome, and abnormal body movement. Additionally, it is sometimes used to help withalcohol withdrawal side effects. Valium makes the individual feel drowsy and can alter moods as well.

When taken as prescribed, Valium is a relatively safe drug with a risk of minor side effects. However, when one combines Valium with drugs or substances that affect the central nervous system, there is a significant increase in the risk of side effects,includingdrowsiness, memory loss and confusion, breathing problems, hallucinations, depression, rage reactions, overdose, coma and even death.

Valium Drug Interactions

The most common drug interactions associated with Valium are pharmacodynamic interactions. Here, the effects of one drug are additive to the effects of another. Since Valium is a central nervous system (CNS) depressant, other drugs that are CNS depressants will enhance this effect.

Several drug groupspose significant risk of adverse interactions when taken withValium.

Phenothiazines

Phenothiazines are a group of medications that can be used to treat nausea or symptoms of psychosis. Common examples include chlorpromazine, thioridazine, fluphenazine and prochlorperazine.When takenwith Valium, these drugs pose an extremely high risk of drowsiness, dizziness, falls and memory loss.

Antipsychotics

Antipsychotics are also known as neuroleptics or major tranquilizers, and they’re prescribed to manage psychosis symptoms of bipolar disorder, schizophrenia and schizoaffective disorder. Examples include haloperidol, aripiprazole, risperidone, paliperidone, olanzapine, clozapine, lurasidone, ziprasidone, quetiapine and paliperidone.

All antipsychotic medications are CNS depressants to a certain extent, with some causing more depressant effects than others. When combined with Valium, side effectscan includeloss of coordination, confusion, drowsiness and weakness.

Anxiolytics

Anxiolytics are prescribed to treat symptoms of anxiety. There are different groups of medications that can treat anxiety, including SSRIs and SNRIs. Other anxiety medications, like benzodiazepines, should not be mixed with Valium since Valium itself is a benzodiazepine. Examples include Ativan, Xanax, Librium and Klonopin. Combining these drugsmay result inextreme CNS depression.

Sleep Medications

Sleep medications can be prescribed or purchased over-the-counter (OTC). Prescription sleep aids include zolpidem, eszopiclone, Dayvigo, Belsomra and zaleplon. OTC sleep medications typically include either doxylamine or diphenhydramine.

Like other drug interactions, combining Valium with sleep medicationsincreasesthe risk of CNS depression. The only non-sedating sleep medication that is safe to combine with Valium is Ramelteon, by prescription only, and melatonin, available over the counter.

Narcotic Analgesics

Commonly called “narcotics”, this group of medicines includes opiates and opioids. They relieve acute and chronic severe pain by binding to opioid receptors. Drugs include morphine, hydrocodone, codeine, fentanyl, methadone, tramadol, oxycodone and oxymorphone.

It is extremely dangerous to take narcotic pain medications along with benzodiazepines like Valium. The FDA recently required additionalboxed warningsto warn the public of the increased risk of overdose and death when combining these two types of drugs.

Sedative Antihistamines

Antihistamines are typically used to manage allergic reactions and sometimes cases of itching. However, a side effect of some of these drugs is that theycan havesedative properties. Drugs include diphenhydramine (Benadryl), chlorpheniramine and hydroxyzine. Follow your doctor’s instructions for these drugs cautiously while taking Valium and watch for symptoms of drowsiness, loss of coordination, confusion and sedation.

Anticonvulsants

Anticonvulsants are used to treat or prevent seizures in people with seizure disorders. Valium itself can be used to treat seizures, so sometimes it will be prescribed in combination with these types of drugs, but Valium can often be used safely if managed by a healthcare professional. Examples of anticonvulsants include gabapentin, valproic acid, barbiturates, benzodiazepines, carbamazepine, oxcarbazepine, tiagabine, topiramate, phenytoin, fosphenytoin, primidone, ethosuximide and zonisamide.

If you are taking anticonvulsants, you should speak with your healthcare provider about the potential risks of drug interactions with Valium.

Monoamine Oxidase (MAO) Inhibitors

MAOIs are antidepressant drugs that elevate the levels of norepinephrine, serotonin and dopamine in the brain. Drugs include Parnate, Nardil, Marplan and Emsam. While MAOIs have an extremely high number of drug interactions, theydo not interactwith Valium. However, anyone taking MAOIs should use caution before changing their drug regimen.

Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs are commonly prescribed to treat anxiety and depression. Common examples include fluoxetine (Prozac), citalopram (Celexa), sertraline (Zoloft), paroxetine (Paxil) and escitalopram (Lexapro).

Most SSRIs haveno interactionswith Valium and can be used safely at the same time. However, fluoxetine can cause anincreased potencyof Valium when taken together. There is an increased risk of sedation, confusion and loss of coordination when taking Valium and fluoxetine together.

Serotonin Norepinephrine Reuptake Inhibitors (SNRIs)

There are two commonly prescribed SNRIs: venlafaxine (Effexor) and duloxetine (Cymbalta). SNRIs can be used to treat anxiety or depression and can also be used to treat certain types of nerve pain.

There areno known interactionsbetween SNRIs and Valium.

Noradrenergic and Specific Serotonergic Antidepressants (NaSSAs)

The only NaSSA available by prescription in the United States is mirtazapine (Remeron). Mirtazapine is indicated for the treatment of depression, but may also be used for anxiety in some people.

Mirtazapine causes a significant level of CNS depression, so itcan increasethe risk of drowsiness, loss of coordination, confusion and somnolence when taken with Valium.

Alcoholic Beverages

Alcoholic beverages should never be combined with benzodiazepines like Valium. Alcohol, like many other drugs on this list, is a CNS depressant. However, the risk of overdose issignificantly increasedwhen taking Valium and alcohol together.

Signs and symptoms of overdose mayinclude:

• Cold or clammy skin
• Confusion
• Low body temperature
• Trouble breathing or irregular breathing
• Slowed heart rate
• Slow responses
• Vomiting

Harmful interactions can occur when usingValiumand any of the drugs listed above. Additionally, combining these drugs with Valium presents a greater chance of developing a chemical dependence and addiction.
