Understanding Restless Legs Syndrome (RLS): Symptoms and Impact

Restless Legs Syndrome (RLS) is a neurological disorder characterized by an irresistible urge to move the legs, often accompanied by uncomfortable sensations. These symptoms typically worsen during periods of rest or inactivity, particularly in the evening or at night, significantly impacting sleep quality and overall well-being.

People with RLS describe the sensation as:

• Creepy-crawly
• Tingling
• Itching
• Pulling
• Aching

The discomfort is temporarily relieved by movement, but this relief is often short-lived, leading to disrupted sleep patterns and daytime fatigue. RLS can affect people of all ages, but it tends to be more common in middle-aged and older adults.

The Benadryl Dilemma: Can It Trigger RLS Symptoms?

Many individuals turn to over-the-counter medications like Benadryl (diphenhydramine) for relief from allergies or as a sleep aid. However, for those with RLS, this common antihistamine may exacerbate symptoms rather than provide relief.

Can Benadryl trigger Restless Legs Syndrome? The short answer is yes, it can. The National Institute of Neurological Disorders and Stroke warns that diphenhydramine, the active ingredient in Benadryl and many “PM” pain relievers, may aggravate RLS symptoms. This is particularly concerning as many people use these medications to help them sleep, potentially worsening their condition instead.

Why Does Benadryl Affect RLS?

The mechanism behind Benadryl’s effect on RLS is related to its impact on the brain’s dopamine system. Diphenhydramine blocks dopamine receptors, which can intensify RLS symptoms. This blockage interferes with the normal functioning of the dopamine system, which plays a crucial role in movement control and sensory processing.

Common Medications That May Worsen RLS Symptoms

Benadryl is not the only medication that can potentially trigger or worsen RLS symptoms. Several other drugs have been identified as possible culprits:

1. Antidepressants (particularly those that increase serotonin levels)
2. Antipsychotics
3. Anticonvulsants
4. Anti-nausea medications
5. Sedating antihistamines

Is it possible for prescription medications to affect RLS? Indeed, some prescription drugs can impact RLS symptoms. For instance, some patients report that discontinuing medications like aripiprazole (Abilify) or tramadol can initiate RLS symptoms. It’s crucial for individuals with RLS to discuss all medications, including over-the-counter drugs, with their healthcare provider to identify potential triggers.

Lifestyle Factors and RLS: Understanding the Triggers

While medications can play a significant role in triggering or exacerbating RLS symptoms, various lifestyle factors can also influence the condition’s severity. Understanding these triggers can help individuals manage their symptoms more effectively.

Stress and Anxiety

How does stress impact RLS? Stress and anxiety are significant triggers for RLS symptoms. The relationship between stress and RLS is complex, with stress potentially worsening symptoms and RLS-related sleep disturbances increasing stress levels, creating a vicious cycle. Stress reduction techniques such as deep breathing exercises, meditation, or yoga may help alleviate symptoms.

Nicotine and Alcohol Consumption

Both nicotine and alcohol can have detrimental effects on RLS symptoms. Smoking cessation and reducing alcohol intake, particularly close to bedtime, may lead to symptom improvement. While alcohol might help some people fall asleep faster, it often interferes with sleep quality and can exacerbate RLS symptoms.

Exercise and Physical Activity

Does exercise help or hinder RLS management? The relationship between exercise and RLS is nuanced. Moderate, regular exercise during the day can help ease restlessness at night. However, vigorous exercise, especially close to bedtime, may have the opposite effect in some individuals, potentially triggering or worsening symptoms.

Caffeine Intake

As a stimulant, caffeine can interfere with sleep if consumed too close to bedtime. For individuals with RLS, limiting caffeine intake, particularly in the afternoon and evening, may help reduce symptom severity.

Alternative Treatments for Restless Legs Syndrome

While medication management is often a key component of RLS treatment, several alternative approaches have shown promise in symptom relief:

The Soap Under the Sheet Method

One unconventional remedy that has gained attention is placing a bar of soap under the bottom sheet of the bed. While it may sound unusual, some individuals report significant symptom relief using this method. The mechanism behind this potential effect is not well understood, but it’s a low-risk option that some find effective.

Iron Supplementation

Can iron deficiency cause RLS? Iron deficiency has been linked to RLS in some cases. For individuals with low iron levels, supplementation under medical supervision may help alleviate symptoms. It’s important to consult a healthcare provider before starting any supplementation regimen.

Massage and Stretching

Regular leg massages and gentle stretching exercises, particularly before bedtime, may help reduce RLS symptoms. These techniques can improve circulation and relax muscles, potentially easing the uncomfortable sensations associated with RLS.

The Importance of Sleep Hygiene in Managing RLS

Maintaining good sleep hygiene is crucial for individuals with RLS. Establishing a consistent sleep schedule, creating a relaxing bedtime routine, and optimizing the sleep environment can all contribute to better symptom management.

Creating an Optimal Sleep Environment

How can the bedroom environment impact RLS symptoms? A cool, dark, and quiet bedroom can promote better sleep. Consider using blackout curtains, white noise machines, or earplugs to minimize disturbances. Comfortable bedding and pillows that support proper alignment can also help reduce discomfort.

Establishing a Consistent Sleep Schedule

Going to bed and waking up at the same time every day, even on weekends, can help regulate the body’s internal clock. This consistency may help reduce the frequency and severity of RLS symptoms over time.

When to Seek Medical Help for RLS

While mild cases of RLS can often be managed with lifestyle changes and over-the-counter treatments, certain situations warrant medical attention:

• Symptoms significantly interfere with sleep or daily activities
• RLS occurs frequently (more than twice a week)
• Symptoms worsen despite self-management efforts
• New symptoms develop after starting a new medication

A healthcare provider can offer a comprehensive evaluation, identify potential underlying causes, and recommend appropriate treatment options, which may include prescription medications specifically designed to manage RLS symptoms.

The Future of RLS Research and Treatment

As our understanding of Restless Legs Syndrome continues to evolve, researchers are exploring new avenues for treatment and management. Current areas of focus include:

Genetic Studies

Is RLS hereditary? While not all cases of RLS are inherited, there is evidence of a genetic component in some families. Ongoing genetic studies aim to identify specific genes associated with RLS, which could lead to more targeted treatments in the future.

Novel Pharmacological Approaches

Researchers are investigating new medications that target different aspects of RLS pathophysiology. These include drugs that modulate dopamine levels more precisely or address other neurotransmitter systems involved in RLS.

Non-Invasive Brain Stimulation

Can brain stimulation techniques help manage RLS? Preliminary studies on transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) show promise in alleviating RLS symptoms. These non-invasive techniques may offer new options for individuals who don’t respond well to conventional treatments.

As research progresses, individuals with RLS can look forward to potentially more effective and personalized treatment options. In the meantime, working closely with healthcare providers and staying informed about current management strategies can help mitigate the impact of RLS on daily life and overall well-being.

Will Benadryl Trigger Restless Legs Syndrome?

People who experience restless legs syndrome (RLS) will go to great lengths to avoid it if they can. They describe RLS as a creepy-crawly feeling that is relieved only by moving the legs. It can be quite unbearable. This uncomfortable condition can make it difficult to relax. When RLS or the related periodic limb movement disorder (PLMD) occurs overnight, sufferers and their bed partners have trouble getting a decent night’s sleep. Doctors can prescribe medications to treat RLS, but frequently they fail to warn patients about other drugs that could trigger restless legs syndrome. One reader made an independent discovery of such a drug.

What Drugs Might Trigger Restless Legs Syndrome?

Q. I never suffered before from restless legs syndrome, although it makes my daughter miserable. Last year, though, I had two episodes of RLS about a month apart. It took me a while to connect the dots, but eventually I recalled I had taken Benadryl both times right before bed to relieve hay fever symptoms. I haven’t touched the stuff since.

Does Benadryl Trigger Restless Legs Syndrome?

This is not the first time we have received such a question:

Q. The antihistamine diphenhydramine aggravates my restless legs syndrome (RLS). I have learned to avoid it and ‘PM’ pain relievers that include it.

Don’t assume your physician knows this. Several doctors I spoke with knew nothing about it. As far as I’m concerned, I’m allergic to these drugs, and that is what I tell the nurses when they ask.

A. There is little research about this link. Nevertheless, the National Institute of Neurological Disorders and Stroke advises that diphenhydramine (the antihistamine in Benadryl and “PM” pain relievers) may aggravate RLS symptoms. This is especially alarming because so many people take this over-the-counter medicine at bedtime to help them sleep. It may disrupt sleep instead for those who are susceptible to RLS.

Many other medications can also trigger these uncomfortable sensations. Antidepressants, antipsychotics and anticonvulsants can intensify this condition. Readers report that stopping some medicines, like aripiprazole (Abilify) or tramadol can also initiate symptoms.

Soap for Restless Legs Syndrome:

For those whose RLS does not appear to be set off by a medication they can avoid, we suggest soap under the bottom sheet. It sounds crazy, but some people who have tried this remedy to ward off nocturnal leg cramps have found that it also eases restless legs syndrome.

Barbara reported:

“I had suffered with RLS for years on and off. I’d go a few weeks or months without symptoms but it always came back and lasted days or weeks. When it returned, it was like torture. I definitely knew I wanted no part of a prescription drug for it, so I tried creams, herbal supplements etc. Nothing worked. A friend told me about the bar of soap under the sheet and I tried it. It has been several months and NO SYMPTOMS at all. I didn’t even unwrap it!!!”

8 Triggers That Make Restless Legs Worse

• Stress and anxiety. Rachel Salas, MD, an assistant professor of neurology at the Johns Hopkins University School of Medicine in Baltimore, says that stress and anxiety are big restless legs triggers. Stress reduction techniques like deep breathing or yoga may help.
• Nicotine. If you need another reason to stop smoking, calming your restless legs is a good one. Talk with your doctor if you think you need help quitting.
• Alcohol. Many people with RLS report that drinking can lead to more restless legs symptoms. Although alcohol can help people fall asleep quickly, it interferes with the quality of sleep and can make sleep apnea worse , says Alon Avidan, MD, MPH, an associate professor of neurology and director of the Sleep Disorders Clinic at UCLA. Try omitting alcohol to see whether your restless legs improve and whether you feel more rested in the morning.
• Vigorous exercise. Getting moderate exercise during the day can help ease restlessness at night. But vigorous exercise, especially close to bedtime, can have the opposite effect in some people.
• Medications. A number of medications can make RLS worse. In particular, anti-nausea drugs and sedating antihistamines (like Benadryl) block the brain’s dopamine receptors, causing restless legs symptoms. Antidepressants that increase serotonin and antipsychotic medications can also aggravate the condition. Let your doctor know if your restless legs symptoms worsen after you take a new medication. A change in dosage or to a different medication may do the trick.
• Caffeine. Because caffeine is a stimulant, it can interfere with sleep if it’s consumed too close to bedtime. It’s long been on the list of restless legs triggers, but Dr. Salas says recent research shows it may not be that big of a problem. In fact, she says, it may be beneficial in some people. Try cutting out coffee, tea, colas, sports drinks, and even chocolate to see if your symptoms improve or worsen.

Other Restless Legs Triggers

Other health conditions can also cause restless legs. This is what’s called secondary restless legs syndrome:

• Pregnancy. According to Dr. Avidan, about 20 percent of pregnant women report restless legs symptoms. This is more likely in the last three months of pregnancy, and iron deficiency is usually the culprit. If symptoms crop up when you’re expecting, your doctor will probably test the level of iron in your blood and prescribe iron supplements if it’s too low. The good news is that your restless legs symptoms will probably go away soon after you have your baby.
• Medical conditions. Restless legs symptoms are also seen in some people with kidney failure and diabetes. Treating these conditions will often calm the restless legs.

The Restless Legs Syndrome Foundation suggests using a sleep diary to pinpoint your personal triggers and gauge the severity of your symptoms. Always tell your doctor if your symptoms get noticeably worse.
