carbidopa / levodopa / entacapone

Generic Stalevo
Used for Parkinson's Disease

Stalevo is a combination medication that treats Parkinson's disease (PD) in adults. It contains carbidopa and levodopa, which help raise dopamine levels in the brain to improve PD symptoms. It also has entacapone, which works as a COMT inhibitor to help the effects last longer. Stalevo helps lessen "off" time (when movement symptoms come back as the medication wears off). Side effects include involuntary movements, nausea, and diarrhea.

What is Stalevo?

What is Stalevo used for?

How Stalevo works

Stalevo is a combination of three ingredients: carbidopa, levodopa, and entacapone. These ingredients work together to bring up the dopamine levels in the brain. This helps relieve symptoms of Parkinson's disease (PD).

  • Levodopa is a dopamine replacement. Levodopa travels into the brain where it turns into dopamine. When there's more dopamine in the brain, PD symptoms lessen.
  • Carbidopa is a dopa decarboxylase inhibitor, and entacapone is a catechol-O-methyltransferase (COMT) inhibitor. Dopa decarboxylase and COMT are proteins in the body that break down levodopa before it reaches the brain. By blocking these proteins, more levodopa can get to the brain and turn into dopamine. It helps both levodopa and dopamine reach and stay at higher levels in the brain. This helps relieve PD symptoms.

Pharmacist tips for Stalevo

pharmacist
  • Take Stalevo with or without food. Avoid taking the medication with a high-fat, high-calorie, or high-protein meal. Examples include avocados, cheese, and peanut butter. These foods can slow the medication from getting absorbed into the body by about 2 hours.
  • Only take 1 Stalevo tablet when it's time for you to take the medication. All tablet strengths of Stalevo contain 200 mg of entacapone. Taking more than 1 Stalevo tablet at once can raise your risk of side effects.
  • Swallow the Stalevo tablet whole. Don't cut, crush, or chew them. If you have trouble swallowing pills whole, tell your prescriber so they can find other options for you.
  • Stalevo can make you very sleepy and even cause you to fall asleep suddenly, even if you don't feel tired. Don't drive or do anything that needs your focus until you know how the medication affects you.
  • Stalevo can cause or worsen uncontrolled movements of your body. These involuntary movements are called dyskinesia. It happen sooner and at lower dosages than with carbidopa/levodopa-only medications (like Sinemet). Let your prescriber know if you have uncontrolled movements that bother you a lot.
  • Stalevo can cause nausea, vomiting, or diarrhea in some people. Make sure to drink plenty of fluids to prevent dehydration if you have these side effects during treatment. Talk to a healthcare professional if they don't get better. They can check whether there's something else going on.
  • Let your care team know if you feel numbness, tingling, or confusion while taking Stalevo. Also tell them if you notice your tongue is getting sore or red, or if you see unusual cracks at the corners of your mouth. These might be signs of low vitamin B6, which could happen with this medication. Your care team can check your levels with a blood test and suggest a vitamin B6 supplement if needed.
  • Stalevo can change the color of your saliva, sweat, and urine. These bodily fluids can look darker, even red, brown, or black. It might look strange or scary, but it's harmless. Just be careful with your clothing because it can stain.
  • Ask your prescriber or pharmacist before taking iron supplements or multivitamins with iron. Iron can cause less Stalevo to get absorbed into your body. This can make Stalevo work less well to relieve your PD symptoms.

Risks and warnings for Stalevo

Stalevo can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Sleepiness or falling asleep during activities

  • Risk factors: History of drowsiness | History of sleep problems | Taking sedatives or medications that make you drowsy

Some people taking Stalevo have fallen asleep out of nowhere. This has happened even when they didn't feel tired beforehand. It can happen during activities like talking or eating. In some cases, people have fallen asleep while driving. It's sometimes led to accidents.

Avoid driving or doing things that need your full attention until you know how Stalevo affects you. This is especially important if you often feel sleepy or have suddenly fallen asleep before. Also avoid taking medications that make you sleepy while taking Stalevo. They can make you even sleepier.

Tell your prescriber know if you feel very sleepy during the daytime while taking Stalevo. Also let them know if you fall asleep during activities that you need to be alert for. Your prescriber can help decide if it's safe for you to keep taking the medication.

Low blood pressure and fainting

  • Risk factors: History of low blood pressure

Some people who take Stalevo can have low blood pressure. It can cause a drop in blood pressure when you stand from a sitting or lying down position. Low blood pressure can lead to dizziness, lightheadedness, and sometimes fainting.

To lower your risk of falling, get up slowly when you stand. Tell your prescriber if your blood pressure is lower than usual or if you feel dizzy while taking Stalevo.

Risk of depression and suicidal behavior

  • Risk factors: History of mental health conditions

Stalevo can cause depression with or without suicidal behavior. Get medical help right away if you or the people around you notice that you have signs of depression or thoughts of hurting yourself while taking this medication.

Hallucinations and changes in behavior and thoughts

Some people taking medications like Stalevo have had hallucinations. Others can also have feelings of uneasiness or distress. Tell your prescriber if you or your loved ones notice you're having hallucinations while you're taking Stalevo. Also let them know about any unusual behaviors or unusual thoughts.

Difficulty controlling impulsive behavior

Parkinson's medications that raise dopamine levels, like Stalevo, can cause impulsive behavior. These behaviors can include strong sexual urges and gambling urges. They can also be urges to spend a lot of money and binge eating. Urges can be hard to control.

Tell your prescriber if these behaviors negatively affect your life while taking Stalevo. You might not notice these urges. So, your prescriber might ask about them at your next visit.

High fevers and confusion with treatment changes

Although rare, starting Stalevo, suddenly lowering the dose suddenly, or stopping it too fast can cause high fever and confusion. It can be life-threatening if these symptoms happen along with muscle stiffness, irregular pulse, rapid breathing, or changes in blood pressure.

Don't stop taking Stalevo or lower your dose without talking to your prescriber first. They can tell you how to do this safely.

Diarrhea and inflamed colon (colitis)

The entacapone in Stalevo can cause people to have diarrhea. In studies, some had mild or moderate diarrhea. Rarely, people had severe diarrhea. People started to have diarrhea in the first few months of treatment. But it can sometimes start as early as the first week.

Keep in mind that diarrhea can be a sign of inflammation in the colon (colitis). Diarrhea in this case can be moderate or severe with watery, non-bloody stool. You might also have stomach pain.

Sometimes, diarrhea and colitis can lead to weight loss, dehydration, and low potassium levels. Be sure to drink lots of fluids to stay hydrated.

Tell your care team if you have any diarrhea or other related symptoms while taking Stalevo. Most of the time, diarrhea and colitis get better or go away after stopping the medication.

Severe muscle damage (rhabdomyolysis)

Some people who took Stalevo had severe muscle damage called rhabdomyolysis, which can be serious. Tell your prescriber right away if you have muscle aches, soreness, cramping, or a fever while you're taking Stalevo. These can be signs of serious muscle damage.

Low vitamin B6 levels and seizures

  • Risk factors: Taking a high dose of Stalevo

Taking medications with carbidopa and levodopa, like Stalevo, can lower your vitamin B6 levels. The risk of vitamin B6 deficiency is greater if you're taking a higher dose of the medication.

Low vitamin B6 can cause a rash, a swollen tongue, or numbness and tingling in your hands and feet. In serious cases, it can lead to depression, confusion, or even seizures. These seizures might not get better with usual anti-seizure medications. And they might only improve when given extra vitamin B6.

Your care team will check your vitamin levels with blood tests before you start Stalevo. They'll also check again periodically during treatment. Tell your care team if you notice symptoms of low vitamin B6. These include a sore tongue, cracked corners of your mouth, or numbness and tingling. Your care team might suggest a vitamin B6 supplement to keep your levels up.

Interactions with other medications

Stalevo can interact with a few medications and cause side effects. Examples include apomorphine (Apokyn), methyldopa, and epinephrine (EpiPen). Taking Stalevo with these medications can raise your heart rate and blood pressure. It can cause changes to your heart rhythm.

It's also harmful to take Stalevo with nonselective monoamine oxidase inhibitors (MAOIs). Don't take Stalevo with nonselective MAOIs, like phenelzine (Nardil) and tranylcypromine (Parnate). Note that some Parkinson's medications like rasagiline (Azilect) and selegiline are selective MAO-B inhibitors. It's okay to take these Parkinson's medications with Stalevo.

Share a list of all your medications with your care team. They can check for interactions and make sure you're safe.

Risk of stomach bleeding in people who've had a stomach ulcer

Let your prescriber know if you've had a stomach ulcer before. This is because Stalevo might raise your risk of stomach bleeding. Get medical help right away if you have severe stomach pain, vomit or cough up blood, or notice black stools that look like tar. These can be signs of stomach bleeding.
