Learn more about some of the side effects Gocovri may cause.

Falling asleep during regular activities or during the day

Taking Gocovri may result in falling asleep during regular activities or during the day. This is because the drug can cause extreme sleepiness and fatigue (low energy).

While this side effect wasn’t common in studies, people taking Gocovri have reported falling asleep during activities including:

  • driving a motor vehicle (which has resulted in accidents)
  • eating a meal
  • having a conversation

Extreme sleepiness caused by Gocovri can occur without warning. In some cases, people reported feeling awake and alert immediately before falling asleep.

You may be at increased risk of this side effect when taking Gocovri if you:

  • have a sleep disorder or unpredictable sleep patterns
  • take other drugs that can make you feel sleepy
  • consume alcohol

What might help

Before prescribing Gocovri, your doctor will assess your risk of extreme sleepiness. If you have other risk factors for daytime sleepiness or falling asleep during activities, your doctor may decide Gocovri isn’t safe for you.

If you start having these side effects while taking Gocovri, tell your doctor. They will help you decide whether you should continue taking Gocovri or stop driving.

Hallucinations, paranoia, or delusions

Taking Gocovri may cause hallucinations, paranoia, or delusions as a side effect.

  • A hallucination is seeing or hearing something that’s not really there.
  • Paranoia is fear or distrust that’s not rational.
  • A delusion is a false belief.

These were among the most common side effects reported in studies of Gocovri. They’re more likely to occur when you first start taking Gocovri, as well as any time your dose is increased.

You may also have an increased risk of these side effects if you have an existing mental health condition, such as schizophrenia. Due to this risk, doctors usually won’t prescribe Gocovri if you have certain mental health conditions.

Hallucinations, which were the most common side effect in Gocovri studies, occurred more often in adults ages 65 years and above. In some cases, people stopped taking Gocovri due to hallucinations.

What might help

If you have hallucinations, paranoia, or delusions while taking Gocovri, call your doctor immediately. They can help treat your symptoms and determine whether it’s safe for you to continue taking Gocovri.

But if you think you’re having a medical emergency, immediately call 911 or seek emergency medical care.

Trouble managing impulses

You may have trouble managing your impulses as a side effect of Gocovri. Examples of unmanageable urges the drug may cause include:

  • binge eating
  • increased sexual urges
  • strong urges to spend money
  • unusual gaming urges

It’s not clear whether trouble managing impulses was reported as a side effect in Gocovri’s studies. But other drugs that work in a similar way to Gocovri have caused this side effect. And this side effect has been reported in people taking Gocovri since the drug was approved for use.

What might help

Contact your doctor right away if you notice trouble managing your impulses while taking Gocovri. In some cases, lowering the dose or stopping the drug ended these urges.

Because it may be hard for you to identify these behaviors as unusual or abnormal, it’s important for someone to know you’re taking Gocovri. This can be a loved one, caregiver, or family member who can help identify unusual behaviors if you have them.

Allergic reaction

Some people may have an allergic reaction to Gocovri. While allergic reactions weren’t reported in studies of Gocovri, they can still occur.

Symptoms of a mild allergic reaction can include:

A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include swelling under your skin, usually in your eyelids, lips, hands, or feet. They can also include swelling of your tongue, mouth, or throat, which can cause trouble breathing.

Call your doctor right away if you have an allergic reaction to Gocovri. But if you think you’re having a medical emergency, immediately call 911 or your local emergency number.
