Sunosi – Solriamfetol uses, dose and side effects


75 mg 150 mg film-coated tablets

What Sunosi is and what it is used for

Sunosi contains the active substance solriamfetol. Solriamfetol increases the amount of the natural substances dopamine and norepinephrine in the brain. Sunosi helps you stay awake and less sleepy.

It is used

  • to adults with narcolepsy, a condition that makes you feel very sleepy at any time, suddenly and unexpectedly. Some patients with narcolepsy also have symptoms of cataplexy (when the muscles become weaker in connection with emotions such as anger, fear, laughter, or surprise. which Can sometimes lead to collapse).
  • to increase alertness and reduce excessive daytime sleepiness (EDS) in adult patients with obstructive sleep apnea (OSA) whose EDS has not been adequately treated with primary OSA treatment, such as continuous positive airway pressure (CPAP).

What you need to know before you take Sunosi

Do not take Sunosi if you

  • are allergic to solriamfetol or any of the other ingredients of this medicine (listed in section 6)
  • have had a heart attack in the past year
  • have serious heart problems, e.g. new chest pain or chest pain that lasts longer or is more severe than usual, high blood pressure that cannot be controlled with medicine, severely irregular heartbeat, or other serious heart problems
  • are taking a type of medicine called a monoamine oxidase inhibitor ( MAO inhibitor ) for depression or Parkinson’s disease, or have taken MAO inhibitors in the last 14 days.

Warnings and precautions

Talk to your doctor or pharmacist before taking Sunosi if you have or have had

  • heart problems, heart attack, or stroke
  • high blood pressure
  • alcoholism or any drug or drug abuse or dependence
  • an eye disease called narrow-angle glaucoma.

Tell your doctor or pharmacist before starting treatment if any of the above applies to you. Sonos may make some of these problems worse. The doctor will do checks to see how the medicine affects you.

Sonos does not replace your usual OSA treatment, e.g. CPAP. You should continue that treatment while taking Sunosi.
