DESCRIPTION
Waklert 150 mg contains armodafinil a wake‑promoting medicine used to reduce excessive daytime sleepiness in adults with narcolepsy, obstructive sleep apnea (as residual sleepiness when primary therapy is used) and shift work sleep disorder. It is intended for use under medical supervision and is not a substitute for sleep or for treatment of the underlying cause of sleep disorders.
Mechanism of action
- Dopamine Transporter (DAT) Inhibition: Armodafinil is a weak but selective inhibitor of the dopamine transporter, which can reduce dopamine reuptake and thereby increase extracellular dopamine levels. This action may support improved alertness and concentration. Â
- Orexin activation: Armodafinil appears to enhance orexin (hypocretin) signalling in brain regions that promote wakefulness which helps maintain the sleep wake cycle. Â
- GABA regulation: It may reduce GABAergic (inhibitory) tone in certain brain areas, which can contribute to reduced sleep propensity and sustained wakefulness.
SIDE EFFECTS
Common and clinically relevant side effects (which may occur in some patients) include:
- Headache Â
- Nausea or gastrointestinal upset Â
- Insomnia or difficulty falling asleep Â
- Dry mouth Â
- Anxiety, nervousness, or restlessness Â
- Dizziness Â
- Increased heart rate or palpitations in some individuals
Less common but important:
- Mood changes, irritability, agitation or depressive symptoms in susceptible patients. Â
- Rare allergic or hypersensitivity reactions, including serious skin reactions (e.g., Stevens-Johnson syndrome) have been reported very rarely with wake‑promoting agents and require immediate attention.
Stop Taking It and Get Medical Advice If…
Stop the medicine and seek urgent medical care if you experience:
- Widespread rash, blistering, peeling skin, mouth sores, fever or any sign of severe skin reaction. Â
- Swelling of the face, lips, tongue, or throat or difficulty breathing (signs of a severe allergic reaction). Â
- Chest pain, fainting, severe shortness of breath or an irregular heartbeat. Â
- New or worsening mood symptoms, severe anxiety, hallucinations or thoughts of self‑harm. Â
- Jaundice (yellowing of the skin or eyes), dark urine or severe abdominal pain (possible liver injury).
Interactions
Clinically relevant interactions to discuss with your prescriber or pharmacist:
- Hormonal contraceptives: Armodafinil can reduce the effectiveness of some hormonal contraceptives consider alternative or additional non‑hormonal contraception while taking the medicine and for a period after stopping it. Â
- CYP3A4, CYP2C19 and other enzyme substrates: Armodafinil may induce or inhibit certain liver enzymes, which can alter levels of co‑administered medicines (for example some anticonvulsants, anticoagulants, antipsychotics or antiviral agents). Â
- Warfarin and other anticoagulants: May require closer monitoring of effect. Â
- Other central nervous system drugs: Concurrent sedative medicines may have altered effects; combining with stimulants or other wake‑promoting agents should be avoided unless directed by a clinician. Â
Always provide a full medication list to your healthcare provider.
Precautions & Warnings
- Cardiovascular: Use caution if you have a history of heart disease, uncontrolled high blood pressure or arrhythmias baseline cardiovascular assessment may be appropriate. Â
- Psychiatric history: Exercise caution in patients with a history of psychosis, mania, severe depression or suicidal ideation monitor mood and behaviour closely. Â
- Substance misuse: Use caution if there is a history of substance use disorder. Â
- Pregnancy & breastfeeding: Discuss risks and benefits with your clinician. Armodafinil may affect hormonal contraceptive effectiveness and has limited safety data in pregnancy. Â
- Driving and operating machines: The medication affects alertness differently in individuals do not drive or perform hazardous tasks until you know how Waklert affects you. Â
- Pediatric use: Safety and efficacy in children should be determined by a clinician following local licensing and prescribing guidance.
