modafinil (Modafinil) (Tablet) 100 mg/1

Modafinil is a wakefulness-promoting agent used to treat specific sleep disorders. It is prescribed for the following conditions:

• Narcolepsy: Improves wakefulness in adults with narcolepsy, a chronic sleep disorder characterized by excessive daytime sleepiness.
• Obstructive Sleep Apnea (OSA): Used as an adjunct therapy to improve wakefulness in adults with OSA, but it does not treat the underlying obstruction or medical condition causing OSA.
• Shift Work Disorder (SWD): Helps adults who experience excessive sleepiness due to working night shifts or irregular work schedules.

• Modafinil promotes wakefulness, likely through the inhibition of dopamine reuptake and activation of orexin pathways in the brain. These mechanisms help to regulate the sleep-wake cycle and reduce excessive daytime sleepiness.

Modafinil may cause various side effects, ranging from common to serious or rare. Common Side Effects:

• Headache
• Nausea
• Dizziness
• Nervousness
• Insomnia
• Dry mouth

Serious or Rare Side Effects

• Skin rash, hives, or blistering, which may indicate a severe allergic reaction
• Difficulty breathing or swallowing
• Fever, shortness of breath, swelling of the legs, yellowing of the skin or eyes, or dark urine, which may indicate liver problems
• Severe mood changes or depression
• Hallucinations or confusion

Modafinil should be used with caution and under medical supervision. Important precautions include:

• Allergic Reactions: Avoid use if you have had an allergic reaction to modafinil, Provigil, armodafinil, or Nuvigil.
• Liver Problems: Monitor for signs of liver problems, such as yellowing of the skin or eyes, dark urine, or persistent nausea.
• Mental Health: Be aware of potential mood changes, including depression, anxiety, or hallucinations.
• Pregnancy: Consult your doctor before use, as modafinil is categorized as Pregnancy Category C.
• Drug Interactions: Inform your doctor of all medications you are taking to avoid potential interactions.
• Storage: Store at room temperature between 20°C and 25°C (68°F and 77°F); excursions permitted from 15°C to 30°C (59°F to 86°F). Keep out of the reach of children.

Modafinil can interact with other medications, potentially affecting their efficacy or increasing the risk of side effects. Major Interactions (Avoid):

• CYP3A4 Inducers: Avoid concurrent use with strong CYP3A4 inducers, as they may reduce modafinil's effectiveness.
• CYP3A4 Inhibitors: Avoid concurrent use with strong CYP3A4 inhibitors, as they may increase modafinil's concentration in the blood.
• Warfarin: Avoid concurrent use, as modafinil may alter warfarin's anticoagulant effects.

Moderate Interactions (Monitor Closely)

• Hormonal Contraceptives: Monitor for reduced effectiveness of hormonal contraceptives when taken with modafinil.
• Antiepileptic Drugs: Monitor for changes in seizure control when taken with modafinil.
• Antidepressants: Monitor for increased risk of side effects, such as serotonin syndrome.
