The best time to take
Modalert 200 mg Australia depends on the condition being treated. People with narcolepsy or obstructive sleep apnea are usually recommended to take Modalert in the morning to promote alertness during the day. If you are taking the tablets for sleep problems during shift work, it is best to take the tablets about an hour before the start of your shift to maintain alertness during your shift. Taking Modalert later in the day can cause insomnia or difficulty sleeping at night, as its effects can last up to 12-15 hours. Always follow your doctor's instructions for safe and effective use.
