Strattera vs. Ritalin: Dosage Differences and More

Introduction

Strattera and Ritalin are prescription medications used to treat attention deficit hyperactivity disorder (ADHD). They help decrease hyperactivity and increase focus. Although they both treat ADHD, they do so in different ways. This contributes to some differences in interactions and side effects between these two drugs.

Active ingredients, forms, and strengths

Strattera

The active ingredient in Strattera is atomoxetine hydrochloride. It’s a selective norepinephrine reuptake inhibitor that affects the chemical messenger norepinephrine. It’s thought that Strattera helps keep more norepinephrine available in the brain. This can help improve focus and concentration.

Strattera does not lead to dependence and is not likely to be abused.

Strattera is only available as a brand-name drug in immediate-release capsules. It comes in these strengths:

  • 10 mg
  • 18 mg
  • 25 mg
  • 40 mg
  • 60 mg
  • 80 mg
  • 100 mg

Ritalin

Ritalin’s active ingredient is methylphenidate hydrochloride. This is a central nervous system stimulant. It’s thought that this drug helps keep more dopamine available to the brain to help stimulate brain cells. This stimulation can improve attention and focus.

Ritalin is a federally controlled substance because it can be habit-forming and is sometimes abused.

This drug is available as both a brand-name and generic drug. Ritalin comes in several forms, listed below:

  • immediate-release tablet: 5 mg, 10 mg, 20 mg
  • extended-release capsule: 10 mg, 20 mg, 30 mg, 40 mg, 60 mg
  • extended-release tablet: 10 mg, 18 mg, 20 mg, 27 mg, 36 mg, 54 mg
  • chewable immediate-release tablet: 2.5 mg, 5 mg, 10 mg
  • chewable extended-release tablet: 20 mg, 30 mg, 40 mg
  • oral liquid: 5 mg/5 mL, 10 mg/5 mL
  • oral extended-release suspension: 300 mg/60 mL, 600 mg/120 mL, 750 mg/150 mL, 900 mg/180 mL
  • transdermal patch: 10 mg/9 hr., 15 mg/9 hr., 20 mg/9 hr., and 30 mg/9 hr.

Dosage and administration

Strattera is taken once or twice per day, with or without food. However, it needs to be taken at the same time each day. Strattera is rapidly absorbed, and maximum concentration occurs one to two hours after it’s taken. After you first start taking it, Strattera typically takes two to four weeks to have its maximum effect.

Immediate-release Ritalin is taken two to three times per day, 30 to 45 minutes before a meal. However, don’t take it right before you want to go to bed. It can interfere with sleep.

Ritalin LA is taken once per day in the morning, with or without food. For convenience, your doctor may switch you from immediate-release Ritalin to Ritalin LA if this drug seems to be working for you. After you first start taking it, Ritalin typically takes four weeks to have its maximum effect.

The exact dosage for either drug varies based on several factors. These include your weight, age, and the form you take.

Both Strattera and Ritalin can interact with other drugs. It’s important to tell your doctor about all of drugs you take, including:

  • supplements

You shouldn’t take either Strattera or Ritalin with MAO inhibitors, a type of antidepressant. You also shouldn’t take Strattera with pimozide, and don’t take Ritalin with alcohol.
