Atomoxetine, also known by its brand name Strattera, is a medication primarily used to treat Attention Deficit Hyperactivity Disorder (ADHD). It's a non-stimulant medication that works by affecting certain chemicals in the brain that contribute to impulse control and hyperactivity. This article provides a detailed guide on the correct dosage of atomoxetine, its side effects, and precautions to take while using it.
Dosage Guidelines for Atomoxetine
The dosage of atomoxetine varies depending on the patient's age, weight, and medical condition. It's important to follow your doctor's instructions carefully when taking this medication. The initial recommended dosage for children and adolescents weighing less than 70 kg is approximately 0.5 mg/kg/day. The dose may be increased after a minimum of 3 days to a target total daily dose of approximately 1.2 mg/kg/day administered either as a single daily dose in the morning or as evenly divided doses in the morning and late afternoon or early evening.
For adults and adolescents weighing over 70 kg, the initial recommended dosage is 40 mg/day. The dose may be increased after a minimum of 3 days to a target total daily dose of 80 mg administered as a single dose in the morning or as evenly divided doses in the morning and late afternoon or early evening. Some patients may benefit from an increased dose up to a maximum of 100 mg/day.
Adjusting Dosage
It's crucial to remember that the dosage of atomoxetine should be individualized according to the patient's needs and responses. Your doctor may adjust your dosage based on your response to the medication and any side effects you may experience. Never adjust your dosage without consulting with your healthcare provider first.
Patients with liver impairment may need a lower dosage of atomoxetine. In patients with moderate to severe hepatic impairment, the initial and target doses should be reduced to 50% of the normal dose. In patients with end-stage renal disease, the initial and target doses should be reduced to 25% of the normal dose.
Side Effects of Atomoxetine
Like all medications, atomoxetine can cause side effects. Common side effects include stomach upset, nausea, vomiting, constipation, tiredness, loss of appetite, weight loss, dry mouth, dizziness, trouble sleeping, and sexual side effects. These side effects are usually mild and tend to go away after a few days or weeks of consistent medication use.
However, atomoxetine can also cause serious side effects. These include chest pain, shortness of breath, rapid heartbeat, dark urine, jaundice (yellowing of the skin or eyes), erection lasting more than 4 hours, and signs of a severe allergic reaction (rash, itching/swelling, severe dizziness, trouble breathing). If you experience any of these side effects, seek medical attention immediately.
Managing Side Effects
There are several ways to manage the side effects of atomoxetine. For instance, taking the medication with food can help prevent stomach upset. Drinking plenty of fluids can help prevent dehydration caused by excessive sweating. Regular exercise can also help reduce feelings of tiredness.
If the side effects persist or worsen, consult your healthcare provider immediately. They may adjust your dosage or switch you to a different medication.
Precautions When Using Atomoxetine
Before starting atomoxetine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems.
Before using this medication, tell your healthcare provider your medical history, especially of: a certain adrenal problem (pheochromocytoma), bladder or prostate problems, glaucoma, heart problems (such as irregular heartbeat, heart failure, previous heart attack, problems with heart structure), family history of heart problems (such as sudden cardiac death, irregular heartbeat), high blood pressure, liver disease, personal or family history of mental/mood disorders (such as bipolar disorder, depression, psychosis, suicidal thoughts).
Interactions with Other Medications
Atomoxetine can interact with other medications, which can affect how it works or increase your risk for serious side effects. Some drugs that may interact with atomoxetine include certain antidepressants (including other SNRIs like desipramine, imipramine), certain medications for high blood pressure (such as clonidine, guanethidine), certain medications that affect liver enzymes that remove atomoxetine from your body (such as quinidine, fluoxetine, paroxetine).
It's important to tell your healthcare provider about all the products you use, including prescription drugs, non-prescription drugs, and herbal products. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Conclusion
Atomoxetine is a valuable medication for managing ADHD symptoms, but it's crucial to use it correctly to get the most benefit. Always follow your healthcare provider's instructions regarding dosage and be aware of potential side effects and precautions. If you have any concerns or questions about atomoxetine, don't hesitate to discuss them with your healthcare provider.
Remember, everyone's experience with atomoxetine will be different. What works for one person may not work for another. It's important to work closely with your healthcare provider to find the dosage and treatment plan that works best for you.
