2 What to Know Before Using
Before using Aplenzin, you must know all about the risks and complications associated with it. The suitable drug therapy is usually chosen by a doctor with the active participation of the patient.
There are some important factors such as drug interactions, the presence of any metabolic impairment, history of hypersensitivity reaction, pregnancy, lactation etc. which may alter the desired therapeutic effects of a medicine.
Sometimes the presence of other health disorders affects the beneficial effects of this medicine and even may cause serious toxic effects.
If you have had any allergic reactions to any medicine then you must tell your doctor about that. The use of bupropion is contraindicated in those who are hypersensitive to this drug or any of the ingredients of the formulation.
Make sure you inform your doctor if you have any medical problem and drug history, especially:
Because of drug-drug interactions, certain medicines should not be used along with this medicine. It is always recommended to consult with your doctor if you are in need of some other medications or even any over-the-counter medicine for another health problem in order to avoid unwanted toxic effects.
Besides, the following drug interactions should be kept in mind:
Bupropion inhibits CYP2D6 and can increase concentrations of antidepressants (e.g. venlafaxine, nortriptyline, imipramine, desipramine, paroxetine, fluoxetine, sertraline), antipsychotics (e.g. haloperidol, risperidone, thioridazine), beta-blockers (e.g. metoprolol), and Type 1C antiarrhythmics (e.g. propafenone, flecainide). Consider dose reduction when using with bupropion.
An increased dose may be necessary if concurrently administered with CYP2B6 inducers (e.g. ritonavir, lopinavir, efavirenz, carbamazepine, phenobarbital, and phenytoin) based on clinical response, but should not exceed the maximum recommended dose.
CNS toxicity can occur when dopaminergic drugs (levodopa and amantadine) are used concomitantly with bupropion.
Increased risk of hypertensive reactions can occur when monoamine oxidase inhibitors (MAOIs) are used concomitantly with bupropion.
Bupropion can cause false positive urine test results for amphetamines.
Animal reproduction studies have shown an adverse effect, and there are no adequate and well-controlled studies in pregnant women. Thus, this drug should be used during pregnancy only if clearly needed.
Besides, caution should be exercised when used in lactating women because there are no adequate studies in women for determining infant risk when using this medication during breastfeeding.
3 Proper Usage
To use Aplenzin properly, you must follow all instructions given by your doctor. The dosage schedule and the duration of drug therapy should be individualized and determined based on the doctor’s advice.
The therapeutic dose may also vary with the patient’s condition or requirement and the strength of the medicine as well. This medicine comes with patient information.
You should read and follow the instructions carefully before using this medicine. It is generally agreed that acute episodes of depression require several months or longer of antidepressant drug treatment beyond the response in the acute episode.
The recommended starting dose is 200 mg per day, given as 100 mg twice daily. After 3 days of dosing, the dose may be increased to 300 mg per day, given as 100 mg 3 times daily, with at least 6 hours between successive doses.
A maximum of 450 mg per day, given in divided doses of not more than 150 mg each, may be considered for patients who show no clinical improvement after several weeks of treatment at 300 mg per day. To minimize the risk of seizure, increase the dose gradually. Increases in dose should not exceed 100 mg per day in a 3-day period.
If you miss a dose of this medicine, take it as soon as possible. But, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use this drug in larger amounts, more often, or for a longer time than your doctor ordered.
Further, it is advised to store the medicine in a closed container at room temperature away from heat, moisture, and direct light. All kinds of medicines should be kept out of the reach of children. However, outdated medicines should be disposed of by an appropriate way.
