Obesin Dosage

How times a day do you take this medicine?

Dosage of Obesin in details

infoThe dose of a drug and dosage of the drug are two different terminologies. Dose is defined as the quantity or amount of medicine given by the doctor or taken by the patient at a given period. Dosage is the regimen prescribed by the doctor about how many days and how many times per day the drug is to be taken in specified dose by the patient. The dose is expressed in mg for tablets or gm, micro gm sometimes, ml for syrups or drops for kids syrups. The dose is not fixed for a drug for all conditions, and it changes according to the condition or a disease. It also changes on the age of the patient.

Important Information Prior To Initiating Treatment

Prior to treating children, adolescents, and adults with CNS stimulants, including Obesin, assess for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam).

Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy. Maintain careful prescription records, educate patients about abuse, monitor for signs of abuse and overdose, and periodically re-evaluate the need for Obesin use.

General Dosing Information

Obesin should be orally administered once daily in the morning with or without food. The dose should be individualized according to the needs and responses of the patient. Before administering the dose, shake the bottle of Obesin.

In children 6 years of age and older, start with 2.5 mg or 5 mg once daily in the morning. The dose may be increased in increments of 2.5 mg to 10 mg per day every 4 to 7 days up to a maximum dose of 20 mg per day.

Pharmacological treatment of ADHD may be needed for extended periods. Healthcare providers should periodically re-evaluate the long-term use of Obesin, and adjust dosage as needed.

Switching From Other Obesin Products

If switching from other Obesin products, discontinue that treatment, and titrate with Obesin using the above titration schedule.

Do not substitute for other Obesin products on a milligram-per-milligram basis, because of different Obesin base compositions and differing pharmacokinetic profiles.

Dosage Modifications Due To Drug Interactions

Agents that alter urinary pH can impact urinary excretion and alter blood levels of Obesin. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust Obesin dosage accordingly.

Before taking Obesin, tell your doctor if you are taking any of the following medicines:

  • insulin or another medicine to treat diabetes;

  • guanethidine (Ismelin) or reserpine (Diutensin-R);

  • doxazosin (Cardura), terazosin (Hytrin), prazosin (Minipress), or guanadrel(Hylorel);

  • a tricyclic antidepressant such as amitriptyline (Elavil), amoxapine (Asendin), doxepin (Sinequan), nortriptyline (Pamelor), imipramine (Tofranil), clomipramine (Anafranil), protriptyline (Vivactil), or desipramine (Norpramin)

  • a phenothiazine such as chlorpromazine (Thorazine);

  • lithium (Lithobid, Lithonate, Eskalith, others); or

  • haloperidol (Haldol).

You may not be able to take Obesin, or you may require a dosage adjustment or special monitoring during treatment if you are taking any of the medicines listed above.

Obesin interactions

infoInteractions are the effects that happen when the drug is taken along with the food or when taken with other medications. Suppose if you are taking a drug Obesin, it may have interactions with specific foods and specific medications. It will not interact with all foods and medications. The interactions vary from drug to drug. You need to be aware of interactions of the medicine you take. Most medications may interact with alcohol, tobacco, so be cautious.

Drugs Having Clinically Important Interactions With Amphetamines

Table 2: Drugs having clinically important interactions with amphetamines.

MAO Inhibitors (MAOI)
Clinical Impact MAOI antidepressants slow Obesin metabolism, increasing amphetamines effect on the release of norepinephrine and other monoamines from adrenergic nerve endings causing headaches and other signs of hypertensive crisis. Toxic neurological effects and malignant hyperpyrexia can occur, sometimes with fatal results.
Intervention Do not administer Obesin during or within 14 days following the administration of MAOI.
Examples selegiline, isocarboxazid, phenelzine, tranylcypromine
Alkalinizing Agents
Clinical Impact Increase blood levels and potentiate the action of Obesin.
Intervention Co-administration of Obesin and gastrointestinal alkalinizing agents should be avoided.
Examples Gastrointestinal alkalinizing agents (e.g., sodium bicarbonate). Urinary alkalinizing agents (e.g. acetazolamide, some thiazides).
Acidifying Agents
Clinical Impact Lower blood levels and efficacy of amphetamines.
Intervention Increase dose based on clinical response.
Examples Gastrointestinal acidifying agents (e.g., guanethidine, reserpine, glutamic acid HCl, ascorbic acid). Urinary acidifying agents (e.g., ammonium chloride, sodium acid phosphate, methenamine salts).
Tricyclic Antidepressants
Clinical Impact May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d-Obesin in the brain; cardiovascular effects can be potentiated.
Intervention Monitor frequently and adjust or use alternative therapy based on clinical response.
Examples desipramine, protriptyline
Proton Pump Inhibitors
Clinical Impact Time to maximum concentration (Tmax) of Obesin is increased compared to when administered alone.
Intervention Monitor patients for changes in clinical effect and adjust therapy based on clinical response.
Example omeprazole

Drug/Laboratory Test Interactions

Amphetamines can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening. Amphetamines may interfere with urinary steroid determinations.

Drug Abuse And Dependence

Controlled Substance

Obesin contains Amphetamine, which is a Schedule II controlled substance in the U.S. Controlled Substance Act (CSA).


Obesin, is a CNS stimulant that contains Amphetamine which has a high potential for abuse. Abuse is characterized by impaired control over drug use, compulsive use, continued use despite harm, and craving.

Signs and symptoms of Obesin abuse may include increased heart rate, respiratory rate, blood pressure, and/or sweating, dilated pupils, hyperactivity, restlessness, insomnia, decreased appetite, loss of coordination, tremors, flushed skin, vomiting, and/or abdominal pain. Anxiety, psychosis, hostility, aggression, suicidal or homicidal ideation have also been observed. Abusers of amphetamines may use other unapproved routes of administration which can result in overdose and death.

To reduce the abuse of Obesin, assess the risk of abuse prior to prescribing. After prescribing, keep careful prescription records, educate patients and their families about abuse and on proper storage and disposal of CNS stimulants, monitor for signs of abuse while on therapy, and re-evaluate the need for Obesin use.



Tolerance (a state of adaptation in which exposure to a drug results in a reduction of the drug's desired and/or undesired effects over time) may occur during the chronic therapy of CNS stimulants including Obesin.


Physical dependence (which is manifested by a withdrawal syndrome produced by abrupt cessation, rapid dose reduction, or administration of an antagonist) may occur in patients treated with CNS stimulants including Obesin. Withdrawal symptoms after abrupt cessation following prolonged high-dosage administration of CNS stimulants include dysphoric mood; fatigue; vivid, unpleasant dreams; insomnia or hypersomnia; increased appetite; and psychomotor retardation or agitation.
