Meridia is the brand name for the prescription weight-loss drug sibutramine hydrochloride monohydrate, which was previously available in countries including the US, Canada, and the UK. It was prescribed to people with a BMI of 30 kg/m2 or higher or those with a BMI of 27 kg/m2 or higher with cardiovascular risk factors. Meridia was withdrawn from the market in several countries in 2010 due to its association with increased cardiovascular risks and strokes. Despite this, it remains available in some countries and is still found in some unregulated dietary supplements. While it was once a popular prescription weight-loss medication, its risks have led health authorities like the FDA to recommend against its continued use.

What You'll Learn
Meridia's active ingredient, sibutramine
Meridia (sibutramine hydrochloride monohydrate) is a prescription medicine used to help overweight or obese people lose weight and maintain weight loss. It is an appetite suppressant that works as a serotonin-norepinephrine reuptake inhibitor (SNRI) similar to certain antidepressants. It was originally developed in 1988 by Boots in Nottingham, UK, and was marketed and sold under various brand names, including Meridia, Reductil, Siredia, and Sibutrex.
Sibutramine was approved by the US Food and Drug Administration (FDA) in 1997 for weight loss and weight maintenance in individuals with a body mass index (BMI) of 30 kg/m2 or higher, or for those with a BMI of 27 kg/m2 or higher who had additional cardiovascular risk factors. It was widely marketed and prescribed as an adjunct to diet and exercise for the treatment of obesity until its discontinuation in 2010.
Meridia contains sibutramine, a substance that can be addictive and has been associated with serious side effects, including increased blood pressure and heart rate, sudden death, heart failure, renal failure, and gastrointestinal problems. It is important for individuals taking Meridia to have regular check-ups and blood pressure monitoring. The use of Meridia for more than two years has not been studied, and it is not recommended for those under 16 years of age.
In recent years, the FDA has issued multiple alerts regarding dietary supplements and weight-loss products that illegally contain undisclosed amounts of sibutramine. These products are often marketed as "natural" or "herbal" remedies, and consuming them can pose serious health risks, especially for individuals with underlying medical conditions. As a result, sibutramine has been discontinued in many countries, although it may still be available in some markets.

Meridia's interactions with other medications
Meridia (sibutramine hydrochloride monohydrate) is a prescription medicine used to help overweight or obese people lose weight and keep the weight off. It is meant to be used in conjunction with a low-calorie diet and regular exercise. It is important to note that Meridia is not meant to be used for more than 2 years and its safety and effectiveness in children younger than 16 years old have not been established.
Meridia can cause serious side effects, including a large increase in blood pressure or heart rate (pulse). It is not suitable for individuals with uncontrolled high blood pressure or a history of cardiovascular issues. It is imperative that patients taking Meridia have their blood pressure and heart rate regularly monitored by a doctor.
Meridia may interact with several other medications, and these interactions can lead to serious side effects or reduce the effectiveness of one or both of the drugs. It is important to consult a doctor or pharmacist about potential interactions and never to share your medication with anyone else.
- Monoamine Oxidase Inhibitors (MAOIs): MAOIs, such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate), should not be taken within two weeks before or after taking Meridia. Combining Meridia with MAOIs can lead to serious, life-threatening side effects, including an increased risk of serotonin syndrome.
- Migraine Headache Medicines: Medications like sumatriptan (Imitrex, Imitrex Statdose) or dihydroergotamine (D.H.E 45, Migranal) may interact with Meridia.
- Ergot Medicines: Drugs such as ergonovine (Ergotrate), ergotamine (Ergomar), or methylergonovine (Methergine) could potentially interact with Meridia.
- Antidepressants: Certain antidepressants, including citalopram (Celexa), desvenlafaxine (Pristiq), duloxetine (Cymbalta), fluoxetine (Prozac, Sarafem, Symbyax), paroxetine (Paxil), sertraline (Zoloft), and venlafaxine (Effexor), may interact with Meridia.
- Sedatives, Narcotics, and Other Central Nervous System Depressants: Medications that cause sleepiness or depression of the central nervous system, such as cold or allergy medicines, sleeping pills, muscle relaxers, and medicines for seizures, depression, or anxiety, can add to the sedative effects of Meridia.
- Decongestants, Cough Medicines, and Other Diet Pills: These types of medications may interact with Meridia, and it is important to consult a doctor before taking them concurrently.
- Medications that Increase Blood Pressure or Heart Rate: Concomitant use of Meridia with other agents that increase blood pressure or heart rate, such as certain decongestants, cough medicines, and allergy medications containing ephedrine or pseudoephedrine, should be approached with caution.
- Alcohol: While a study found no significant psychomotor interactions between alcohol and sibutramine, the concomitant use of Meridia and excess alcohol is not recommended.
