Cocktail therapy medication consultation


Hello Dr.
Zhang,
Recently, someone introduced me to a weight loss medication, which is the most popular DNC cocktail weight loss method in the United States.
Since it has been described as a medication, I am hesitant to take it without caution.
Could you please explain the effects of these medications and whether the dosages are appropriate? Thank you.
I am 18 years old, 160 cm tall, and weigh 69 kg.
- CC-0147 capsule: 1 capsule every morning
- Redufat capsule: 1 capsule every morning
- Metformin 500 mg: 1 tablet before lunch and 1 tablet before dinner
- Bontril 35 mg: 1 tablet before lunch
- Xenical: 1 capsule before dinner every other day
Additionally, I am currently taking birth control pills.
Will there be any side effects if I take these medications together? Thank you for your response.

Dr. Zhang Jinteng reply Pharmacology


Hello, in response to your question regarding weight loss medications, metformin and xenical are both marketed drugs in Taiwan.
However, I could not find any information on CC-0147, Redufat, and Bontril on the website of the Pharmaceutical Administration, so I cannot provide information on these three medications.
From a pharmaceutical perspective, it is essential to communicate closely with your primary care physician regarding their use for weight loss.
Metformin is primarily an antidiabetic medication that can delay the gastrointestinal absorption of glucose, enhance glucose sensitivity, promote peripheral tissue uptake of glucose, and inhibit hepatic gluconeogenesis.
If taken without food, it may cause gastrointestinal discomfort such as nausea, vomiting, and diarrhea.
The maximum daily dosage for antidiabetic medications is 2550 mg, so your dosage is within the normal range.
Regarding xenical, this medication is a gastrointestinal lipase inhibitor that prevents the active enzyme from hydrolyzing dietary fats into absorbable free fatty acids and monoglycerides, thus inhibiting triglyceride absorption.
The recommended method of administration is to take one 120 mg capsule during a meal or within one hour after eating.
Common side effects include gastrointestinal issues such as oily spotting (staining of clothing), bloating, urgent bowel movements, oily stools, increased bowel movements, and fecal incontinence.
There are no known interactions between metformin and xenical with oral contraceptives.

More Info


The DNC cocktail weight loss method has gained popularity as a weight loss strategy, particularly in the United States. However, it is crucial to understand the medications involved, their mechanisms of action, potential side effects, and interactions with other medications, especially since you are only 18 years old and currently taking birth control pills.


Overview of the Medications
1. CC-0147 and Redufat: Unfortunately, there is limited information available regarding these two medications. They do not appear to be well-documented in medical literature or regulatory databases. It is essential to approach these medications with caution, as their safety and efficacy are not well established.

2. Metformin (500 mg): This medication is primarily used to manage type 2 diabetes by improving insulin sensitivity and reducing glucose production in the liver. In the context of weight loss, Metformin can help some individuals lose weight, particularly those with insulin resistance. Common side effects include gastrointestinal issues such as nausea, diarrhea, and abdominal discomfort. Your dosage of 500 mg before meals is within the normal range, as the maximum daily dose can go up to 2550 mg, depending on individual tolerance and physician guidance.

3. Bontril (35 mg): This is a brand name for phendimetrazine, a stimulant that suppresses appetite. It is typically prescribed for short-term weight loss in conjunction with a reduced-calorie diet. Side effects can include increased heart rate, elevated blood pressure, insomnia, and potential dependency. It is crucial to monitor your response to this medication closely.

4. Xenical (Orlistat): This medication works by inhibiting the absorption of dietary fats in the intestines, leading to reduced caloric intake. Common side effects include gastrointestinal discomfort, oily stools, and flatulence. It is essential to take Xenical with meals containing fat to maximize its effectiveness. The recommended dosage is one 120 mg capsule taken with each main meal, and taking it every two days may not provide optimal results.


Potential Interactions with Birth Control Pills
Regarding your concern about taking these medications alongside birth control pills, there is generally no direct interaction between Metformin, Bontril, or Xenical and hormonal contraceptives. However, weight loss can sometimes affect the metabolism of contraceptive hormones, potentially impacting their effectiveness. It is advisable to consult with your healthcare provider to ensure that your birth control method remains effective while you are on these medications.


Risks and Benefits
The potential benefits of this cocktail may include weight loss and improved metabolic health. However, the risks cannot be overlooked. The combination of multiple medications can lead to increased side effects, and the long-term safety of using unverified drugs like CC-0147 and Redufat is unknown. Additionally, the psychological impact of weight loss drugs, including dependency and body image issues, should be considered.


Conclusion
Before starting any weight loss regimen involving medications, it is crucial to consult with a healthcare professional who can provide personalized advice based on your health history and current medications. They can help you weigh the risks and benefits, monitor your health, and adjust your treatment plan as necessary. Remember, sustainable weight loss is best achieved through a balanced diet and regular physical activity rather than relying solely on medications.
