Why am I using Duromine? What is it used for?
For those who are overweight, the anorectic medication Duromine may be helpful as a short-term supplement to behavioural modification, physical activity, and calorie restriction. A Body Mass Index (BMI) of 30 or over is widely recognized as an indication of obesity. People with a body mass index (BMI) of 25 to 29.9 who are overweight and at an increased risk of morbidity may also begin taking Duromine. A doctor should rule out any underlying organic secondary causes of obesity before giving the medicine.
Body Mass Index Calculator

BMI is calculated by dividing your weight in kilograms by your height in metres squared.

This calculator has been reviewed by NeverGiveUpTeam experts and is based on reputable sources of medical research. It is not a diagnostic tool and should not be relied on as a substitute for professional medical or other professional health advice.

How do I take Duromine?
How much to take
- It's common to take only one pill every day. Your doctor will specify the right dose.
- Capsules should be taken orally with water and swallowed whole. Keep capsules sealed.
- Follow your doctor's instructions for Duromine use.
- Dosing up may not result in more rapid or more significant weight reduction. Negative consequences, however, are more likely to occur.
When to take Duromine
- You may prevent staying up late by taking Duromine with breakfast.
- Duromine is most effective when taken at the same time every day. It helps in remembering to take it. It may be taken before or after eating.
If you forget to use Duromine
- Duromine should be used on a daily basis. If you miss a dosage before breakfast, make up for it by midday.
- Taking Duromine after lunch may cause insomnia. If your next dose is almost due, skip the missing dose. Do not duplicate the dosage to make up for a missing one.
If you use too much Duromine
You may need urgent medical attention if you think you have taken too much Duromine.

So dry mouth and insomnia are leaders among side effects. Not so bad!
Special thanks for the pictures. I was wondering what the drug looks like
Wow, I didn’t know the small medication could have such severe negative effects!
While on Duromine, I am unable to work out cause I’m too tired. It happened every time I took the drug ( I did it several times). The article suggests seeking medical attention in this case. But I don’t see what can be done by the doctors here.
One time, I gave someone else a dose of the medicine I was taking. Well, she already had the prescription. That’s really not a huge issue.
It’s so frustrating that I need to announce to the world that I take the drug. That really irritates me. Does anybody feel me?
There are so many things I didn’t know so far. Likely, I need to take this more seriously and make an appointment with my doctor…
Hold on a sec. You may take tablets even before a morning meal? Isn’t that weird?
Thanks, that’s helpful. Side-effects information was beneficial. Everything’s in one spot!
