Phentermine should only be used for short-term use (less than 12 weeks at a time) to help with weight loss. It works by activating your sympathetic (“fight or flight”) nervous system, so it's called a “sympathomimetic” drug or “stimulant.”
The combined drug is approved for long-term use. Phentermine is approved for use for up to 12 weeks.
TAKE-HOME MESSAGE
Longer-term use, >12 months, was associated with significantly more weight loss (7.4%) than a duration of use < 3months and a risk of CVD or death comparable with that associated with a shorter-term use.
Phentermine 37.5 continuous use for 6 months could reduce 5-7% body weight, while some people witnessed more value than this. A person who weighed around 200 pounds, he/she could lose 10-14 pounds with phentermine within 90 days time frame.
Many doctors prescribe phentermine, on its own, to patients for more than 12 weeks. But there's a lack of research on its longer-term safety and efficacy. It is available as an inexpensive generic medication, but concerns have been raised about addiction and cardiovascular side effects.
If you're taking phentermine long term, your doctor may suggest a 90-day supply of the medication. This will have to be approved by your insurance company. Getting a 90-day supply could help lower the drug's cost. It could also save you time having to make trips to your pharmacy.
You should not take Duromine for more than 3 months. After that, it may not work as well as before. You should not drink alcohol while taking Duromine. Alcohol can make Duromine less effective and cause more side effects.
While phentermine is only FDA-approved for short-term use (12 weeks), many healthcare providers prescribe the medication off-label for more long-term use. Or, your healthcare provider may prescribe phentermine intermittently, which means you take a break from the medication before returning to it.
Phentermine works by suppressing your appetite, but it does not directly cause weight loss. Losing weight depends on you creating a calorie deficit, which means burning more calories than you consume each day. Aim for a 500 to 1000 calorie deficit per day through diet and exercise to lose about 1-2 pounds in a week.
Phentermine may cause weight gain after people stop taking it. Studies show that 80 percent of patients regain some or all of their lost weight after two years. Therefore, people nearing the end of their prescriptions must think carefully about their next steps.
Phentermine has marginal effects on the menstrual cycle many patients of Phentermine 37.5 mg experienced irregular menstrual periods. This is the same effect observed from the use of phenate which interferes with a group of hormones called Catecholamine.
Some patients become hungrier around 3-4 months because they stop following the diet as closely and they start eating foods that stimulate the appetite. Phentermine is still working, but eating the wrong foods can stimulate your appetite more than phentermine will suppress it.
Phentermine has the ability to suppress your appetite alongside increasing your metabolism. When you eat less and burn more calories, it's a good bet that you'll lose weight quickly. That's why many dieters find phentermine so helpful.
After phentermine diet, it is a must to maintain a long-term healthy lifestyle that involves nothing but a balanced diet and exercise regularly. Having 7-8 hours' sleep time every day is useful to shed excessive pounds while keeping the risks of side effects at bay.
Phentermine should only be used for short-term use (less than 12 weeks at a time) to help with weight loss. It works by activating your sympathetic (“fight or flight”) nervous system, so it's called a “sympathomimetic” drug or “stimulant.”
Due to its stimulatory effects, the risks of side effects increase over time and with higher dosages. Potential side effects include increased heart rate, insomnia, and elevated blood pressure. Phentermine can also become addictive if used long-term or at high doses.
Do not suddenly stop using phentermine. Suddenly stopping phentermine treatment can cause seizures. It can also cause withdrawal symptoms.
Phentermine may be used short-term as an aid to weight loss; however, it can be addictive and tolerance may develop to its weight-losing effects, rendering it less effective with time.
Concerns about longer-term phentermine use include increased risk of cardiovascular disease (CVD) (6, 17) and potential for addiction (22).
Duromine is not the same as normal Phentermine drugs, because it has a special technology that makes the drug go into your blood slowly. The slow release of the drug makes the effects of Duromine last longer. This makes you feel less hungry for longer. Phentermine HCL is a fast-acting and one-time release drug.
If you suddenly stop using this medication, you may have withdrawal symptoms (such as depression, severe tiredness). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used phentermine for a long time or in high doses.
