Phentermine vs Contrave

When it comes to weight loss medications, phentermine and Contrave are two popular choices.

Phentermine is a short-term appetite suppressant that delivers quick results, making it an ideal option for those looking for a fast fix.

On the other hand, Contrave is a slower weight loss medication that is perfect for long-term usage, with its effects extending for a longer duration.

Both medications work by reducing food cravings and calorie intake, making the weight loss journey more manageable.

This article will delve into the mode of action and side effects of these medications, along with clinical trials and user reviews that provide insights into their efficacy.

So, keep reading until the conclusion to learn everything there is to know about these two weight loss medications.

To begin, a basic ingredient analysis will be performed to determine how these medications work.

What is Phentermine?

Phentermine is a sympathomimetic amine that has gained popularity as an anorectic drug for treating obesity.

It is sold in the market under various names such as Phentermine HCL, Adipex-P, and Lomaira, but one thing remains the same: it can be purchased only with a prescription from a physician.

The drug works by targeting synaptic receptors in the brain and raising levels of certain neurotransmitters that help suppress appetite.

Its short-term treatment approach has provided hope for those struggling to lose weight. Its effectiveness, however, comes with possible side effects and requires close monitoring from medical professionals.

Despite this, Phentermine has proven to be a valuable tool in battling obesity for those who qualify for its use.

What is Contrave?

Orexigen Therapeutics developed Contrave, a prescription weight-loss supplement, which Currax Pharmaceuticals purchased in 2019.

Containing bupropion HCl and naltrexone HCl, this supplement has been commonly prescribed to those with a body mass index of 30 kg/m2 or higher.

Bupropion, primarily used as an antidepressant, has been known to promote weight loss when used as monotherapy, while naltrexone is an opioid antagonist used to reduce cravings for alcohol or opioids.

The two molecules work together to stimulate parts of the central nervous system, such as the hypothalamus and mesolimbic system, to suppress appetite and cravings, as well as affect the limbic reward system.

Although the exact neurochemical effects of this supplement are not fully understood yet, it has become a popular option for those struggling with weight loss.

Which is safer and more effective, phentermine or contrave?

Both diet pills claim to provide excellent results, but which should you choose? And, in the first place, are these anorectic medications safe?

To help you make an informed decision, we have gathered a list of their benefits, side effects, and user reviews.

Phentermine benefits

Phentermine is a powerful weight loss medication that offers many benefits to those struggling with extra pounds.

The medication’s hunger-curbing effects last up to 2 to 3 days, ensuring that individuals feel full and satisfied for extended periods.

This effect is due to the medication’s long half-life and its influence on serotonin and norepinephrine levels.

In a 12-week study, over 80% of participants exhibited a 5% reduction in initial weight, with more than half reporting up to 10% weight loss.

Phentermine also has mild positive effects on metabolism, increasing energy expenditure at rest by up to 35%.

Lastly, the medication’s impact on dopamine levels enhances mood and energy, making individuals feel more positive and motivated throughout the day.

Contrave benefits

Contrave is a prescription medication that has been proven to aid in weight loss. It works by targeting specific brain circuits, namely the hypothalamus and mesolimbic circuits, to help suppress the hunger response and reduce cravings.

Additionally, Contrave increases dopamine levels in the brain, which can lead to a feeling of fullness with fewer bites.

In fact, a 2010 placebo-controlled study found that users taking Contrave lost 6.1% more weight than those taking a placebo.

This medication not only helps with weight loss, but it also has mood-improving effects due to the increased presence of dopamine in the brain upon use of bupropion.

With proven results and a multi-faceted approach, Contrave can be an effective tool in achieving weight loss goals.

When it comes to achieving weight loss goals, Phentermine is often top of mind for those seeking a quick fix.

With its intense stimulative properties, it provides quicker effects than other weight loss medications.

However, it’s important to remember that sustainable weight management requires more than just a pill.

Healthy habits like a balanced diet and regular physical activity are necessary for long-term success.

For those seeking a medication that can aid in both short and long-term weight loss goals, Contrave may be a beneficial option.

It allows for lifestyle and eating habit modifications during use, making it a valuable tool for those looking to achieve lasting results.

How safe is Phentermine?

Phentermine is a well-known drug that is FDA-approved for short-term usage of up to three months.

Despite its effectiveness in reducing weight for healthy individuals, phentermine’s status as a controlled substance limits its usage to only a few months.

On the other hand, Contrave, another weight loss medication, has received approval for long-term usage since none of its ingredients fall under controlled substances.

Although it is generally well-tolerated by healthy individuals, phentermine can pose serious health risks to pregnant women and those with underlying cardiovascular or cerebral problems.

Thus, it is crucial to consult with a healthcare professional before taking any medication to ensure one’s safety and well-being.

How safe is Contrave?

The safety of Contrave was closely monitored in a clinical trial involving 3475 individuals to assess its adverse effects.

Users reported typical side effects such as nausea (32.5%), constipation (19.2%), and headache (17.6%).

However, less than 10% of users experienced other adversities, and a negligible risk factor for cardiovascular ailments was indicated in the study.

While Contrave is generally safe, it is important to note that serious side effects such as suicidal thoughts, liver damage, vision problems, or manic behavior may occur after taking this medicine.

Due to their impact on brain cells, these side effects are comparable to those of naltrexone, bupropion, and phentermine.

It is essential for individuals to speak with their doctor before taking Contrave and to report any unusual symptoms that might develop.

Side effects of Phentermine

Phentermine is a widely used weight loss drug, but like any medication, it comes with a list of possible side effects.

Common side effects include nausea, insomnia, headache, dry mouth, palpitations, tachycardia, constipation, and thirst.

However, more severe side effects have been reported, such as pulmonary hypertension, cardiovascular diseases, and stroke.

According to scientific findings, using phentermine may also cause cardiac problems such as ventricular fibrillation and heart arrhythmias, as well as cerebral stroke and tardive dyskinesia.

Moreover, taking large doses of phentermine over an extended period of time has been linked to psychotic behavior and anti-social thoughts and interactions.

Pregnant or breastfeeding women should also avoid taking phentermine due to the risk of gestational diabetes and complications.

Side effects of Contrave

Contrave is a commonly prescribed medication for weight loss, but as with any drug, it comes with potential side effects.

Nausea, headache, dry mouth, dizziness, constipation, vomiting, sleep disturbance, and diarrhea are among the most common side effects of Contrave.

It’s important to note that serious side effects like depression, mania, hepatitis, angle-closure glaucoma, and severe allergic reactions may also occur.

Additionally, it’s worth mentioning that Contrave can reduce the efficacy of opioid-based medications and street drugs.

If you’re considering taking Contrave, make sure to tell your doctor about all other medications you use before beginning the medication.

This is especially important for pregnant women as it falls under category X and is unsuitable for breastfeeding mothers due to potential harm to infants.
