Caffeine can increase the side effects of this medication. Taking phentermine when your thyroid is untreated puts excess strain on your adrenals which can ultimately make thyroid function worse. Remember that your thyroid gland and adrenals are intricately linked! Because of this I don't recommend taking Phentermine unless you are currently being adequately treated with Thyroid hormone and you have addressed your adrenals.
For patients that see me in my office who have been untreated I recommend they use thyroid medication with adrenal support for at least 4 weeks before adding phentermine. If you answered Yes to any of these questions then I don't recommend that you start taking Phentermine until these are addressed! For many patients that means changing to a thyroid medication that contains T3 hormone - either NDT or Liothyronine. If you answered yes to any of these questions I don't recommend starting phentermine right away.
As I said before, phentermine by itself doesn't actually balance your hormone levels and lead to lasting weight loss But it does have some interesting side effects that we can exploit to make balancing your hormones easier. Currently in my practice I only recommend using Phentermine for patients who have one or more of the following diagnoses: By far the most beneficial side effect of phentermine is its ability to reduce appetite.
This side effect can be VERY helpful in patients who suffer from intense food cravings like those with Leptin Resistance or in patients who need to be on fasting protocols because of Insulin Resistance. As you may know the key to reversing insulin resistance is reducing insulin levels, and there is no better way than fasting. Once insulin levels drop low enough your body begins to burn purely fat cells as an energy source.
Using phentermine in this way makes it so patients are only using it days per week for intermittent fasting , or days in a row for more prolonged fasting periods. Do you see the difference between using this medication by itself for weight loss and using this drug to balance other hormones for weight loss? Most people believe that taking the medication will reduce their appetite which means they won't eat as much which means they will lose weight.
The biggest mistake you can make is using phentermine to reduce your calories for a prolonged period of time while still eating poor quality foods - just less of them. This WILL result in further thyroid damage and weight gain once you stop the medication. Traditional advice is to take the medication daily for several months, then stop it. I've even seen some patients on it for as long as 12 months. If you are taking it long term which I don't recommend make sure that you only use it 5 days out of the week, and take a 1 month break every 2 months.
Doing this will allow your receptors to re-sensitize to the medication and keep it working for you longer. If you experience these side effects you can try reducing the dose by half, or even taking the medication every other day or only on fasting days! But don't continue taking them if the symptoms don't resolve, it's not worth impairing other systems in your body to lose a couple of pounds.
In my patients I wait until they have been on adrenal support AND thyroid support with T3 medications for at least 4 weeks before I start phentermine. If you have low grade adrenal fatigue I recommend starting with adrenal glandulars. Having said that it can be used to help balance other hormones in your body and ultimately lead to weight loss.
My favorite side effect of this medication is appetite suppression which can be used in conjunction with fasting to reverse insulin resistance and leptin resistance which will lead to lasting weight loss. Even though it can be helpful in some people it can also cause more harm than good, especially if it's used in patients who are being under treated for their thyroid or in patients with untreated adrenal fatigue. That's why I don't recommend taking this medication unless you are also on thyroid medication and adrenal support.
