Phentramine Drug Interactions

Several medications may interact with Phentramine. Drug interactions can occur if the herbal supplement is taken with other stimulants, diabetes medications, decongestants, and other drugs. Some of these Phentramine drug interactions could increase the level of Phentramine in your blood, possibly increasing your risk of serious side effects (such as QT prolongation, a very dangerous irregular heart rhythm).

 

An Introduction to Phentramine Drug Interactions

There is very little information available about Phentramine™ drug interactions (please note that this herbal supplement is not the same as phentermine, a prescription drug). Based on what little information is available about a few of the individual components of Phentramine, it is assumed that the supplement will interact with various medicines. Some of the medicines that may lead to Phentramine drug interactions include:
 
 
 
  • Fluvoxamine (Luvox®)
  • Mexiletine (Mexitil®)
  • Monoamine oxidase inhibitors (MAOIs), such as:
 
 
  • QT-prolonging medications (medications that increase the risk of a dangerous irregular heart rhythm known as QT prolongation)
  • Theophylline (Uniphyl®, Theocron®, TheoCap®, Theo-24®, Elixophyllin®)
  • Warfarin (Coumadin®, Jantoven®).
