What medicine interact with phentermine?
Phentermine has the potential to interact with a variety of medications, including but not limited to:
Monoamine Oxidase Inhibitors (MAOIs): Taking phentermine concurrently with MAOIs can lead to a potentially life-threatening condition known as serotonin syndrome, which is characterized by symptoms such as confusion, hallucinations, rapid heartbeat, high blood pressure, fever, and tremors.
Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): These classes of antidepressants can increase the risk of serotonin syndrome when taken with phentermine.
Other Weight Loss Medications: Combining different weight loss medications, such as other appetite suppressants or drugs for obesity treatment, can lead to adverse effects and should be avoided without proper medical guidance.
Antidepressants and Anti-Anxiety Medications: Some medications used to treat depression and anxiety can interact with phentermine and potentially affect its efficacy or increase the risk of side effects.
Blood Pressure Medications: Phentermine can raise blood pressure, so combining it with medications used to treat hypertension may lead to an excessive increase in blood pressure.
Diabetes Medications: Phentermine can affect blood sugar levels, so its use with diabetes medications might require adjustments in dosages and close monitoring of blood sugar levels.
Antihistamines: Some antihistamines can interact with phentermine and potentially lead to increased heart rate and blood pressure.
Caffeine and Stimulants: Combining phentermine with other stimulants like caffeine can lead to an excessive increase in heart rate and blood pressure.
Alcohol: Alcohol consumption can enhance the side effects of phentermine, including dizziness and impaired judgment.
Certain Heart Medications: Some heart medications can interact with phentermine, potentially leading to irregular heartbeats or other cardiac issues.
Avoid taking MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before treatment with this medicationguanethidine, methyldopaphenothiazines (such as prochlorperazine, chlorpromazine),other stimulants (including amphetamines, methylphenidate, street drugs such as cocaine or MDMA/"ecstasy").
