Phentermine is a prescription drug that helps to lose weight in the short term. It acts by decreasing the appetite through central nervous system stimulation. It can be used with diet and lifestyle modifications to decrease the number of calories. Phentermine is a stimulant hence it needs to be taken under close medical guidance. The question that many patients raise is whether the results can be improved by taking phentermine 37.5 mg two times per day.

What is Phentermine 37.5 mg?
Phentermine 37.5mg is a prescription drug that has been used to manage short term weight. It is usually prescribed to obese people or those with weight problems who have health complications. Phentermine is an agent that activates the central nervous system. This causes the release of more neurotransmitters which suppress appetite.
Consequently, the patients might not be hungry during the day. The usual dosage prescribed by the FDA is 15 to 37.5mg as a single dose. It is normally consumed in the morning to prevent insomnia. The drug needs to be administered under the care of a medical practitioner since there are side effects and the likelihood of dependence.
Can Phentermine Be Taken Twice Daily?
Phentermine is usually administered in the form of a daily drug. The conventional medical practice does not allow more than one morning dose. This is a method that can curb the feeling of hunger as well as minimise stimulant side effects. Daily intake of two doses of phentermine is not advisable. An overdose or repeated use of a drug may lead to the chance of high blood pressure, a fast heartbeat, anxiety, and insomnia.
Most of the patients have a sufficient duration of action with the medication. When appetite reappears later in the day, the clinicians tend to change diet policies and not the frequency of doses. Only a licensed healthcare provider should make any change in the dosing after the appropriate assessment.
