Overview Of Phentermine

Advice For Taking It

Phentermine needs to be taken around the same time each day. Patients who take it three times per day should take each dose roughly thirty minutes before breakfast, lunch, and dinner. Individuals who take it once a day should take their dose either before breakfast or one to two hours after breakfast. If the patient forgets to take a dose, they should skip the dose for that day if it is late in the afternoon or evening. Taking two doses at one time could cause serious side effects, and it may be fatal. In addition, taking the last dose too late in the day increases the risk of insomnia and other side effects related to sleep.
