Every individual is unique in that every person has a different body size, and different metabolism. Some bodies can burn or gain fat easily while it takes others considerable efforts to lose even a small amount of fat. Because of this and different medical needs, a physician must determine how much phentermine is needed based on possible reaction to the drug. Phentermine, if taken in correct dosage with a few precautionary measures might be a very effective drug for most people.

In the initial stages or in case of overt obesity, phentermine pills might be recommended for twice a day usage. When this is the case, the pill must be taken before breakfast on an empty stomach. The tablet is to be taken as it is or can be broken if the dosage is lesser but must not be crushed or chewed under any circumstances. If phentermine is taken in the morning, it can help control hunger throughout the day or at least till the next dosage. Dosage can vary in the morning if hunger seems lesser.

One side effect of phentermine pills is insomnia, so the tablet should be taken at least 6 hours before bedtime.

Never take a double dosage if one dosage is skipped. It would not matter in the long run if one dosage is skipped but it might produce severe reactions if a double dosage is taken. These reactions include radically increased heart rate, postive-to-negative mood swings , and erratic ways of thinking. Always consult your doctor.
