About Ionamin

They are available in 2 strengths – 15mg and 30mg. Ionamin is not a direct weight loss drug, it has to be combined with regular physical exercise and a healthy diet.

When is it prescribed?

Ionamin is not a regular weight loss pill; it requires a doctor’s prescription in order to be purchased used. It is a short term solution for people who are overweight. It is ideally prescribed to people who have a BMI (body mass index) of over 30. In cases where a patient’s BMI is over 27 but they have medical issues such as diabetes, hypertension and hyperlipidemia then Ionamin is prescribed.

How It Works

Like the prototype drug of it’s class, Ionamin is a sympathomimetic amine used to treat obesity. Ionamin tends to change the signals sent to the brain in order to suppress appetite, increase stimulation and elevate blood pressure. Commonly known as “anorectics” or “anorexigenics.”,  the drugs in this class aim to suppress appetite along with making other changes to the CNS and the metabolism of the patient.

Short term studies have shown that obese adults treated with the drug and a proper dietary plan lost more weight when compared to those who used placebo methods combined with dietary restrictions. The weight loss was increased only fractionally per week. However, experts have revealed that different variables not related to the drugs such as the diet, the patients, and the doctors themselves play a part in the obtained results. Thus no concrete conclusions have been made with regard to which method is better.

In both drug and non-drug related weight loss, the first few weeks show the most changes. The following time period recorded lower weight loss despite sticking to the diet and workout plans. Studies have concluded that the effects of Ionamin is similar to that of other anorectic drugs.

How to Use

Ionamin is administered orally and is to be taken either an hour before breakfast or approximately, 1-2 hours after breakfast. It is important to note that these tablets need to be taken at least 14 hours before bedtime as it is meant to keep you energized throughout the day. The pills are to be swallowed whole without being crushed or chewed on. These pills have resin to make sure that phentermine is released slowly at necessary time intervals, crushing or chewing will disrupt the functionality of the pill.  Moreover, crushing the pill will make the phentermine release all at once, making the pill ineffective and increasing the chances of side effects.
