Is phentramine safe for weight loss?

Phentermine Danger: Nope. It is very dangerous to your heart. It is also dangerous to your brain because there is no real or lasting weight loss but the person taking the drug can become obsessed about staying on it just like an addict. There is a fear that weight gain will result if one stops this ineffective and dangerous drug.

Not really safe: Phentermine is a stimulant agent very similar to amphetamines and meth. It is potentially addictive, causes insomnia, anxiety, tremor, sweating and high blood pressure. Other drugs like it have been shown to increase heart attacks, strokes and sudden cardiac death. I would not recommend this agent. Diet and exercise should be first line, and there are other drugs available if those don't work.

Safe enough to be: Considered FDA approved(for whatever that's worth). It has real adverse effects including increased heart rate, blood pressure, insomnia, dry mouth, constipation, and nervousness. Many stimulants have either failed to receive FDA approval or been removed from the market after initial approval related to safety concerns. It should only be used if absolutely necessary.

Phentermine: Phentermine is relatively safe for weight loss if your blood pressure and pulse are normal and you don't have any underlying heart disease or strokes. Most doctors will not prescribe it longer than 6 months at a time and monitor patients carefully each month by checking blood pressure and pulse and symptom check and making sure the patient is avoiding caffeine or other stimulants.
