I started taking 30mg of phentermine about four months ago. It worked really well until about a month ago. So I went to the dr at the beginning of February and he up it to 37.5mg. Will the up in dosage work or is the body already immune to it?

Hello lulu8402. No, not according to the chemical make up of the drug. Phentermine is perscribed to work for a very short period of time. Two to three weeks. The longer taking the drug, the less effective it is. And the very likelyhood and common side effects in doing so are can be serious. Cardiac/blood pressure issues are two. Regards pledge
