It is not recommended for people with current or past heart or blood pressure problems, addiction, agitation, hyperthyroidism, glaucoma or MAOI use. Given that this a prescription medication, you can only buy phentermine after a doctor has examined you and decided that this medication is a safe and appropriate choice for you.
Phentermine’s active ingredient (phentermine HCl) is a controlled substance, so it is not legal to buy or take phentermine without a current doctor’s prescription. Always take exactly as prescribed and do not share your medication with anyone else.
