If you miss a dose by a fairly short amount of time, take it as soon as you remember. However, if it’s almost time for your next dose, then just skip the missed dose and get back on schedule at your next regular time. Never take a double dose to “catch up.” Also, taking a missed daily dose too late in the day may cause you to have trouble sleeping that night.
If you somehow take an extra dose of Phentermine, it can result in an overdose.
Symptoms include the following:
- restlessness
- tremor
- rapid breathing
- mental confusion
- hallucinations
- feelings of panic
- nausea and/or vomiting
- diarrhea
- feeling belligerent
- irregular heartbeat
- seizures
If you have any of these symptoms, seek medical attention right away. Never take more Phentermine than is prescribed or take it for a longer period than prescribed because you think it will help you lose extra weight.
All medicine—including Phentermine—should be stored tightly closed in
the container it came in. Store it at room temperature,
away from heat, light and moisture. Make sure it is out of reach of children.
