Fastin, generic name phentermine, is a prescription-strength appetite suppressant used as a short-term treatment method for obesity. It is not recommended for individuals who simply want to lose a few pounds. Instead, it is used to jump start weight loss for individuals who are seriously overweight. According to Drugs.com, while using the medication individuals should be learning ways to lose weight for the long term.
Step 1
Read the directions and product description carefully. Determine which dosage you have been prescribed. The directions may explain that this is a once-a-day medication or it may have been dispensed in the three tablets per day dosage.
Step 2
Take one capsule of Fastin with a full glass of water an hour before breakfast. If you forget to take the dose before breakfast it can be taken one hour after eating. Fastin dispensed as a three times per day medication should be taken 30 minutes before breakfast, lunch and dinner, with a full glass of water.
Step 3
Continue taking the medication as prescribed. In addition to the medication, follow the diet and exercise routine as discussed with your medical care provider. Fastin alone will not produce lasting results.
Step 4
Check in with your doctor often while taking this medication. Long-term usage is not recommended, as it is an addictive drug.
