Phentermine Oral Side Effects

Phentermine is a prescription appetite suppressant for use in weight loss. As with many prescription medications, there are side effects that include oral symptoms. Discontinuing use of the prescription medication typically resolves these side effects.

Eating

• Many users of phentermine have reported that their sense of taste is altered. Many have reported that to them, food either tastes bland or bad.

Unpleasant Taste

• Some users of the drug have reported a metallic or unpleasant taste that seems to linger in their mouths.

Salivation

• Users of the drug report a lack of saliva production, or dry mouth. This may include frequent thirst, a sticky sensation in the mouth and the inability to swallow.

Oral Sores

• Oral sores can be caused by bruising, cracking or biting. People taking phentermine have reported an increase in oral sores. Your dentist may be able to recommend steps to reduce the pain or frequency of sores.

Chapped Lips

• Another side effect reported is an increase of chapped or cracking lips. Users of the drug should consider treating chapped lips with a medicated lip balm.

Vomiting

• Nausea, upset stomach and vomiting have been reported in a few cases, although this side effect is not a common one.
