### input:
Yes, I told my Doctor that I was Allergic to Phenylaline,  or the fake sugers that put Phenyl in there products.I was tested by a specialist so I know that I am.  Also whenever I drink a Diet Soda with Phenylaline in it My throat swells up and I have difficulty breathing just from one sip.  Well, it seems he is not listening or does not believe me.   Because,  my doctor prescribed Phendimetrazine  35 mg.  which is a derivative of the Phenyl products.    I do not want to end up in a Hospital.   What other medicine can he prescribe instead which is safer for me?

### output:

**1. Since you are a diagnosed allergic/hypersensitivity case for Phenylalanine thus following points are worth mentioning:. Check for PKU [Phenylketonuria] since people allergic to phenylalanine are unable to metabolize this also. Avoid phenylalanine derived food: meat, eggs,fish, cheese,products containing aspartame, almonds,beef, legumes,nuts, peanuts,pork, pumpkin/sesame seeds, soybean/flour. Even if you suspect that any medical symptoms you are having are related to an aspartame allergy, you should consult a doctor to rule out illness caused by other disease or factors.PS. Supplements are not regulated by the FDA.2. Phendimetrazine is used as a short-term supplement in the treatment of obesity, for long term proper diet and exercise are best suited.3. You may contact your Doctor for any alternate to the Chat Doctor.
