Can i take phentermine with antibiotics

Phentermine is a stimulant that is used for weight loss. It works by suppressing your appetite and increasing your energy levels. Antibiotics, on the other hand, are used to treat bacterial infections. If you are prescribed both phentermine and antibiotics, you may wonder if it is safe to take them together.

Can I take phentermine with antibiotics?

The answer to this question depends on the specific antibiotics and phentermine that you are taking. Some antibiotics can interfere with the effectiveness of phentermine, while others can increase the risk of side effects. It is essential to talk to your doctor about any medications you are currently taking, including phentermine, before starting a course of antibiotics.

Antibiotics that may interact with phentermine

Some antibiotics can interfere with the effectiveness of phentermine by decreasing its absorption into the body. These antibiotics include:

Tetracycline
Chloramphenicol
Erythromycin
Rifampin

If you are taking any of these antibiotics, your doctor may recommend that you stop taking phentermine until your course of antibiotics is finished.

Antibiotics that may increase the risk of side effects

Other antibiotics can increase the risk of side effects when taken with phentermine. These antibiotics include:

Fluoroquinolones
Macrolides
Cephalosporins

If you are taking any of these antibiotics, your doctor may recommend that you start with a lower dose of phentermine or monitor you closely for side effects.

Alternatives to phentermine

If you are taking an antibiotic that interacts with or increases the risk of side effects with phentermine, your doctor may recommend an alternative weight loss medication. Some alternative weight loss medications include:

Liraglutide
Orlistat
Phendimetrazine
Bupropion/naltrexone

These medications work differently than phentermine and may be a safer option when taking antibiotics.
