Can i take claritin (loratadine) and phentermine together?

Yes: Claritin (loratadine) is an antihistamine which would help reduce the runny nose, itchy nose and sneezing. Phentermiine would help reduce the congestion. However the combination is likely good for only mild allergic conditions.

Dr Paudel agreed

Claritin (loratadine) Yes, -D No: Claritin (loratadine) is a non-sedating antihistamine, used to treat allergy-related symptoms. Phentermine is an appetite suppressant. Claritin ; Phentermine can usually be taken together safely. However, claritin-d contains the decongestant, pseudoephedrine. Both Pseudoephedrine and Phentermine are stimulants. Taking both can increase side-effects, like palpitations, agitation, hypertension.
