General Information about Celexa and Lexapro
Celexa is an antidepressant drug in the class of medications known as selective serotonin re-uptake inhibitor. These medications affect the chemicals used by the nerves in the brain to communicate with each other. These chemicals are usually referred to as neurotransmitter and Celexa functions by stopping the uptake of serotonin, one of the neurotransmitters, after being released. Due to the fact that uptake is a crucial mechanism for eliminating the released neurotransmitters and stopping the actions on other nerves close by, the uptake caused by Celexa provides a freer serotonin within the brain to fuel the nerve cells. There are other SSRIs that works on serotonin in the brain among which are Paxil (Paroxetine), Prozac (Fluoxetine), and Zoloft (Sertraline).
Lexapro is an approved oral medication that is usually prescribed for the treatment of general anxiety disorder and depression. It is also used off label for the treatment of obsessive compulsive disorders.

Drug Interaction with Celexa and Lexapro
Celexa and Lexapro are SSRI drugs and as such should not be used with any monoamine oxidase inhibitor (MAOI) type of antidepressants. For instance, you should not use either of these medications with Marplan (Isocarboxazid), Parnate (Tranylcypromine), Nardil (Phenelzine), Matulane (Procarbazine), and Eldepryl (Selegiline). Combining either Celexa or Lexapro with any of these drugs can lead to high blood pressure, confusion, hyperactivity, and tremor. Before a change in treatment between Celexa and other MAOI can be made, there should be a period of a fourteen days' interval between usages.
Dietary supplements such as Tryptophan can cause nausea, headaches, dizziness or sweating when taken with Celexa or Lexapro. Do not use intravenous Methylene blue and Linezolid with either of the two drugs. Non-steroidal anti-inflammatory medications, Aspirin, and other drugs that can affect bleeding should also not be used with Celexa or Lexapro because they can increase the risk of upper gastro-intestinal bleeding. Drugs that increase serotonin within the brain should also be avoided when using these two drugs. Medications such as Lithium (Eskalith, Lithobid), Sumatriptan (Alsuma, Imitrex), Tramadol (Ultram), and Meperidine (Demerol) should also not be combined with them.
Celexa has been reported to cause complications during the third trimester of pregnancy. It is therefore important to stay away from the drug when pregnant. It has also been reported that the drug may pass into breast milk. You should therefore not take Celexa if you are nursing a baby. There is not much evidence to show the danger of using Lexapro during pregnancy or nursing. However, for safety reasons, it is recommended that you don't take the drug if pregnant or nursing a baby.
