Celexa, or citalopram, is a selective serotonin reuptake inhibitor prescribed to treat depression. Other SSRI medications include Prozac, Paxil, Zoloft and Lexapro. Celexa and other SSRIs treat depression by blocking the reabsorption of serotonin in the brain, thus increasing serotonin levels. Like all drugs, Celexa may cause a range of side effects. Some of these may go away after the initial period of treatment, while others will persist throughout treatment. Understanding the possible side effects can help patients know what to expect from treatment.
Dry Mouth
Twenty percent of patients taking Celexa experience dry mouth, according to RxList.com. For many people, this lack of sufficient saliva persists throughout treatment. While posing no serious risks, dry mouth can cause discomfort, bad breath, difficulty eating and speaking and dental problems. Mayoclinic.com explains that saliva limits bacterial growth and washes away food and plaque, thus preventing tooth decay and oral infections. Adequate saliva production also enhances the sense of taste, enables swallowing and aids in digestion. Mayoclinic.com suggests dealing with dry mouth by chewing sugar-free gum, avoiding sugar and caffeine and using a humidifier while sleeping.
Sexual Dysfunction
Many people experience sexual dysfunction while taking antidepressants, including with Celexa. For men, this can include impotence or abnormal ejaculation. Women may experience delayed or abnormal orgasm or the inability to reach orgasm. Both genders can suffer from diminished libido. RxList points out that researchers are not clear on the incidence of sexual problems because of the hesitance of both patients and doctors to talk openly about this issue.
Nausea
More than 20 percent of people taking Celexa experience nausea, making this the most common side effect of the medication. Nausea may or may not subside after the initial phase of treatment. Other gastrointestinal symptoms may accompany the nausea including flatulence, vomiting and diarrhea. Taking Celexa with food may help reduce these side effects. MayoClinic.com additionally suggests eating bland food and regularly drinking cool, clear liquids or mint tea in addition to getting plenty of fresh air to combat nausea.
