\u00a0<\/span><\/p>\n

Phentermine<\/span><\/a> is a prescription weight loss medication used in the short-term treatment of obesity, along with lifestyle modifications and a reduced-calorie diet. Phentermine works in the central nervous system (CNS) to cause appetite suppression. As a stand-alone product, phentermine has been around for many years.\u00a0<\/span><\/p>\n

Phentermine became popular in the 1990s, as it was once part of a popular weight loss therapy combination of fenfluramine and phentermine together. This was known as \u201cfen-phen\u201d to many back then. While the regimen was successful in aiding weight loss for many, fenfluramine specifically was later found to have fatal hypertension and heart valve effects. <\/span><\/p>\n

Fenfluramine was withdrawn from the market after billions of dollars in legal damages were awarded to survivors and victims’ families. Phentermine was not shown to have these effects and could remain on the market as a prescription appetite suppressant. Phentermine is a derivative of methamphetamine and, as such, remains a controlled substance in the U.S. market.<\/span><\/p>\n

Obesity in women<\/span><\/h2>\n

Obesity<\/span><\/a> is increasingly prevalent in the United States. One in three adults is considered \u201coverweight,\u201d with a body mass index (BMI) of 25 to 29.9. Unfortunately, even more are considered \u201cobese\u201d with a BMI over 30. Severely obese is defined as a BMI over 40, which is more likely to affect women than men. <\/span><\/p>\n

Women<\/span><\/a> have also been shown to be more affected by some of the psychological effects of obesity, such as depression and low self-esteem. While phentermine and other weight loss drugs can cause potential side effects in both male and female users, there are important factors specific to females to consider with phentermine therapy. Women are more likely to develop severe obesity, and if beginning treatment, it\u2019s important to be aware of the side effects phentermine may cause.<\/span><\/p>\n

What are common phentermine side effects in females?<\/span><\/h2>\n

Phentermine has common side effects known to occur in both men and women. These adverse events result from phentermine\u2019s action in the central nervous system. Phentermine is a stimulant related to amphetamine drugs, and it can cause restlessness, dizziness, nausea, headaches, and tremors.\u00a0<\/span><\/p>\n

Some patients may have difficulty sleeping (<\/span>insomnia<\/span><\/a>) while taking phentermine. Itching, dry mouth, and constipation have also been known to occur.\u00a0<\/span><\/p>\n

Phentermine can cause symptoms such as overstimulation, euphoria, or dysphoria in some patients. In rare cases, it can lead to psychosis. Phentermine is only indicated for short-term use and should not be taken for long periods of time.\u00a0<\/span><\/p>\n

Does phentermine cause hair loss?<\/span><\/h3>\n

Phentermine is not directly associated with hair loss, though weight loss, especially if it occurs quickly, can lead to hair loss (<\/span>alopecia<\/span><\/a>).<\/span><\/p>\n

Does phentermine affect your period?<\/span><\/h3>\n

While phentermine does not directly affect hormone levels in the body, losing a significant amount of weight can cause a fluctuation in hormone levels. This can affect menstrual cycles, making them occur either more or less frequently than before. If taking <\/span>birth control<\/span><\/a> or hormone replacement therapy, this effect may be masked.<\/span><\/p>\n

Does phentermine increase sex drive?<\/span><\/h3>\n

The indirect effect on hormone levels, coupled with <\/span>CNS stimulation<\/span><\/a>, can affect libido and sexual drive. With CNS stimulation, blood flow, and signal transmission are sometimes diverted away from the reproductive organs and genital areas to other parts of the body. In men, this can lead to impotence and erectile dysfunction, but the effects in women are different. Women tend to experience difficulty becoming aroused, delayed orgasm, or pain during intercourse.<\/span><\/p>\n
