Weight loss is a common goal for many, and phentermine has become a popular aid in the pursuit of shedding those extra pounds.

However, like any medication, it comes with its own set of potential side effects, one of which may include increased sweating.

In this blog post, we’ll explore the connection between phentermine and sweating and provide practical advice for managing this side effect while you continue your weight loss journey.

Understanding Phentermine and Sweating

Phentermine is a prescription medication that suppresses appetite, which can be an effective short-term weight loss solution. It stimulates the central nervous system, which can increase heart rate and blood pressure and, as a result, may lead to increased sweating.

The Physiology of Sweating

Sweating, or perspiration, is primarily a cooling mechanism that helps to maintain body temperature. When your internal temperature rises, your sweat glands release moisture onto the skin’s surface. As this moisture evaporates, it cools the body.

The Science Behind Sweating on Phentermine

Phentermine acts as an appetite suppressant primarily through its effects on the central nervous system. It releases chemicals in the brain that mimic the stress response, often referred to as the ‘fight or flight’ response, which can increase body temperature and, consequently, sweating.

This thermogenic effect can be beneficial for weight loss but may be uncomfortable for many.

A study conducted by the National Institutes of Health found that increased sweating was reported among the side effects of phentermine use, although it did not specify the prevalence.

According to a recent online poll conducted by phentermine.com, 43% of all respondents indicated that they feel they are sweating more since starting phentermine ( 1 ).

Coping with Increased Sweating

If you’re experiencing increased sweating while taking phentermine, there are several strategies you can employ to manage this side effect.

Stay Hydrated

Increased sweating can lead to dehydration. Ensure you’re drinking plenty of water throughout the day to replenish lost fluids.

Wear Appropriate Clothing

Opt for lightweight, breathable fabrics like cotton or moisture-wicking materials that can help absorb sweat and keep you cool.

Maintain Good Hygiene

Shower regularly and consider using an antiperspirant to help control sweat and body odor.

Adjust Your Environment

Keep your living and working spaces cool with fans or air conditioning, and avoid high-temperature environments when possible.

Monitor Your Diet

Spicy foods, caffeine, and alcohol can all contribute to increased sweating. Monitor your intake of these substances to see if reducing them helps manage your sweating.

Mindful Breathing

Stress can exacerbate sweating. Techniques such as deep breathing or meditation can help manage stress levels, potentially reducing excessive sweating.

Regular Exercise

While it may seem counterintuitive, regular physical activity can improve your body’s efficiency in regulating temperature and may reduce sweating episodes over time.

Medical Interventions

In some cases, your doctor may prescribe anticholinergic drugs that reduce sweating. However, due to potential side effects, these should be used with caution and under strict medical supervision.

When to Speak to Your Doctor

If excessive sweating becomes a concern or is accompanied by other symptoms, it’s important to consult with your healthcare provider.

They may adjust your dosage or suggest alternative weight loss solutions.
