Phentermine, marketed under various brand names such as Adipex-P, Suprenza, and Acxion, is commonly prescribed as a short-term remedy for obesity. It belongs to the class of appetite suppressants, aiming to curb hunger and facilitate weight loss in individuals with obesity or overweight issues. Phentermine efficiently decreases food intake by stimulating the release of specific brain chemicals that control appetite, ultimately resulting in weight reduction.
Common Side Effects of Phentermine
While this medicine can be an effective tool for weight management, it’s important to be aware of potential adverse reactions that may accompany its use. Here are the top 9 Phentermine side effects you need to know.
Reduced saliva production, a common side effect of Phentermine, can lead to dry mouth, potentially causing discomfort, difficulty swallowing, and susceptibility to dental issues such as tooth decay. It’s necessary to maintain adequate hydration by drinking plenty of fluids while taking Phentermine. Additionally, avoiding overly sweet or salty foods may help alleviate dry mouth symptoms.
Phentermine’s stimulant effects can disturb regular sleep patterns, causing trouble falling asleep or staying asleep, a condition often known as insomnia. This side effect is often experienced by individuals taking Phentermine, particularly if the medication is taken later in the day. It is recommended to take this medicine in the morning or early afternoon, allowing the medication to wear off by bedtime.
Phentermine’s effects on blood vessels can result in shifts in blood flow to the brain, leading to the onset of headaches in some individuals. These headaches depend on intensity and duration. Staying well-hydrated is crucial in managing headaches associated with Phentermine use. Additionally, over-the-counter (OTC) pain relievers such as acetaminophen or ibuprofen can help alleviate headache symptoms.
- Tremor
Some individuals taking Phentermine may experience trembling or shaking, which can be a temporary and mild side effect of the medication. However, persistent tremors or shaking may indicate that the dosage of Phentermine is too high and should be adjusted accordingly. It is important to note any accompanying symptoms, such as rapid breathing, confusion, or stomach cramps, as these may signal a more serious reaction to the medication.
- Behavioral Shifts
Phentermine’s influence on specific brain chemicals can result in mood and behavioral changes in certain individuals. While some may encounter feelings of euphoria or increased energy levels, others might express agitation. Given its classification as a controlled substance due to potential misuse and dependence, Phentermine warrants cautious use, particularly among individuals with a history of substance misuse. This caution extends to some Phentermine side effects in females, emphasizing the importance of careful monitoring and open communication with healthcare providers regarding any observed effects.
- Gastrointestinal Complications
Gastrointestinal disturbances such as constipation or diarrhea may occur as side effects of Phentermine use. These effects are attributed to the medication’s impact on the digestive system. To alleviate constipation, maintaining adequate hydration and incorporating fiber-rich foods into the diet can help promote regular bowel movements. Over-the-counter (OTC) medications like stool softeners or laxatives may also be used under the guidance of a healthcare provider.
- Sexual Dysfunction
One of the many Phentermine side effects in males involves implications for sexual function, potentially causing changes in libido or erectile dysfunction in some individuals. These sexual side effects can be distressing and impact the quality of life. It is important for individuals experiencing such symptoms to communicate openly with their healthcare professional to discuss potential underlying causes and explore appropriate management options.
- Cardiovascular Effects
Phentermine’s stimulant properties can have cardiovascular effects, including increased heart rate and elevated blood pressure. While Phentermine-induced weight loss may lead to improvements in blood pressure levels, it is important for individuals taking Phentermine to monitor their cardiovascular health regularly, particularly if they have a history of heart problems. A healthcare provider should promptly evaluate symptoms like shortness of breath, chest discomfort, or palpitations to rule out any serious cardiac issues and ensure appropriate management of Phentermine therapy.
- Heart and Lung Disorders
Individuals with pre-existing heart or lung conditions should exercise caution when considering Phentermine therapy due to potential risks associated with its use. Patients with a history of cardiovascular diseases such as stroke, arrhythmias, or heart failure may be susceptible to adverse cardiovascular events while taking Phentermine. Furthermore, individuals who have a medical history involving lung conditions should undergo careful monitoring for respiratory risks and are encouraged to promptly report any new or worsening signs to their healthcare provider.
Phentermine Withdrawal Symptoms
Extended or excessive use of Phentermine can lead individuals to become reliant on the drug, potentially triggering withdrawal symptoms when they stop. Recognizing these symptoms is crucial in preparation for managing them or seeking medical assistance.
Fatigue
Phentermine, being a stimulant, increases energy levels and alertness. However, once the drug is discontinued, the brain undergoes a period of adjustment, resulting in feelings of drowsiness and fatigue.
Weight Gain
Phentermine suppresses appetite, often resulting in weight loss during use. Upon discontinuation, weight gain can occur due to increased appetite and reduced physical activity, although individual lifestyle choices also play a role.
Low Mood
Changes in mood, including bouts of sadness, are common during Phentermine withdrawal. This adjustment period involves the brain returning to its normal state, which can be particularly challenging for individuals with pre-existing mental illnesses such as depression.
Drug Cravings
Mental cravings for Phentermine may arise due to fatigue and low mood experienced during withdrawal. Whether it be Suprenza or Acxion pill or any brand name variation of Phentermine, individuals may yearn for the drug’s effects, such as increased energy and happiness.
While Phentermine withdrawal symptoms cannot always be entirely avoided, speaking with a healthcare professional about gradually discontinuing the drug can help alleviate them.
Contacting a Healthcare Professional
Staying connected with your healthcare provider while taking Phentermine is essential. Whether it’s trouble sleeping, mood changes, or stomach discomfort, your doctor can provide personalized advice to help manage these issues effectively. In cases of severe adverse reactions like chest pain, dizziness, or difficulty breathing, seeking immediate medical attention is crucial. Your healthcare provider is here to support you and ensure your safety while taking Phentermine, so don’t hesitate to reach out if you need assistance.
Doctor’s Recommendation

- Allergic reactions: rash, hives, itching, swelling, difficulty breathing or swallowing.
- Signs of acidosis: confusion, difficulty breathing, irregular heartbeat, severe stomach pain, extreme drowsiness, shortness of breath, fatigue.
