Specific Precautions and Warnings With Benzphetamine
Some warnings and precautions to be aware of prior to taking benzphetamine include the following:
- Benzphetamine is chemically similar to amphetamines, which are often abused. Taking benzphetamine for long lengths of time can lead to dependence. Because benzphetamine is often abused, there are special rules for prescribing and dispensing the medication.
- Benzphetamine can increase your heart rate and blood pressure. This can cause problems, especially if you already have high blood pressure or heart problems.
- Weight loss medications like benzphetamine that work by suppressing the appetite (known as "anorectics") have been linked to pulmonary hypertension, a rare but often fatal disorder. Such medications have also been linked to valvular heart disease (diseases affecting the heart valves). People who already have a heart murmur, heart valve problems, very high blood pressure, heart disease, or an irregular heart rhythm (arrhythmia) should not take benzphetamine.
- Do not combine benzphetamine with any other weight loss medications or supplements, as doing so may increase the risk of dangerous side effects such as pulmonary hypertension.
- Benzphetamine can make glaucoma worse. Check with your healthcare provider before taking benzphetamine if you have glaucoma.
- If you have diabetes and take insulin, your healthcare provider may need to adjust your insulin dosage, as benzphetamine suppresses the appetite.
- Before you take benzphetamine, your healthcare provider should make sure your obesity is not caused by a medical problem.
- Benzphetamine may affect your ability to perform tasks that require complete concentration, such as driving, operating machinery, or piloting an airplane, especially during the first few weeks of treatment. It is recommended that you use caution until you know exactly how benzphetamine affects you.
- Benzphetamine can interact with a number of different medications (see Drug Interactions With Benzphetamine for more information).
- Benzphetamine is considered a pregnancy Category X medication. This means that it should never be used during pregnancy (see Didrex and Pregnancy).
- It is not known if benzphetamine passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the drug (see Didrex and Breastfeeding).
