Tenuate Dospan can be purchased from any chemist in the United Kingdom; however, a valid doctor's prescription is required, says the Obesity Management Association. The drug can also be purchased online from several sources such as Euro Drugs Pharmacy and Online Pharmacy UK. Euro Drugs Pharmacy requires a doctor's prescription, but Online Pharmacy UK just asks for personal information and indicates an on-staff doctor needs to approve the purchase.
Tenuate Dospan is a brand name for the 75-milligram controlled-release version of the drug diethylpropion. Diethylpropion is an anorectic drug, notes Drugs.com. The drug is similar in structure and action to amphetamines, and in addition to suppressing appetite, it acts as a nervous system stimulant. It can also elevate blood pressure. Diethylpropion is indicated for short-term use for individuals with a BMI of 30 or greater who are trying to lose weight on a low-calorie diet.
Taking diethylpropion, particularly for longer than three months, is associated with an increased risk of developing pulmonary hypertension, a potentially fatal disorder. Some patients may develop a tolerance to the drug. Other patients may become psychologically dependent on it. Abrupt cessation of high doses can cause withdrawal symptoms, and the drug may cause insomnia, restlessness, irritability and hyperactivity, especially if it is taken in larger doses. High doses can produce psychosis, according to Drugs.com.
