Phentermine
Like any other prescription medication, Phentermine may cause side effects. For the most part, these problems will be mild and pass quite quickly. You should alert your doctor if any of the following symptoms become more pronounced or do not go away:
• any unpleasant taste or dry mouth;
• headache or dizziness;
• feeling nervous or anxious;
• insomnia;
• constipation or diarrhoea; or
• nausea or vomiting.
You should treat any of the following symptoms as serious and, if they become painful or last for any length of time, you should go to a hospital on an emergency basis. Look for:
• signs of an allergic reaction which will include increasing difficulty in breathing, and swelling to your face, tongue or throat;
• swelling in your ankles or feet;
• feeling light-headed, fainting or short of breath, even with mild exertion — or more generally, difficulty doing any physical activity within your usual range of ability;
• chest pain;
• fast or uneven heartbeat;
• unusual thoughts or behaviour, feeling restless or confused; or
• increased blood pressure which you may experience as severe headache, often accompanied by blurred vision, trouble in concentrating, numbness to your upper body or, in rare cases, seizures.
This is not a complete list of all the possible side effects. If anything else worrying does happen, contact your doctor. It is always better to be safe than sorry.
