1 The vast majority of people will never have an anaphylactic reaction. 2  The most common causes of anaphylaxis include drugs, such as penicillin, insect stings, foods (peanuts, shellfish), X-ray dye, and latex. 3  The symptoms of anaphylaxis may vary and can include hives, tongue swelling, vomiting, and even shock.
The recommended starting dose for prolonged-release venlafaxine is 75 mg given once daily. Patients not responding to the initial 75 mg/day dose may benefit from dose increases up to a maximum dose of 375 mg/day. Dosage increases can be made at intervals of 2 weeks or more.
Trigeminal neuralgia: Slowly raise the initial dosage of 200-400mg daily until freedom from pain is achieved (normally at 200mg 3-4 times daily). In the majority of patients a dosage of 200mg 3 or 4 times a day is sufficient to maintain a pain free state. In some instances, doses of 1600mg Tegretol daily may be needed.
