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.
The maximum doses for each medication are the following: 100mg for sildenafil (Viagra), 20mg for vardenafil (Levitra) and 20mg for tadalafil (Cialis). Taking more than a prescribed dose may result in adverse cardiovascular side effects. Changing the dose of your medication without your doctor's approval is forbidden.
