When prescribing Bystolic your doctor will likely provide instructions on its use and inform you of its side effects. The manufacturer provides a drug information pamphlet for reference and a complete list of side effects. When you buy Bystolic online from Your Canada Drug Store, we always send the products in the manufacturer’s packaging. Your dose is based on your medical conditions and response to treatment. Bystolic works best when taken consistently, preferably around the same time, every day. If you happen to miss a dose, take it when you remember. If it is nearly time for your next dose, skip the missed one and take your next dose on schedule. Do not take a second dose to make up for a missed dose. This will not accelerate treatment and can lead to an increased risk of side effects. It can take some weeks for the medicine to take effect. Do not stop taking Bystolic once you begin to feel better. High blood pressure does not have an overt feeling of sickness, but stopping treatment too early can lead to risks to your health. If you do not see any improvement, or if your condition gets worse, contact your healthcare professional for advice.
