A. Following your prescriber's instructions for both the amount of the medication you should take (for example, 20ml once a day) and the length of time you should take it (for example, every day for 3 months) is the best thing you can do to ensure a successful course of treatment. We understand that some medications may have unpleasant side effects or may be difficult to administer. Therefore, our pharmacists and nurses are available to offer practical advice about dealing with these issues or to contact your prescriber about the medical management of these side effects.
