Re: Pharmacy prices
If price is important to you it is essential to shop or phone around. Prices in chemists vary depending on their location, whether they provide a late night or 24 hour service and what additional services or facilities they provide. Also depending on what the market will bear, so if consumers are not price conscious they will end up paying higher prices.
One reason the same drug can cost different amounts for different quantities is the pack size sold by the manufacturer. Some tablets are usually prescribed for a specific period of time (5 days, a week, 30 days, whatever). If for some reason you are prescribed a regime that does not correspond with the standard pack size it may cost you more. For example if the pack size is 5 days and you need 6 days, you may end up paying almost as much as someone who needs 10 days because the chemist may not sell the remainder of the second pack and may charge you accordingly. I don't know if this explains the anomaly zag identified.
If you are worried about the cost of drugs be certain to tell the doctor who is prescribing for you. There may be a lower cost drug available for your condition. In a similar way to cars you can have a Fiesta or a Merc- both will get you from A to B and while the Merc might be nice, maybe all you really need is a Fiesta. Be honest with the doctor prescribing for you. Most people are willing to pay for an expensive drug if their doctor feels this is essential for them. Similarly, most doctors will respond sensitively if they know money is tight and will try to prescribe something less expensive when it is likely to give a satisfactory result.
Alternatively, your doctor may be able to prescribe a generic variant. Pharmacists are not allowed to substitute a generic drug unless the doctor prescribes generically. This means using the chemical name for the drug instead of the name of one of the brands of drug sold. Some types of drug treatments require that you always use the same brand, so you should not switch to a generic drug without making your doctor aware that you plan to do this. For the majority of patients generic drugs are a good alternative. You should be aware, however, that generic drugs are only available after the patent on a new drug has run out, so you will not get the most modern drugs available generically.
