With summer now upon us, it is important that we know how to keep our medicines safe
\nand effective in the warmer temperatures.<\/p>\n
All medicines carry an instruction on the label advising that they must be stored below a
\ncertain temperature. This is because some medicines lose their effectiveness when
\nstored above a certain temperature, and this can result in lost or reduced effectiveness.<\/p>\n
Some even may change form and become difficult to use. For instance, gelatine
\ncapsules may soften, ointments and creams may become runny, and suppositories may
\nmelt.<\/p>\n
If you are in an area of regular and prolonged high temperatures your medicines should
\nbe stored in the coolest, safest place available.<\/p>\n
Storing medicines safely is particularly important if you are travelling over the summer
\nmonths. Do not leave medicines in cars. Even in the boot, glovebox or console the
\ntemperature in a car can exceed 50\u00b0C in summer which can affect the active ingredient
\ncontained in medicines.<\/p>\n
A slight reduction in the efficiency of pain relievers such as ibuprofen or paracetamol
\nmay not present a major problem.<\/p>\n
However, for patients taking medicines for chronic illnesses such as diabetes, heart
\ndisease, epilepsy or anti-coagulant therapy, taking damaged medicine may mean that
\nmanagement of the condition is reduced. This may lead to harmful consequences so
\nproper storage in a cool place is essential.<\/p>\n
Medicines are also required to have an expiry date printed on the label, and while this
\ndoes not mean that after this date the medicine is suddenly useless or dangerous, it
\ndoes indicate that after the \u201cexpiry date\u201d the quality and effectiveness of the medicine
\ncannot be guaranteed.<\/p>\n
Some medicines, including some commonly used analgesics, produce unpleasant or
\ntoxic products when they degrade. A common example is aspirin which breaks down
\nover time to acetic acid and salicylic acid. These components can cause stomach
\nirritation if people take the medicine after the expiry date.<\/p>\n
Blister or foil-packed products are more likely to maintain their integrity than tablets or
\ncapsules packed loosely in a bottle if they stored in below-optimum conditions for a
\nshort time. For medicines you only use occasionally, it may be better value to purchase
\nsmaller packs of blister-packed medicines, instead of larger pack sizes.<\/p>\n
If you believe your medicine may have been exposed to higher-than-recommended
\ntemperatures or may be out of date, speak to your community pharmacist.<\/p>\n
It is also advisable to check with your pharmacist about storing your medicine in the
\nfridge as most medicines should not be stored at these temperatures.<\/p>\n
If a medicine label says it should be stored in the fridge, it means the main
\ncompartment, not the freezer. If your medicines accidentally freeze, they are almost
\ncertainly unstable and therefore should not be used. Once again, check with your
\npharmacist.<\/p>\n
Most bathrooms have a \u201cmedicine cabinet\u201d and so the natural tendency is to store
\nmedicines in the bathroom, but this is actually one of the worst places to keep them.
\nMedicines should be stored in a cool, dry place and not a bathroom where the heat and
\nmoisture from the shower, bath, and sink may damage them with the result they may
\nbecome less effective.<\/p>\n
In general, it is important to try to store medicines away from heat, moisture and
\nsunlight. Most medicines should be stored below 25\u00b0C and they should never be left in
\nwarm places such as in front of a window where the temperature can reach high levels.<\/p>\n
People living in the tropics should store their medicines in a part of the house that is
\ncool and dry; for example in an airtight container in a dark cupboard. They should be
\nchecked regularly to see that they remain dry, especially during the wet season.<\/p>\n
And if you have to take your medicines while out and about, take with you only what you
\nneed for the day, and leave the remainder at home. Your community pharmacy can
\nassist you with products to help you safely carry a few doses of a medicine; they can
\nadvise on any storage, expiry or medicine stability questions; and they can dispose of
\nany expired or heat-affected medicines you may have.<\/p>\n
Always check the label for storage instructions, and talk to your pharmacist if you have
\nany questions.<\/p>\n","protected":false},"excerpt":{"rendered":"
