As a patient with a renal condition there are sometimes problems with buying medicines over the counter to treat minor ailments i.e. from pharmacies, supermarkets or garages. This is relevant whether you have poor renal function, are on dialysis or have a transplant.
The word medicine includes tablets, capsules, liquids, inhalers, or creams that either your doctor gives you or that you buy.
Aspirin and Ibuprofen belong to a group of medicines called Non Steroidal Anti-Inflammatory Drugs (NSAIDs). Diclofenac is another NSAID available from your doctor. NSAID’s can be very harmful to kidneys, so if you have a transplant or have poor renal function not requiring dialysis all NSAIDs should be avoided. Take care not to take one NSAID given to you by your doctor and another one that you have bought.
You may have a number of medical conditions and are therefore prescribed several medicines from your doctor. As a result, some of the medicines that can be bought over the counter from pharmacies and other shops may be unsuitable for you.

Problems that may happen with medicines that you can buy
• They may cause problems with other medicines you take.
• Some may make your kidney function worse.
• Some products contain things that are bad for you, like potassium, sodium or aluminium.
However, if you talk to your doctor or pharmacist, it should still be possible for you to buy suitable medicines to treat minor ailments.

Some points to remember when buying medicines
• It is very important to tell any doctor or pharmacist recommending a medicine for you about your renal condition and the medicines you are taking.
• You should only treat minor ailments by yourself for a few days. If your symptoms change, get worse or last for more than a couple of days, see your doctor.

• Be aware that some of the tablets your doctor gives you can also be bought over the counter. Be careful not to take double the dose.
• Remember to tell the pharmacist if you are diabetic or have had an allergic reaction to any medicine.
• Try to use the same pharmacy so that the pharmacist can build up a complete picture of all the drugs you are taking. He/she will then be able to provide you with the best advice.
• If you find that you need to treat the same symptoms frequently, please do not forget to mention them to your doctor at your next visit.
• When the renal team ask which medications you take, include those you buy yourself.
• Be careful not to take more than one preparation with Paracetamol in - do not forget that Co-codamol and Co-proxamol (Distalgesic) contain Paracetamol.
• Effervescent tablets are best avoided because they contain sodium.
• If you have a transplant try not to take any indigestion remedies for one hour before or after your transplant medicines.
• You should remember that, although some medicines are not recommended for you to buy, they may be safe for your doctor to prescribe them.
