HOW TO COPE WITH SIDE EFFECTS?
The occurrence of side effects varies from person to person. The following are a few ways of dealing with some of the common side effects. However, consult your doctor if these persist.
Coping with Nausea and Vomiting
You can help yourself by eating small, frequent meals rather than large ones and drinking plenty of fluids. Eat slowly. Avoid fatty, fried, spicy and very sweet foods. Eat cold or slightly warm food if the smell of cooked or cooking food makes you feel sick. Get plenty of fresh air. You could also try chewing ginger or drinking ginger tea. Eat bananas to replace potassium in your blood which can drop if you are sick (vomit). Use oral rehydration salts to replace vitamins and minerals lost through being sick. There are some medicines that can help you stop feeling sick. Speak to your doctor if your condition does not improve.
Coping with Headache
Make sure you rest and drink plenty of fluids. Rest in a quiet, dimly lit room. Do not sleep more than you normally would. Do not strain your eyes (for example by looking at a screen). Do not drink alcohol. Headaches are usually temporary and usually go away with time. Ask your doctor to recommend a painkiller if they last longer than a week or get worse.
Coping with Rash
There are many treatments for a wide range of skin problems. Avoid hot showers or baths because hot water can irritate the skin. Make sure to pat your skin dry after a bath or shower. Do not rub or scratch the affected area. Leave the skin exposed to the air as much as possible. Do not use perfumed soaps or deodorants. Water containing chlorine can make most skin problems worse so avoid swimming. Avoid spicy foods, alcohol, tobacco smoke and caffeine as it may also make itching worse. Avoid excessive sun exposure, always use sunscreen and protective clothing when outdoors. Moisturizers can be used regularly to soothe and hydrate the affected area. If it does not get better within a week, speak to a pharmacist or doctor.
