If you're concerned, you should talk to your local hospital and pharmacist before you get the medication. "It's best to avoid doing certain things that could exacerbate these symptoms, such as smoking, alcohol and other drugs" "It's really common to have to get a prescription from your GP because they might not have treated your condition," adds Mark. "They may find it extremely important in the circumstances to get a prescription from your provider at a later time." For patients with pre-existing conditions, if possible, go to your GP for advice. "If you are on PDSI medication and have been taken for an extended period of time without incident, then a GP can make an appointment and refer you to an independent specialist doctor for an evaluation," says Mark. "This can be very life-changing for you, if you've had it for a longer period of time and have a better quality of life. It can also give you a sense of where your condition is before you go out and help you make better decisions." And if you're considering getting the medicines that you need, don't do it by yourself it could end up costing you significant money. Dr Mark doesn't know how many times he's had people taking all these medicines and he won't be able to tell their GP they're taking PDSI. If you have a chronic disease like diabetes or heart disease, you may need to be hospitalized or treated with antibiotics, other than the medicines that work best. You need to be monitored if you need to receive treatment for diabetes, for some type of other medical condition or for other medical conditions outside the limits listed above. If you do not need the treatment urgently, you may be at risk of becoming ill. Patients should be treated as soon as possible. If you are hospitalized, you need to be prepared to take all necessary medicines at any time.
