Your doctor is a person that you can completely trust when discussing your problem, and there should be no secrets whatsoever. The success of your treatment depends on how honest you are with your doctor. It’s not a secret that taking any medication can be associated with both mild and serious side effects. Sometimes these effects mean that your body is reacting positively to the treatment, while in other cases your symptoms may simply indicate you are doing something wrong. Talking to your doctor is necessary if you want to avoid side effects resulting from drug interactions of some medical conditions that you have and were supposed to be reported in advance for your health care provider to change your dose accordingly. Make sure your health care provider knows as much as possible about all your allergies and any diseases you have or used to have. The following ones are supposed to be reported to make sure they do not affect the quality of your treatment in any way: bladder muscle disorder, prostate cancer, liver disease or any other liver problems, and stricture of your urethra. Propecia is not likely to cause an allergy, but there may be people with a history of an allergic reaction to some foods or medications. You need to remember that every tablet of Propecia may contain a number of inactive ingredients. Inactive ingredients do little for the effectiveness of the pill, but they give it the shape and texture. If you are allergic to anything – make sure to read the label of Propecia very carefully and check if any of the inactive ingredients may potentially cause an allergic reaction in you. If there are safety concerns of this kind, your doctor may recommend having additional tests done in order to establish the safety of using Propecia in your particular case. Besides the medical conditions mentioned, there may be many other things for you to discuss with the doctor. You may need to share not only your personal, but also family medical history to make sure you are prescribed the right dose. If you have any health concerns or medical conditions that have been reported to interfere with Propecia, your doctor may recommend starting slowly – from a lower dose, and will be monitoring you all this time. It’s also important to tell your health care provider if you have sex with a woman that may potentially get pregnant or is already pregnant, as in that case there maybe some recommendations as well. It is not known for sure whether Propecia can pass through the condom, but small amounts of this medicine have been found in the sperm. Therefore, unprotected sex is discouraged, while using a condom may not be enough still. Your doctor will surely be able to provide a more detailed explanation for you to benefit from taking Propecia as much as possible. Make sure you always take Propecia regularly and avoid missing doses, as this can make your treatment less successful.
