@sammy1998 it sounds as if you have been given some medication (two type of insulin) but no explanation about what they do beynd "reduces your bloood sugars". Maybe this works with a condition where ou just take two pills a dat and that's it but it is not the case with diabetes. I believe the best way to get the best out of insulin is to understand itr and a little biut about how your body works.
Trurapi insulin is a fast acting insulin and Levemir is a slow acting insulin.
It is very common for those of us with Type 1 diabetes (I see you have tagged this as Type 1 although you have type 2 .... maybe Type 1) to have these two types of insulin. They do not have any reaction with each other - you can take one immediately after the a=other without any impact.
You may have see reference to basal/bolus insulin regime.
Basal is the slow acting insulin. The purpose of this is to maintain a steady level in the absence of food. It works with the glucose that is constantly dripped from our liver throughout the day and night. If you google something like "Levemir profile" you should see a graph of the action/potency of the insulin. It is pretty flat.
Bolus is the fast acting insulin. The purpose of this is to work with the carbs that we eat during the day that would, otherwise, cause a spike. Trurapi is biosimilar to NovoRapid which is a very common fast acting insulin which I believe is no longer under patent. In other words, Trurapi should be the same but cheaper. If you look at the profile of Trurapi (or aspart which is the generic name for both Trurapi and NovoRapid) you will see it lasts for about 4 or 5 hours with a peak after about 30 minutes.
The two can be taken at the same time with no problem because they are doing different jobs.
I hope this long explanation puts your mind at rest about taking the two close together (or at the same time - I found it mentally easier to coincide the fast and slow acting insulins so my "insulin time" was once rather than twice).
The other thing I thought of if you are being considered to be Type 1, if you are based in the UK, is to ask for Libre. In my mind the label shouldn't matter as long as you get the right treatment. Unfortunately, the label seems to matter to those who determine what we are entitled to. So, I would advise to push for the Type 1 label because it comes with more tech such as Libre.
These are not perfect but they give you a view of the trend of your blood sugars 24/7 without having to prick your finger and get out graph paper every 5 minutes. You will then see those spikes I mentioned when you eat. Bear in mind everyone (including people without diabetes) will see a spike but with the right dose of fast acting insulin you can minimise the height and duration.
Sorry, I have waffled and strayed from your initial question. I hope it all makes sense.
