As Viagra is now so easy to get having a prescription is not always necessary although it is often in your best interest to go and speak to your GP to have a health check up before going ahead with the medication to make sure that your erectile problems are not caused by any underlying health conditions.
There are two sorts of prescriptions which you can have for Viagra, a private prescription or an NHS prescription. To get an NHS prescription you must go and see your GP so that they can assess whether or not you are suitable for the medication and then if you are eligible for a prescription on the NHS. You will only be able to get a Viagra prescription on the NHS if you fall into one of these categories;
If you do not fall into one of these categories you will then have to seek a private prescription. A private prescription is not funded by the NHS and so you will have to pay the full amount for the medication and often the charge of the pharmacy which supplies it.
Any doctor can prescribe you a private prescription for Viagra, although your GP can only give you a private prescription if the medication you want is not available to you on the NHS. It is often the case that if you go to get a private prescription from an alternative doctor they charge you for their time.
A private prescription can be used more than once as long as the doctor has authorised repeat prescriptions and the pharmacist will then just stamp the prescription each time you go so you know how many times you have had your medication given to you.
