Prescription of L-Arginine

Generally, L-Arginine can be taken without a prescription from your doctor.

In fact, it can be readily bought over the counter at health stores in the form of supplements.

However, this does not mean that you can take  L-Arginine freely.

You should always consult with a health professional to determine if you can take it safely and in what dosage.

Even though Arginine is an amino acid that is naturally produced by the body and is present in many foods, there is still the possibility of adverse side effects for certain people, as well as negative interactions with particular prescription drugs you may be taking.

Some basic rules you must apply although is not must prescription.

  • When you talk to your doctor about taking L-Arginine, you should explain to him what you are taking it for.
  • He may recommend alternatives that are more effective.
  • If the doctor approves of your starting an L-Arginine routine, he will also recommend a maximum daily dosage that you should not exceed to ensure that there are no side effects.
  • If you are currently already taking an L-Arginine supplement or are about to take one, bring a sample during your consultation.
  • The doctor will read the label and determine how much L-Arginine content there is per suggested dosage and may recommend that you take more or less depending on your particular health condition.

If you are taking L-Arginine to treat erectile dysfunction, your doctor may recommend a version that is combined with PDE-5 inhibitors, which will require a prescription to buy.
PDE-5 is used to treat ED, but high doses of it may cause blushing.
Combining it with L-Arginine means that less PDE-5 can be used in the combination to reduce the likelihood of blushing. In addition, those who cannot take PDE-5 due to contraindications may be able to take an L-Arginine/PDE-5 combo since there is less of the latter in the formulation.
