| 250 | 275 |

OTC And Prescription Aleve pills
Individuals should only use the over the counter (OTC) Naprosyn tablet for the shortest period possible. It should be taken for 3–5 days in case of pain and up to three days for fever. If there is a need for ongoing treatment, one should consult the physician first.
OTC Aleve Has Two Forms:

The Drug Comes In Various Forms, Which Are:
- Pills
- Syrup
- Injection
- Ointment
Although Naprosyn drugs are also supplied in the form of ointments, ointments aren’t as popular as its oral form but are equally effective during dental pain. The drug’s oral consumption is contraindicated in patients with gastroesophageal reflux, peptic ulcer disease, irritable bowel syndrome, or other disorders related to gastrointestinal issues. This can be prevented through the controlled release of the drug to the skin. This way, the effects of oral administered pill formula will be reduced, minimizing percutaneous absorption.
Avoiding False Generic Aleve Pills
It isn’t easy to identify any particular Aleve tablet when there are many pills with the same drugs available. Knowing how different pills and tablets look will prevent one from taking too much Naproxen or mistaking another drug for it. Also, avoid self-medication and consult with health providers to ensure the proper use of the drug, and to find suitable alternatives if necessary.
Despite the fact that Naproxen addictive properties are very low, one still may end up in a loop of addiction. In case of mild or even severe addiction, local rehabilitation centers can help patients overcome dependency. Undergoing an addiction treatment course will allow the individual to safely withdraw from the drug and mitigate the possible adverse reactions.
