Naxen is available in tablets, as a topical cream, and as an injectable. The best place to inject naxen is in the gluteus maximus because it requires a deep intramuscular injection. Naxen does have some side effects which include: heartburn, constipation, nausea, diarrhea, dizziness, fatigue, depression, rashes on your skin, heart attack, muscle weakness, and fever.
Naxen is a little on the high side when it comes to price. For a package of 45x20 mg tablets which would last about 10 days at 600-mg/2x day, it is about $12.00. On the black market this would probably be around $15 - $18.
