Doctors usually recommend taking a 25mg to 50mg oral dose once every six hours [11] in the first trimester, while the dosage should not generally exceed 25mg in six hours during the last two trimesters [6, 7]. Use of topical Benadryl is considered safe in pregnancy as there is little evidence of harm to the fetus.
What Is the Recommended Talwin Dosage for Adults? The usual recommended dosage of Talwin in most adults is 30 mg every three to four hours. The medication can be given as an injection into a vein (an intravenous, or IV, injection), a muscle (an intramuscular, or IM, injection), or beneath the skin (a subcutaneous, or SC, injection).
Talwin is an injectable form of pentazocine, an opioid pain medication. It used to be available in an oral form, which was taken by mouth, but this form is no longer available. Currently, oral pentazocine is only available as a combination product, which means it and another medication are together in one tablet. TalwinÂ® Nx (pentazocine/naloxone) contains pentazocine in combination with naloxone (NarcanÂ®). The medication is a tablet that is taken by mouth. Naloxone is added to the drug to help prevent it from being misused via injection. Pentazocine is also available as a tablet in combination with acetaminophen (TalacenÂ®).
