Healthcare users can be assisted by a medicine or drug recommendation system (MRS) by understanding their needs and supporting informed decisions based on complex knowledge. The biggest challenge is analyzing users' sentiments, as human language characterizes user-generated data in many complex ways.

This paper proposes a sentiment analysis (SA)-based drug recommender system using an optimized deep learning (DL) model with an enhanced transformer-based feature representation mechanism. The proposed system comprises four stages: preprocessing, feature extraction, classification, and medicine recommendation. Firstly, drug reviews collected from public repositories are pre-processed to improve data quality. In the feature extraction stage, the pre-processed data are fed into the Multi-Head Attention Bidirectional Encoder Representations from Transformers (MHABERT) model to capture deep semantic and contextual features. The user sentiments are then classified using Golden Jackal Optimized Bidirectional Long Short-Term Memory (GOBLSTM). Finally, medicine recommendations are generated by comparing the similarities of drug reviews.

The Kaggle medicine recommendation and Yelp health datasets are used to evaluate the proposed method. Experimental results demonstrate maximum accuracies of 98.43% and 98.30% on the Kaggle and Yelp datasets, respectively, outperforming existing approaches.

The combination of SA and drug recommendation enhances patient outcomes, optimizes medicine selection, and reduces adverse reactions.
