OVER THE COUNTER (OTC) MEDICATIONS: A TEACHER’S COMPREHENSIVE GUIDE
Welcome, future pharmacists and healthcare professionals!
OTC drugs mean Over the Counter drugs. They are also known as non-prescription drugs and can be sold or purchased without a prescription order. OTC drugs have minimal abuse potential of the controlled constituents and contain formulations with limited amounts of few narcotic drugs, usually for anti-tussive and anti-diarrhoeal purposes. The most significant difference between non-prescription and prescription medicine is established on the availability of acceptable ways for use under which a layman can use the medicine safely.
OTC drugs are those drugs which can be purchased without a prescription. Few OTC drugs relieve aches, pains, and itches, whereas few of them prevent or treat diseases, such as tooth decay and athlete’s foot. They also help to manage migraine conditions. Few examples of OTC drugs are painkillers (like ibuprofen and acetaminophen), decongestants, anti-fungal creams, laxatives, acne creams, and sunscreens.
Dpharmguru’s exam insights:
In my years of teaching community pharmacy, I have observed that OTC medications are an essential part of pharmacy practice. Remember: OTC drugs are safe and effective when used as directed, but pharmacists must counsel patients on proper use. This is a key topic that frequently appears in exams!
NEED AND ROLE OF PHARMACISTS IN OTC MEDICATION DISPENSING
- Pharmacists have traditionally concentrated on the pharmaceutical delivery system. They provide greater services as the frequency of chronic disease, the demand for preventative treatments, and the sophisticated usage of pharmaceuticals have grown in recent years.
- When purchasing OTC drugs, pharmacists are the initial point of contact. They are required to track the usage of OTC medications in a specified group. For example, pharmacists should be extra careful in case of elderly patients who take various medications.
- They play a critical role in limiting the quantity of OTC pharmaceuticals distributed.
- They may take a more proactive approach to prevent OTC medicine misuse by employing their clinical abilities, giving oral and written medication information, and building patient trust.
- While more is being done to raise awareness about the importance of OTC medication safety and correct usage, pharmacists remain the patient’s greatest resource for good OTC product selection.
- In addition, while proper use of OTC products is important for all patients, those over the age of 65, those with pre-existing medical conditions (diabetes), children, and those currently taking prescribed medications should always seek advice from a medical professional before using OTC drugs.
- When aiding patients in choosing OTC goods, pharmacists should analyse the patient’s symptoms/condition to decide whether self-treatment is suitable or whether medical therapy is required, as well as checking for any allergies.
- Pharmacists should encourage patients who are taking multiple OTC products to always verify the active compounds of these items to prevent potential over-dosage.
- For all patients who utilise OTC drugs, pharmacists are regarded as drug experts and the primary source of drug information.
- They can also guide and give advice on OTC drugs.
- When a patient seeks advice on OTC drugs, pharmacists can take the responsibility to teach the patient on the necessity of using them correctly.
Dpharmguru’s exam insights:
A common exam question is: “What is the role of pharmacists in OTC medication dispensing?” Remember: Pharmacists are the first point of contact, track OTC usage, prevent misuse, and provide counselling. This is frequently tested!
OTC MEDICATIONS IN INDIA
The Drugs and Cosmetics Act and Rules in India identify drugs in several schedules. Drugs under Schedules H, H1, and X should have a label declaring that they are only to be sold by retail on a RMP’s prescription. Schedule G medications (mainly antihistamines) must have an obligatory wording on the label reading, “Caution: Using this preparation without medical supervision is harmful”.
Certain key drug classes, such as diuretics and aminosalicylates (sulfasalazine, mesalamine), are not covered by any drug schedule, leaving pharmacists unsure whether to market them as OTC or prescription medications. It is important to note that the term OTC has no legal meaning in India.
Common OTC Products in India

|---|---|
| Pain Relievers | Acetaminophen (Tylenol), Aspirin (Ecotrin), Ibuprofen |

COUNSELLING FOR OTC PRODUCTS
A proper OTC pharmacist-patient contact should be conducted in two steps:
Step 1: Introduction
Each pharmacist must begin OTC counselling session by introducing himself/herself by name, indicating that he/she is a pharmacist. He/she should strive to comfort the patient by making eye contact, warm smile, and a handshake at the start of the session. The pharmacist should also mention that he/she can help with OTC product selection and how to utilise it.
Step 2: Information Gathering and Counselling
To elicit key information, the pharmacist should first try to obtain relevant facts about the patient’s demography (gender, age, pregnancy, nursing, weight, allergies, social history, etc.), disease (history of current illness, current symptoms, course of illness, past history, other underlying medical conditions), and drug (current medication, medication taking history, OTC history, etc.).
Key Pharmacist Counselling Reminders
- Advise patients on proper utilisation of chosen medication, including dose, dosing intervals, mode of administration, and suggested therapy duration.
- Remind patients not to take more than the product’s suggested dosage.
- Stress the necessity of reading the labels on OTC drugs before taking them, as well as discarding expired medications.
- Encourage individuals to see a doctor if their symptoms do not improve or worsen.
- Remind patients to take OTC drugs for certain symptoms.
- Advise patients to use caution while taking numerous drugs; if they are unsure, they should seek medical advice.
- Remind patients to keep their primary care physician informed about all drugs they are taking.
Dpharmguru’s exam insights:
Remember the key counselling points for OTC products: Always check for allergies, verify active ingredients, read labels, and advise when to see a doctor. These are frequently tested in exams!
SELF-MEDICATION
Self-medication is a human behaviour in which a person self-administers therapy for medical or psychological illnesses using a substance or any outside influence. Individuals, who self-medicate, choose and utilise drugs to address self-identified ailments or symptoms.
Responsible Self-medication
Self-medication is the practice of treating illnesses and disorders with OTC drugs that are licensed and available without a prescription and are safe and reliable when used as intended.
Requirements for Responsible Self-medication:
- The medicines used must be of established safety, quality, and efficacy.
- Medicines utilised should include those for self-recognisable diseases as well as some chronic or recurring disorders (following initial medical diagnosis).
Role of Pharmacists in Promoting Safe Self-medication
- As a Communicator: Initiate conversation, ask key questions, offer objective information, and maintain confidentiality.
- As a Quality Drug Supplier: Ensure products are of excellent quality and stored properly.
- As a Trainer and Supervisor: Participate in continuous professional development and create referral protocols.
- As a Collaborator: Build positive working connections with other healthcare providers, national associations, and government.
- As a Health Promoter: Participate in community health screenings and health promotion programs.
