GPhC OTC & Self-Care 2

Question 1

A patient asks for Chloramphenicol eye drops OTC. When should they be referred to a GP?

Accepted Answer

If symptoms do not improve within 2 days or if vision is affected

Answer

OTC chloramphenicol is for bacterial conjunctivitis. Failure to improve within 2 days, pain, visual disturbance, photophobia, or contact lens wear requires GP referral for further assessment.

Question 2

Which OTC antihistamine is least sedating and therefore preferred for daytime use?

Accepted Answer

Loratadine or cetirizine (second-generation antihistamines)

Answer

Second-generation antihistamines (loratadine, cetirizine, fexofenadine) have poor CNS penetration and minimal sedating effects, making them suitable for daytime use without impairment.

Question 3

A customer requests omeprazole OTC for heartburn. For how long is it recommended before GP review?

Accepted Answer

Up to 4 weeks; refer if no improvement or symptoms persist beyond 4 weeks

Answer

OTC omeprazole (Nexium Control, Pyrocalm) is licensed for up to 4 weeks for adults with symptomatic gastro-oesophageal reflux. Persistent or worsening symptoms beyond 4 weeks require GP review.

Which OTC product is appropriate for the treatment of athlete's foot (tinea pedis)?

Accepted Answer

Accepted Answer
