Isotretinoin Soft Capsules: Side Effects

Isotretinoin soft capsules belong to the retinoid class of medications. This drug reduces sebaceous gland size and suppresses sebaceous gland activity, thereby decreasing sebum production, alleviating keratinocyte hyperkeratosis and follicular-sebaceous ductal keratinous plugging, and inhibiting the growth and proliferation of Propionibacterium acnes. It is primarily indicated for severe, treatment-resistant acne. So, what are the side effects of isotretinoin soft capsules? Below is a detailed explanation.

Side Effects of Isotretinoin Soft Capsules

1. Rash

Some individuals develop a rash on their arms after taking isotretinoin capsules. In such cases, it is recommended to discontinue the medication temporarily until the rash resolves, then resume treatment if appropriate.

2. Facial dryness, cheilitis, and desquamation

Some patients report marked facial dryness as early as days 4–5 after initiating isotretinoin therapy; others experience inflammation and peeling of the lips.

3. Gingival bleeding, gastric pain, nausea, and vomiting

Other reported adverse effects include dry skin, dry lips, gastric discomfort, nausea, vomiting, and gingival bleeding. In such instances, physicians typically recommend dose reduction (e.g., switching to a lower-dose formulation such as Taisi®) to assess whether symptoms persist. If side effects do not resolve, discontinuation of the drug and close observation are advised.

4. Hallucinations and auditory hallucinations

Rarely, isotretinoin use may be associated with visual or auditory hallucinations. Discontinuation of the drug is the appropriate management in such cases.
