From the Guidelines
It is generally safe to take terbinafine and corticosteroids at the same time, but you should always consult with your healthcare provider before combining these medications. Terbinafine is an antifungal medication used to treat fungal infections of the nails, skin, or hair, while corticosteroids are anti-inflammatory medications used to treat various conditions including allergic reactions, skin disorders, and autoimmune diseases. The two medications work through different mechanisms and typically don't have significant interactions with each other, as noted in the study by 1. However, both medications can affect the liver, so your doctor may want to monitor your liver function if you're taking them concurrently. Additionally, corticosteroids can sometimes mask or worsen certain fungal infections, which could potentially interfere with the effectiveness of terbinafine treatment.
Some key points to consider when taking terbinafine and corticosteroids together include:
- Monitoring liver function, as both medications can affect the liver, especially in patients with pre-existing liver disease, as mentioned in the study by 1
- Being aware of potential side effects, such as increased skin irritation, digestive issues, or signs of liver problems, and contacting your healthcare provider immediately if you experience any unusual symptoms
- Understanding that the specific dosages and duration of treatment will depend on your individual condition, the type of fungal infection being treated, and other health factors
- Noting that terbinafine has minimal drug-drug interactions, but it's still important to consult with your healthcare provider before combining medications, as stated in the study by 1
It's also worth considering the potential benefits of taking terbinafine, as noted in the study by 1, which found that oral terbinafine offers the advantage of once-daily dosing and can be given for briefer periods than skin-based treatments. However, the decision to take terbinafine and corticosteroids together should always be made in consultation with a healthcare provider, taking into account your individual health needs and medical history.
From the Research
Terbinafine and Steroid Combination
- There is evidence to suggest that terbinafine can be used in combination with corticosteroids, specifically topical antifungal-corticosteroid combinations, to treat fungal skin infections and reduce inflammation 2.
- These combinations can concomitantly attenuate inflammation, relieve pruritus, and treat fungal infection.
- However, there is limited information on the use of systemic terbinafine with oral or injectable corticosteroids.
Potential Interactions and Side Effects
- Terbinafine is associated with few interactions with other drugs, but some potential interactions are known, including substances of the group of antidepressants/antipsychotics and some cardiovascular drugs 3.
- The use of terbinafine with tricyclic antidepressants or selective serotonin reuptake inhibitors requires monitoring of clinical response and potential side effects 3.
- There is a case report of a patient who developed acute generalized exanthematous pustulosis and hepatitis while taking terbinafine, and was treated with steroids 4.
- Another case report suggests that terbinafine may be associated with exercise-induced rhabdomyolysis, and patients may need to be cautioned regarding the intensity of exercise while taking this medication 5.
Precautions and Monitoring
- When combining terbinafine with other medications, including corticosteroids, it is essential to monitor for potential interactions and side effects.
- Patients should be cautioned about the potential risks of terbinafine, including liver enzyme elevations and rare but serious side effects such as acute generalized exanthematous pustulosis and hepatitis.
- The use of terbinafine with other medications, including corticosteroids, should be carefully evaluated, and patients should be monitored closely for any adverse effects 3, 2, 4, 5, 6.
