To @Stef:

If you experience dizziness, headaches and palpitations while taking Karnidin, contact your doctor immediately. If it is not possible to visit the site, I encourage you to take advantage of the teleconsultation:

Palpitations can be a symptom of a more serious illness, so it should not be underestimated. Palpitations combined with dizziness, shortness of breath or chest pain are particularly worrying - in such cases, immediate medical consultation is required. Delay can lead to deterioration of health.

I'll take Carnidin, I'll feel dizziness, headaches, palpitations.

Taking Feroplex (an iron preparation) in the morning and a tablet of Metformax 500 (a diabetes medicine) should not affect the effectiveness of the Liberelle contraceptive pill taken in the evening. These medicines do not interact pharmacodynamically or pharmacokinetic with the hormones in the contraceptive pill.

Feroplex is a medicine, used to treat iron deficiency and anaemia, and is only available with a prescription. Metformax 500 is a diabetes medicine used to treat type 2 diabetes, especially in people who are overweight.

I would also like to know if taking Feroplex and one tablet of Metformax 500 in the morning can affect the effectiveness of Liberella tablets if taken in the evening?

Yes, you can. There are no contraindications to the simultaneous use of the preparations mentioned in the question.

Myconafine (terbinafine) is an antifungal drug that is metabolized by the liver. There is a theoretical possibility that drugs that affect liver enzymes may affect the metabolism of oral contraceptives. However, there is no concrete evidence that terbinafine significantly affects the effectiveness of birth control pills.

Dietary supplements, including Belind SR containing vitamins, minerals or other natural ingredients, usually do not affect the effectiveness of oral contraceptives. However, it's always a good idea to be aware of the ingredients you're taking and their potential interactions. https://www.gdziepolek.pl/produkty/95143/belid-sr-tabletki/apteki

I also wanted to ask if I can use Amorolak nail polish twice a week without worrying about reducing the effectiveness of Liberella tablets?
